How do I pass touch events through to parentViewController? - iphone

I have a UIViewContoller with a few container(child) UIiewsController. The main UIViewController (mvc) contains:
1.) A UICollectionView that occupies the entire view of mvc (it is above mvc.view but below all other controls).
2.) A UIViewController that displays search options (s1vc)
3.) another similar to #2 (s2vc)
4.) another similar to #2 (s3vc)
I have added gesture recognizers to mvc so that a user can hide/show each of the child view controllers by swiping them off of the screen.
The problem is that when a user swipes any of the svcs off of the screen, they cannot scroll the mvc's collectionView.
Here is how I am hiding/showing the svcs:
-(void)swipeLeftGestureHandler:(UIGestureRecognizer*)gestureRecognizer{
SMLOG(#"Swiped Left");
if([SMUser activeUser] == nil) return;
if([self gestureHorizontalScreenSide:gestureRecognizer] == kHorizontalScreenSideLeft){
[self hideFacets];
}
else{
[self showAccordion];
}
}
-(void)swipeRightGestureHandler:(UIGestureRecognizer*)gestureRecognizer{
SMLOG(#"Swiped Right");
if([SMUser activeUser] == nil) return;
if([self gestureHorizontalScreenSide:gestureRecognizer] == kHorizontalScreenSideLeft){
[self showFacets];
}
else{
[self hideAccordion];
}
}
-(void)hideFacets{
if(self.facetVisible == NO) return;
[UIView animateWithDuration:0.25
animations:^{
CGRect newFrame = self.facetViewController.view.frame;
newFrame.origin = CGPointMake(newFrame.origin.x - newFrame.size.width, newFrame.origin.y);
self.facetViewController.view.frame = newFrame;
self.facetVisible = NO;
}
completion:^(BOOL finished){
self.facetViewController.view.hidden = YES;
self.facetViewController.view.userInteractionEnabled = NO;
}];
}
-(void)showFacets{
if([SMUser activeUser] == nil) return;
if(self.facetVisible == YES) return;
self.facetViewController.view.userInteractionEnabled = YES;
[UIView animateWithDuration:0.25
animations:^{
self.facetViewController.view.hidden = NO;
CGRect newFrame = self.facetViewController.view.frame;
newFrame.origin = CGPointMake(newFrame.origin.x + newFrame.size.width, newFrame.origin.y);
self.facetViewController.view.frame = newFrame;
self.facetVisible = YES;
}
completion:^(BOOL finished){
}];
}
As you can see I'm toggling the svc.view.hidden property and then I also tried toggling th svc.userInteractionEnabled.property but no luck. Still cannot swipe the collection view by swiping where the facets view controller was/is.
Any ideas?

The solution here is to add another outlet (using IB) for the container view in the parentViewController (I called it facetContainerView in this code) and then set it's userInteractionEnabled property.
-(void)hideFacets{
if(self.facetVisible == NO) return;
self.facetVisible = NO;
[UIView animateWithDuration:0.25
animations:^{
CGRect newFrame = self.facetViewController.view.frame;
newFrame.origin = CGPointMake(newFrame.origin.x - newFrame.size.width, newFrame.origin.y);
self.facetViewController.view.frame = newFrame;
}
completion:^(BOOL finished){
self.facetViewController.view.hidden = YES;
self.facetContainerView.userInteractionEnabled = NO;
}];
}
-(void)showFacets{
if(self.facetVisible == YES) return;
self.facetVisible = YES;
self.facetContainerView.userInteractionEnabled = YES;
[UIView animateWithDuration:0.25
animations:^{
self.facetViewController.view.hidden = NO;
CGRect newFrame = self.facetViewController.view.frame;
newFrame.origin = CGPointMake(newFrame.origin.x + newFrame.size.width, newFrame.origin.y);
self.facetViewController.view.frame = newFrame;
}
completion:^(BOOL finished){
}];
}
I was curious as to how this new view outlet was different from self.facetViewController.view, so I inserted this code to compare addresses (they are different indeed). I'm not sure about the heirarchy, but it seems that there is an extra view layer that I was not aware of.
NSLog(#"self.facetViewController.view: %p", self.facetViewController.view);
NSLog(#"self.facetContainerView: %p", self.facetContainerView);
Hopefully this will help someone at some point.

