In my didSelectRowAtIndexPath method I call [self dismissView]; when the user selects a cell in order to dismiss the view if its already been presented. This clearly isn't very optimal and its overriding the presentView method without it animating the dismissView. Is there a better way to do this? Or at the very least let it wait for the view to finish animating without using NSTimer.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
[self dismissView];
// Do xyz...
[self presentView:twitterLinksView];
Then..
- (void)presentView:(id)sender
{
twitterLinksView.frame = CGRectMake(0, (self.view.frame.size.height + viewHeight), 320, 300);
[UIView animateWithDuration:0.60f animations:^{
CGRect twitterLinkFrame = self.twitterLinksView.frame;
twitterLinkFrame.origin.y = (self.view.frame.size.height - viewHeight);
twitterLinksView.frame = twitterLinkFrame;
}];
}
- (void)dismissView
{
[UIView animateWithDuration:0.75f animations:^{
CGRect twitterLinkFrame = self.twitterLinksView.frame;
twitterLinkFrame.origin.y = (self.view.frame.size.height + viewHeight);
self.twitterLinksView.frame = twitterLinkFrame;
}];
}
[UIView animateWithDuration:1. animations:^{
//firstAnimationBlock
} completion:^(BOOL finished){
[UIView animateWithDuration:1. animations:^{
//animations in this block will be called after firstAnimationBlock has expired
}];
}];
as i understand you wanna fire 2 animation one after the other. this code (block inside block) makes this
this part is after edit:
ok now you can try writing like that
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
[self dismissView];
// Do xyz...
[self performSelector:#selector(presentView:) withObject:twitterLinksView afterDelay:0.75];
//[self presentView:twitterLinksView];
}
I ended up splitting out my creation method and using [[self.view subviews] containsObject:twitterLinksView] to check for the view. Also to be noted is [self performSelector:#selector(createView) withObject:twitterLinksView afterDelay:0.76f] had to be very slightly ahead of the dismissing animation for it to work at all... yeah wtf.
In the didSelectRowAtIndexPath method i used [self performSelector:#selector(presentView:)];
Thanks to meth for solving part of the puzzle.
- (void)presentView:(id)sender
{
if ([[self.view subviews] containsObject:twitterLinksView])
{
[self dismissView];
[self performSelector:#selector(createView) withObject:twitterLinksView afterDelay:0.76f];
NSLog(#"Animating ut old");
}
else
{
NSLog(#"Creating new view");
[self createView];
}
}

