I am trying to get a UIView to sit on top of the status bar, but currently have had no success. I have tried the following:
view.window?.windowLevel = UIWindowLevelStatusBar + 1 // view being a UIView() object
I have also tried:
let win: UIWindow = UIWindow( )
win.frame = CGRect( x: 0, y: 0, width: 100, height: Display.height )
win.windowLevel = UIWindowLevelStatusBar + 1
win.hidden = false
win.backgroundColor = UIColor.blueColor()
win.makeKeyAndVisible()
In all cases the status bar is still on top. Has anyone got this to work in Swift yet?
This is my simple solution (you can also use MTStatusBarOverlay - check git hub).
first initialise the window. Do that after you set makeKeyAndVisible on your main window.
self.syncMessageWindow = [[UIWindow alloc] initWithFrame:messageRect];
self.syncMessageWindow.clipsToBounds = YES;
self.syncMessageWindow.frame = messageRect;
self.syncMessageWindow.windowLevel = UIWindowLevelStatusBar+1.f;
self.syncMessageWindow.alpha = 1.f;
self.syncMessageView = [[UIView alloc] initWithFrame:messageRect];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 2, messageRect.size.width-20, 16)];
[label setTag:100];
[label setTextAlignment:NSTextAlignmentCenter];
[label setFont:[UIFont fontWithName:#"HelveticaNeue" size:12.0]];
[label setTextColor:[UIColor whiteColor]];
[self.syncMessageView addSubview:label];
[self.syncMessageWindow addSubview:self.syncMessageView];
[self.syncMessageWindow setRootViewController:[UIApplication sharedApplication].delegate.window.rootViewController];
[self.syncMessageWindow makeKeyAndVisible];
self.syncMessageWindow.hidden = YES;
than show the message
if(self.syncMessageWindow.hidden == YES) {
self.syncMessageWindow.hidden = NO;
[self.syncMessageView setBackgroundColor:color];
[self.syncMessageView setAlpha:1.0];
[self.syncMessageView setFrame:CGRectMake(0, -20, self.syncMessageView.frame.size.width, self.syncMessageView.frame.size.height)];
[self.syncMessageWindow setWindowLevel:UIWindowLevelStatusBar+1];
[((UILabel*)[self.syncMessageView viewWithTag:100]) setText:message];
[UIView animateWithDuration:.3 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
self.syncMessageView.frame = CGRectMake(0, 0, self.syncMessageView.frame.size.width, self.syncMessageView.frame.size.height);
} completion:^(BOOL finished) {
[UIView animateWithDuration:.3 delay:2.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
self.syncMessageView.frame = CGRectMake(0, -20, self.syncMessageView.frame.size.width, self.syncMessageView.frame.size.height);
} completion:^(BOOL finished) {
[self.syncMessageWindow setWindowLevel:UIWindowLevelNormal];
self.syncMessageWindow.hidden = YES;
}];
}];
}
Why don't you hide the status bar? Then you can put the view at the top. See How to hide iOS status bar.
I don't think it is possible to cover the status bar with another view, because all content is behind the status bar by default.

I am doing an app in which i need to draw lines in one view and that automatically should appear in the other view. Any help would be appreciated..
I have tried this..
- (void)viewDidLoad
{
[super viewDidLoad];
slv = [[SmoothLineView alloc] initWithFrame:CGRectMake(DrawingView.bounds.origin.x, DrawingView.bounds.origin.y + 42, DrawingView.bounds.size.width, DrawingView.bounds.size.height - 42)];
slv.delegate = self;
[DrawingView addSubview:slv];
}
-(IBAction)btnAnotherView:(UIButton *)sender
{
[zoomingTypingView setUserInteractionEnabled:YES];
if(sender.tag == 123)
{
[self.view setBackgroundColor:[UIColor colorWithWhite:0.500 alpha:1.000]];
[UIView animateWithDuration:0.5
delay:0.1
options:UIViewAnimationTransitionCurlUp
animations:^{
//animation code
zoomingTypingView.frame = CGRectMake(0, 549, 768, 451);
} completion:^(BOOL finished) {
}];
CGRect imageFrame = CGRectMake(50, 50, 220, 120);
ResizableView = [[SPUserResizableView alloc] initWithFrame:imageFrame];
CGRect gripFrame = CGRectMake(50,50, 220,120);
UIView *zoom = [[UIView alloc]initWithFrame:gripFrame];
UIScrollView *zoomscroll = [[UIScrollView alloc]initWithFrame:gripFrame];
[zoomscroll setZoomScale:32.0];
[zoomscroll setMaximumZoomScale:32.0];
[zoom addSubview:zoomscroll];
[ResizableView setContentView:zoom];
ResizableView.delegate = self;
[DrawingView addSubview:ResizableView];
sender.tag = 246;
}
else
{
[UIView animateWithDuration:0.5
delay:0.1
options:UIViewAnimationTransitionCurlUp
animations:^{
//animation code
zoomingTypingView.frame = CGRectMake(0, 999, 768, 451);
} completion:^(BOOL finished) {
[self.view setBackgroundColor:[UIColor whiteColor]];
}];
[ResizableView removeFromSuperview];
[DrawingView addSubview:slv1];
sender.tag = 123;
}
}
In the above Image WhiteColored View is the new View and if i draw in that whiteColoredView that should reflect in both the views.