SubViews not getting removed

Can someone tell me why this code isn't removing the subview that's being animated? The views are stacking up and the second time I dismiss the view, it won't animate and there are now two instances of subView with tag 99. It wasn't released the first time.
for (UIView *subview in [self.smallView subviews]) {
NSLog(#"view:%#",subview);
if (subview.tag == 99) {
[UIView animateWithDuration:.5
animations:^{
subview.alpha = 0;
}
completion:^(BOOL finished){
subview.alpha = 0;
[subview removeFromSuperview];
}];
}
}
Here's how I add the subview, viewVC is a ViewController Subclass and smallView is where I add my map and is the container for all the views.
#property (nonatomic, retain) CustomViewController *viewVC;
viewVC = [self.storyboard instantiateViewControllerWithIdentifier:#"VIEWVC"];
viewVC.view.frame = CGRectMake(20, 20, 280, 371);
viewVC.view.layer.cornerRadius = 15;
viewVC.view.tag = 99;
viewVC.view.alpha = 0;
[self.smallView addSubview:viewVC.view];
[UIView animateWithDuration:.5
animations:^{
viewVC.view.alpha = 1;
}
completion:^(BOOL finished){
viewVC.view.alpha = 1;
}];
I think the problem might be that you're removing an object from the array you're iterating through, which will cause problems. Try this:
NSArray *subviews = [NSArray arrayWithArray:[self.smallView subviews]];
for (UIView *subview in subviews) {
NSLog(#"view:%#",subview);
if (subview.tag == 99) {
[UIView animateWithDuration:.5
animations:^{
subview.alpha = 0;
}
completion:^(BOOL finished){
subview.alpha = 0;
[subview removeFromSuperview];
}];
}
}
This way, you are no longer removing an object from the array you are iterating through.
Could you please clarify why you are checking for the value of subview.tag to be 99? Is it at all possible that the code in the if statement isn't getting called at all? Throw in some NSLog calls, and see if your code within that if statement is even executing. If it is, then you should check out the methods that you are invoking within the if statement and make sure that they are all okay.

Create UILabel on any view controller from a method

I have a method that gets called if a video upload to Facebook has failed. If that method is called then I would like for a UILabel to briefly appear in any view controller that a user happens to be on at the time the upload fails.
Is this possible?
I asked a similar question earlier about a UIAlertView, but I realized that there are certain circumstances under which an alert could negatively impact user experience.
You can do this is many ways -
1) you can add UILabel to your applications main Window.
2) if you are using a UINavigationController then you get the instance of current viewcontroller and then can add UILabel to its view.
3) if you are using a UITabBarController in this case you can also get the instance of current viewcontroller by accessing tabBarController's selected viewcontroller.
this code Im posting below is from HackBook sample app from facebook. they done similar to what you want.
- (void)showMessage:(NSString *)message {
CGRect labelFrame = messageView.frame;
labelFrame.origin.y = [UIScreen mainScreen].bounds.size.height - self.navigationController.navigationBar.frame.size.height - 20;
messageView.frame = labelFrame;
messageLabel.text = message;
messageView.hidden = NO;
// Use animation to show the message from the bottom then
// hide it.
[UIView animateWithDuration:0.5
delay:1.0
options: UIViewAnimationCurveEaseOut
animations:^{
CGRect labelFrame = messageView.frame;
labelFrame.origin.y -= labelFrame.size.height;
messageView.frame = labelFrame;
}
completion:^(BOOL finished){
if (finished) {
[UIView animateWithDuration:0.5
delay:3.0
options: UIViewAnimationCurveEaseOut
animations:^{
CGRect labelFrame = messageView.frame;
labelFrame.origin.y += messageView.frame.size.height;
// UIView *messageView; declared in header
messageView.frame = labelFrame;
}
completion:^(BOOL finished){
if (finished) {
messageView.hidden = YES;
messageLabel.text = #"";
}
}];
}
}];
}