In my iPhone App I need to display a modal view with transparent background and it should appear with animation like it is appearing from center of view and its size is increasing.
similar like "drawing something" iPhone App when we click on settings button.
How do I do this?
You can do one of 4 following transition styles:
viewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
viewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
viewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
viewController.modalTransitionStyle = UIModalTransitionStylePartialCurl;
[self presentModalViewController:viewController animated:YES];
If you want something that is not included in these defaults you are going to have to build your own custom animation for presenting the modal view. Like the following but obviously for the style you want.
UIModalTransitionStyle horizontal movement
Let's say you have a viewController thats called aScoreSheet that you want to present. Try to define this method in the view controller that's going to do the presenting.
-(void) presentTransparentModalViewController: (ScoreSheet *) aViewController
{
scoreSheet = aViewController;
UIView *view = aViewController.view;
view.opaque = NO;
[view.subviews enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
UIView *each = obj;
each.opaque = NO;
}];
[self.view addSubview:view];
view.center = CGPointMake(160, 800); //for iPhone
[UIView animateWithDuration:0.9 delay:0 options:UIViewAnimationCurveEaseInOut animations:^{
view.center = CGPointMake(160, 240);
} completion:^(BOOL finished) {
self.view.userInteractionEnabled=YES;
}];
}
and then to dismiss the controller:
-(void) dismissTransparentModalViewControllerAnimated:(BOOL) animated{
if (animated) {
[UIView animateWithDuration:0.4
animations:^{
scoreSheet.view.center = CGPointMake(scoreSheet.view.center.x, scoreSheet.view.center.y + 480);
} completion:^(BOOL finished) {
[scoreSheet.view removeFromSuperview];
scoreSheet = nil;
}];
}
}
Not a full answer, but maybe you can take a look at this open source library:
https://github.com/Split82/HMGLTransitions
It has some custom modal transitions, maybe not exactly the one you are looking for, but you can easily add your transition by subclassing HMGLTransition.
Hope this helps
I want to load another view controller so the current slides up while the new one is coming from bottom, it works but I don't get the subviews (buttons disappear and I only get the blank view), how to fix it?
Current code is:
-(void)perform {
UIViewController *sourceVC = (UIViewController *) self.sourceViewController;
UIViewController *destinationVC = (UIViewController *) self.destinationViewController;
[UIView animateWithDuration:2.0
animations:^{
destinationVC.view.frame=CGRectMake(destinationVC.view.frame.origin.x, 480, destinationVC.view.frame.size.width, destinationVC.view.frame.size.height);
sourceVC.view.transform=CGAffineTransformMakeTranslation(0, -480);
destinationVC.view.transform=CGAffineTransformMakeTranslation(0, -480);
}];
}
You can create 2 views for your viewController, and set second view origin.y = window.height
Then animate like this -
CGRect outFrame = CGRectMake(0, 320, 320, 322);
[UIView animateWithDuration:0.50f
delay:delay
options:UIViewAnimationOptionCurveEaseInOut
animations:^{
fromView.frame = outFrame;
toView.frame = CGRectMake(0, 0, 320, 322);
} completion:nil];
something like this...
I like to replicate the form behavior of Safari on the iPhone in my own app. If you enter data in an web form you get a separate UIToolbar (previous, next, done) just above the UIKeyboardView. Same for choosing an option: you get the same UIToolbar just above an UIPickerView.
I am looking for demos / sourcode / ideas how to implement this. Would I create my own subview with that toolbar and textview / pickerview? Is there a more elegant way? Especially something that leverages becomeFirstResponder of UITextfield?
So i created a UIViewCOntroller subclass to manage this.
on that i wrote this function to add.
-(void) addToViewWithAnimation:(UIView *) theView
{
UIView* myview = self.view;
CGRect frame = myview.frame;
frame.origin.y = 420;
myview.frame = frame;
UIView* bgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 420)];
bgView.backgroundColor = [UIColor blackColor];
bgView.alpha = 0.6;
backgroundView = bgView;
[theView addSubview: bgView]; // this adds in the dark background
[theView addSubview:self.view]; // this adds in the pickerView with toolbar.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
frame = myview.frame;
frame.origin.y = 420 - frame.size.height;
myview.frame = frame;
[UIView commitAnimations];
}
I then created the view in IB, here is what my class Header looked like at the end of that. (there is also a UItoolbar on the view i just do not have a reference to it in my Controller)
#interface PropertyPickerController : UIViewController {
IBOutlet UIPickerView* Picker;
IBOutlet UIButton* DoneButton;
IBOutlet UIButton* CancelButton;
UIView* backgroundView;
NSArray* SimpleObjects;
id PickerObjectDelegate;
SEL PickerObjectSelector;
}
To then hide the view i use.
-(void) removeFromSuperviewWithAnimation
{
UIView* myview = self.view;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(AnimationDidStop:)];
[UIView setAnimationDuration:0.5];
// set fram below window.
CGRect frame = myview.frame;
frame.origin.y = 420;
myview.frame = frame;
backgroundView.alpha = 0; //fades shade to nothing
[UIView commitAnimations];
}
-(void) AnimationDidStop:(id) object
{
[self.view removeFromSuperview]; //removes view after animations.
[backgroundView removeFromSuperview];
}
And last but not least all the delegate functions for the picker.
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
FBSimpleObject* object = (FBSimpleObject*)[SimpleObjects objectAtIndex:row];
return object.Name;
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{ return 1;}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
return [SimpleObjects count];
}
- (IBAction)CancelButtonClick
{
[self removeFromSuperviewWithAnimation];
}
- (IBAction)DoneButtonClick
{
//This performs a selector when the done button is clicked, makes the controller more versatile.
if(PickerObjectDelegate && PickerObjectSelector)
{
NSMethodSignature* signature = [PickerObjectDelegate methodSignatureForSelector:PickerObjectSelector];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
[invocation setTarget:PickerObjectDelegate];
[invocation setSelector:PickerObjectSelector];
[invocation setArgument:&object atIndex:2];
[invocation retainArguments];
[invocation invoke];
}
}
This is how you do the ToolBar. Basically i use the same concept with a ViewController subclass, and i dont use the standard push view or modal display options. (the example here actually places a Textbox and a toolbar on top of the keyboard.
#interface BugEditCommentController : UIViewController {
UITextView* Comment;
UIToolbar* Toolbar;
}
-(void) addToViewWithAnimation:(UIView*) theView;
To activate this view usually you would call [object becomeFirstResponder];
so if you add this to your view Controller constructor, all you need to do is call [object becomeFirstResponder];
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self selector:#selector(keyboardWillShow:) name: UIKeyboardWillShowNotification object:nil];
[nc addObserver:self selector:#selector(keyboardWillHide:) name: UIKeyboardWillHideNotification object:nil];
abd if you implement this method on your controller (defined in the above code)
-(void) keyboardWillShow:(NSNotification *) note
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
CGRect toolbarFrame = Toolbar.frame;
CGRect keyboardFrame;
CGPoint keyboardCenter;
[[note.userInfo valueForKey:UIKeyboardCenterEndUserInfoKey] getValue:&keyboardCenter];
[[note.userInfo valueForKey:UIKeyboardBoundsUserInfoKey] getValue: &keyboardFrame];
//CGRect toolbarRect = Toolbar.center;
toolbarFrame.origin.y= keyboardCenter.y - ((keyboardFrame.size.height/2) + (toolbarFrame.size.height));
Toolbar.frame = toolbarFrame;
[UIView commitAnimations];
}
-(void) keyboardWillHide:(id) object
{
//you could call [self removeFromSuperviewHere];
}
-(void) removeFromsuperViewWithAnimation
{
[Comment resignFirstResponder];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(AnimationDidStop:)];
CGRect frame = Toolbar.frame;
frame.origin.y = 480;
Toolbar.frame = frame;
[self.view viewWithTag:1].alpha = 0; //fade transparent black background to clear.
[UIView commitAnimations];
}
-(void)AnimationDidStop:(id) object
{
[self.view removeFromSuperview];
}
hope the additional info helps.
I'm looking for the solution for this issue too.
I found this was the best solution, you can use this SCKit to add tool bar to dismiss the UIPickerView or the UIDatePicker as you want.
Following is github link: https://github.com/scelis/SCKit/tree/
Have fun!
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.

else
{

}
}

}
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();
}