Showing UI Element with Animation on iPhone

Is there a way to do the following without an instant hide/unhide? Or do I have to make everything a separate view or something complicated? A simple fade in fade out like the modal transition style is all I'm looking for.
-(IBAction)someMethod
{
UIButton.hidden = NO;
tableView.hidden = NO;
}
-(void)viewDidLoad
{
UIbutton.hidden = YES;
tableView.hidden = YES;
}
[UIView animateWithDuration:2.0f
animations:^ {
UIButton.alpha = 1;
UIButton.hidden = NO;
tableView.alpha = 1
tableView.hidden = NO;
}];
Do the opposite for hide and change the duration to your need.
You could animate the alpha value:
[UIView animateWithDuration:0.5f animations:^{
button.alpha = 0.0f;
tableView.alpha = 0.0f;
}];
and it's counterpart
[UIView animateWithDuration:0.5f animations:^{
button.alpha = 1.0f;
tableView.alpha = 1.0f;
}];

How can we implement pagecurl animation in tableview?

Ha ii every body ,how can we implement a page-curl in tableview,i have a tableview which contains pages of the book and i have implement the touch events in the tableview cell for next chapter and previous chapter,left-swipe for next and right-swipe for previous chapter,when we swipe the tableview it reloads the next chapter and previous chapter content,it really works well but i want it in a page-curl animation,when the user swipe left or right tableview loads content with a page-curl animation.Is that possible to do in a tableview cell?my code for left and right swipe for chapter navigation as follows.
-(void) handleSwipeGesture:(UISwipeGestureRecognizer*)recognizer {
if(![delegate.selectedChapter isEqualToString:[NSString stringWithFormat:#"%d",[DbHandler mNumberOfChaptersInBook:delegate.selectedBook]]]) {
// if the currentChapter is the last then do nothing
delegate.selectedChapter = [NSString stringWithFormat:#"%d",[delegate.selectedChapter intValue] + 1];
[delegate reloadVerses];
[self resetReadViewToVerse:1];
[table removeGestureRecognizer:recognizer];
}
if (recognizer.state==UIGestureRecognizerStateBegan ) {
self.table.scrollEnabled = NO;
}
else if(recognizer.state==UIGestureRecognizerStateEnded) {
self.table.scrollEnabled = YES;
}
return;
}
-(void) handleSwipeGestureleft:(UISwipeGestureRecognizer*)recognizer {
if(![delegate.selectedChapter isEqualToString:#"1"])
{
delegate.selectedChapter = [NSString stringWithFormat:#"%d",[delegate.selectedChapter intValue] - 1];
[delegate reloadVerses];
[self resetReadViewToVerse:1];
[table removeGestureRecognizer:recognizer];
}
if (recognizer.state==UIGestureRecognizerStateBegan ) {
self.table.scrollEnabled = NO;
}
else if(recognizer.state==UIGestureRecognizerStateEnded) {
self.table.scrollEnabled = YES;
}
return;
}
Thanks in advance.
I got the answer.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[UIView setAnimationDelay:0.0];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDidStopSelector:#selector(animCompleteHandler:finished:context:)];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[UIView commitAnimations];
just put this code inside the methods.Thanks

Iphone: Is it possible to hide the TabBar? (Pre-iOS 8)

I have an application that uses a UITabBarController to switch between modes. When in a certain mode, I'd like to hide the tab bar until the steps of that mode have been completed. Note that I'm not using a navigation controller so I can't use the setHidesBottomBarWhenPushed method on the navigation controller to hide the tab bar.
Prior to iOS 8, When I attempt to hide the tarbar using:
self.tabBarController.tabBar.hidden = YES
the tab bar goes away, but it leaves a 50 pixel blank area at the bottom of the screen where the tab bar used to be. I can't seem to figure out how to fill that area. Anything in the UI that is in that area is clipped and cannot be seen.
Any ideas if this is even possible? I'd really like to stay away from the navigation controller.
Here's my code for that:
This is, of course, mucking with the goings on in the controller's view hierarchy. It could change/break. This uses defined APIs, so Apple won't care, but they won't care about breaking your code, either.
- (void)hideTabBar {
UITabBar *tabBar = self.tabBarController.tabBar;
UIView *parent = tabBar.superview; // UILayoutContainerView
UIView *content = [parent.subviews objectAtIndex:0]; // UITransitionView
UIView *window = parent.superview;
[UIView animateWithDuration:0.5
animations:^{
CGRect tabFrame = tabBar.frame;
tabFrame.origin.y = CGRectGetMaxY(window.bounds);
tabBar.frame = tabFrame;
content.frame = window.bounds;
}];
// 1
}
- (void)showTabBar {
UITabBar *tabBar = self.tabBarController.tabBar;
UIView *parent = tabBar.superview; // UILayoutContainerView
UIView *content = [parent.subviews objectAtIndex:0]; // UITransitionView
UIView *window = parent.superview;
[UIView animateWithDuration:0.5
animations:^{
CGRect tabFrame = tabBar.frame;
tabFrame.origin.y = CGRectGetMaxY(window.bounds) - CGRectGetHeight(tabBar.frame);
tabBar.frame = tabFrame;
CGRect contentFrame = content.frame;
contentFrame.size.height -= tabFrame.size.height;
}];
// 2
}
Edit:
An anonymous user has suggested the following addition for 7.0 (i have not tested this, and could not say whether it is a workaround or an ideal implementation):
// 1. To Hide the black line in IOS7 only, this extra bit is required
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
[self.tabBarController.tabBar setTranslucent:YES];
}
// 2. For IOS 7 only
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
[self.tabBarController.tabBar setTranslucent:NO];
}
Edit: Entirely untested in 8.x and likely lacking in some layouts.
Like Steve, I haven't found a clean way to do this (even though Apple Photopicker does something similar). Here is what I have done:
if (systemAction)
{
// Reveal tab bar back
CGRect bounds = [[UIScreen mainScreen] bounds];
CGRect tabBarFrame = self.tabBarController.tabBar.frame;
self.tabBarController.view.frame = CGRectMake(0,0,bounds.size.width,bounds.size.height);
self.toolBar.hidden = YES;
systemAction = NO;
}
else
{
//hide tab bar
CGRect bounds = [[UIScreen mainScreen] bounds];
CGRect tabBarFrame = self.tabBarController.tabBar.frame;
CGRect navigationBarFrame = self.navigationController.navigationBar.frame;
self.tabBarController.view.frame = CGRectMake(0,0,bounds.size.width,bounds.size.height+tabBarFrame.size.height);
self.toolBar.hidden = NO;
CGRect frame = self.toolBar.frame;
frame.origin.y = bounds.size.height - frame.size.height - navigationBarFrame.size.height;
self.toolBar.frame = frame;
systemAction = YES;
}
What it is doing is pushing the view down so I can display a toolbar (and not hiding it). Obviously this is for only the 'root view' of a tabbar + navigation controller. For any subsequent views you can set the 'hidesBottomBarWhenPushed' on the viewcontroller you are pushing.
I tried a number of the solutions above, but no joy in iOS 8. I find that setting in viewWillAppear the following works for me. Should work in iOS 7 as the extendedLayoutIncludesOpaqueBars was introduced then.
self.extendedLayoutIncludesOpaqueBars = true
self.tabBarController?.tabBar.isHidden = true
self.tabBarController?.tabBar.isOpaque = true
and if you need to turn tabBars on again when you leave to use the following in viewWillDisappear.
self.tabBarController?.tabBar.isHidden = false
self.tabBarController?.tabBar.isOpaque = false
I use this to allow a return from a transition to keep the TabBar hidden. Not used it in a button action but if like me you find nothing above now works, this could be the basis of a programmable solution.
It's a bit late in the day, but of all the answers to the question that I've trawled through this afternoon, this is the one that worked best for me.
How to hide uitabbarcontroller

[UIView setAnimationDuration:0.5];
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
}
}
[UIView commitAnimations];
}
- (void)showTabBar:(UITabBarController *) tabbarcontroller
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
for(UIView *view in tabbarcontroller.view.subviews)
{
NSLog(#"%#", view);
if([view isKindOfClass:[UITabBar class]])
{

}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
}
}
[UIView commitAnimations];
}
I use only this single line to achieve this. I use prepareForSegue method before showing the view controller having the tab bar.
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:#"showLogin"]){
[segue.destinationViewController setHidesBottomBarWhenPushed:YES];
}
}
I had worked on almost the same case, actually used the code from http://www.developers-life.com/hide-uitabbarcontrolleruitabbar-with-animation.html and made it better according to my needs, this might help others too.
I am using a UISplitViewController as the root view controller and its detail portion is a UITabBarController, I had to hide the tabbar in portrait mode:
// In UITabBarController's custom implementation add following method,
// this method is all that will do the trick, just call this method
// whenever tabbar needs to be hidden/shown
- (void) hidetabbar:(NSNumber*)isHidden {
UITabBarController *tabBarController=self;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
CGRect tabbarFrame=CGRectZero;
for(UIView *theView in tabBarController.view.subviews) {
//NSLog(#"%#", view);
if([theView isKindOfClass:[UITabBar class]]) {
tabbarFrame=theView.frame;
if ([isHidden boolValue]) {
tabbarFrame=CGRectMake(tabbarFrame.origin.x,
tabBarController.view.frame.size.height,
tabbarFrame.size.width,
tabbarFrame.size.height);
} else {
tabbarFrame=CGRectMake(tabbarFrame.origin.x,
tabBarController.view.frame.size.height - tabbarFrame.size.height,
tabbarFrame.size.width,
tabbarFrame.size.height);
}
theView.frame=tabbarFrame;
break;
}
}
for(UIView *theView in tabBarController.view.subviews) {
if(![theView isKindOfClass:[UITabBar class]]) {
CGRect theViewFrame=theView.frame;
if ([isHidden boolValue]) {
theViewFrame=CGRectMake(theViewFrame.origin.x,
theViewFrame.origin.y,
theViewFrame.size.width,
theViewFrame.size.height + tabbarFrame.size.height);
} else {
theViewFrame=CGRectMake(theViewFrame.origin.x,
theViewFrame.origin.y,
theViewFrame.size.width,
theViewFrame.size.height - tabbarFrame.size.height);
}
theView.frame=theViewFrame;
}
}
[UIView commitAnimations];
}
I used following code to call the hidetabbar: method
//In my UISplitViewController's custom implementation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
#synchronized(self){
//change the self.splitDetailController to your UITabBarController's object
[self.splitDetailController
performSelector:#selector(hidetabbar:)
withObject:[NSNumber numberWithBool:UIInterfaceOrientationIsLandscape(interfaceOrientation)]
afterDelay:0.5];
}
return YES;
}
I tested this code to work in simulator only, let me know if it works on device too ;-)
Do you have the autoResizingMask set on the sub view?
view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
Something like that should do the trick and allow the view sitting atop the stack to re-size.
The obvious solution, keeping your original architecture, would have been to present that view modally:
- (void)tabBarController:(UITabBarController *)tb
didSelectViewController:(UIViewController *)vc {
if (tb.selectedIndex == MODALONE) {
UIViewController* mod =
[[UIViewController alloc] initWithNibName: #"ModalView"
bundle: nil];
[tb presentModalViewController:mod animated:NO];
[mod release];
}
}
The view now covers the entire screen (except for the status bar is there is one) including the tab bar, so it looks as if the tab bar has gone away in response to the user pressing that tab bar item.
autoresizing mask has an enumeration. Try to set all the options and check if autoresize subviews option is checked in parent view
You can create Tabbar Category and show/Hide easily. and you can access full view.
create category #import "UITabBarController+HideTabBar.h"
#implementation UITabBarController (HideTabBar)
- (void)hideTabBarAnimated:(BOOL)animated
{
CGRect statusbarFrame = [UIApplication sharedApplication].statusBarFrame;
CGRect tabBarControllerFrame = self.view.frame;
if (statusbarFrame.size.height>20)
{
tabBarControllerFrame.size.height = screenSize.size.height + self.tabBar.frame.size.height - 20.0;
}
else
{
tabBarControllerFrame.size.height = screenSize.size.height + self.tabBar.frame.size.height ;
}
if (animated) {
[UIView animateWithDuration:0.2 animations:^{
[self.view setFrame:tabBarControllerFrame];
} completion:^(BOOL finished) {
}];
}
else
[self.view setFrame:tabBarControllerFrame];
}
- (void)showTabBarAnimated:(BOOL)animated {
CGRect statusbarFrame = [UIApplication sharedApplication].statusBarFrame;
CGRect tabBarControllerFrame = self.view.frame;
if (statusbarFrame.size.height>20)
{
tabBarControllerFrame.size.height = screenSize.size.height - 20.0;
}
else
{
tabBarControllerFrame.size.height = screenSize.size.height ;
}
if (animated) {
[UIView animateWithDuration:0.2 animations:^{
[self.view setFrame:tabBarControllerFrame];
} completion:^(BOOL finished) {
}];
}
else
[self.view setFrame:tabBarControllerFrame];
}
#end
Note : use statusbarFrame is used when hotspot or call is ON so tabbar would not cut down.
Now Import category in which you class you want to use methods and just call below methods to hide or show tabbar.
[self.tabBarController hideTabBarAnimated:YES];
[self.tabBarController showTabBarAnimated:YES];
Hope this Helps.
Hope this works.

Here is my solution (my tab view controller is inside navigation controller for good measure)... So I have subclassed UITabBarController and did this... exposing -setTabBarHidden: method
- (void)setTabBarHidden:(BOOL)hidden {
_tabBarHidden = hidden;
[UIView performWithoutAnimation:^{
[self adjustViews];
}];
}
- (void)adjustViews {
if ( _tabBarHidden ) {
CGRect f = self.tabBar.frame;
// move tab bar offscreen
f.origin.y = CGRectGetMaxY(self.view.frame);
self.tabBar.frame = f;
// adjust current view frame
self.selectedViewController.view.frame = self.view.frame;
} else {
CGRect f = self.tabBar.frame;
// move tab bar on screen
f.origin.y = CGRectGetMaxY(self.view.frame) - (CGRectGetMaxY(self.tabBar.bounds) + CGRectGetMaxY(self.navigationController.navigationBar.frame));
self.tabBar.frame = f;
// adjust current view frame
f = self.view.bounds;
f.size.height -= CGRectGetMaxY(self.tabBar.bounds);
self.selectedViewController.view.frame = f;
}
}
- (void)viewWillLayoutSubviews {
[super viewWillLayoutSubviews];
[UIView performWithoutAnimation:^{
[self adjustViews];
}];
}
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
[UIView performWithoutAnimation:^{
[self adjustViews];
}];
}
put the statement in the init method of the UIViewController
override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
self.hidesBottomBarWhenPushed = true
setupDependencyConfigurator()
}
See this thread:
Show/Hide TabBarController in iphone
In summary, you can see an example of this behavior in this sample code:
http://developer.apple.com/iphone/library/samplecode/TheElements/index.html
Why are you not using a navigation controller. It's a lot easier to hide the nav bar than the tab bar...
Just made the following code in Monotouch inside a subclass of UITabBarController:
public void ShowTabBar()
{
UIView.BeginAnimations("Anim");
UIView.SetAnimationDuration(0.25f);
this.View.Subviews[0].Frame = new RectangleF(0f, 0f, 320f, 431f);
this.TabBar.Frame = new RectangleF(0f, 431f, 320f, 49f);
this.TabBar.Hidden = false;
UIView.CommitAnimations();
}
public void HideTabBar()
{
UIView.BeginAnimations("Anim");
UIView.SetAnimationDuration(0.25f);
this.View.Subviews[0].Frame = new RectangleF(0f, 0f, 320f, 480f);
this.TabBar.Frame = new RectangleF(0f, 481f, 320f, 510f);
this.TabBar.Hidden = true;
UIView.CommitAnimations();
}