You can get more idea by looking at the NOTE TAKER HD APP.
http://www.youtube.com/watch?v=FdGDnUKZcMM
If you have two views defined:
#property(nonatomic) UIView *view1;
#property(nonatomic) UIView *view2;
instead of do self.view, you can have function does the drawing for one view:
-(void)drawView:(UIView*)view{
//your drawing code here
}
And just call the same function twice with passing different views.
In my iOS app when a button is pressed an event is initiated and at the bottom of the screen appears a status message informing the user about a successful or failed operation.
The status message appear and disappear with the following code.
this one show the message
- (void) showMessage:(NSString*)text
{
CGRect frame = [[self view] frame];
if(statusView == nil)
{
messageViewWindow = [[UIWindow alloc] initWithFrame:CGRectMake(0, frame.size.height-29,
frame.size.width, 0)];
statusView = [[StatusMessageView alloc] initWithFrame:CGRectMake(0, 0, frame.size.width, 0)
Text:text
andShowIndicator:NO];
[messageViewWindow addSubview:statusView];
[messageViewWindow makeKeyAndVisible];
}
UILabel *label = [statusView getTextLabel];
UIImageView *imageView = [statusView getBackImageView];
CGSize stringSize = [text sizeWithFont:[Constants getLabelFont]];
int xCoordinate = (messageViewWindow.frame.size.width - stringSize.width)/2;
[UIView beginAnimations:nil context:nil];
messageViewWindow.frame = CGRectMake(0, frame.size.height-59, frame.size.width, 30);
statusView.frame = CGRectMake(0, 0, frame.size.width, 30);
label.frame = CGRectMake(xCoordinate,5,stringSize.width,20);
imageView.frame = CGRectMake(0, 0, frame.size.width, 30);
[UIView commitAnimations];
[NSTimer scheduledTimerWithTimeInterval:2.0f target:self selector:#selector(hideMessage) userInfo:nil repeats:NO];
}
and this one hides the message
- (void) hideMessage
{
UILabel *label = [statusView getTextLabel];
UIImageView *imageView = [statusView getBackImageView];
CGRect labelFrame = label.frame;
[UIView beginAnimations:nil context:nil];
messageViewWindow.frame = CGRectMake(0, [UIScreen mainScreen].applicationFrame.size.height-29, [UIScreen mainScreen].applicationFrame.size.width, 0);
statusView.frame = CGRectMake(0, 0, [UIScreen mainScreen].applicationFrame.size.width, 0);
label.frame = CGRectMake(labelFrame.origin.x, 0, labelFrame.origin.y, 0);
imageView.frame = CGRectMake(0, 0, [UIScreen mainScreen].applicationFrame.size.width, 0);
[UIView commitAnimations];
}
strange thing is that the message is shown and after two seconds dissapears, however the main window lost functionality, like the copy and paste ability.
Do you see something wrong in my methods? Is there any certain way, calling the "animations" code?
Since you are writing [messageViewWindow makeKeyAndVisible];, you have to write [self.view.window makeKeyAndVisible] in hideMessage to let the self.view.window handle all the userinteraction again.
This is because you use a UIWindow to display your view, which is not a good idea (it is not recommended to create UIWindows by yourself, as explained in the "Overview" paragraph of the documentation.
Moreover, you make your window the keywindow but don't restore the standard window at the end when you hide it, thus your problems with the events later.
And last, you use obsolete APIs for the animations, which is deprecated since iOS4 is out (and I guess you don't code for iOS3 or earlier), you should really use the new APIs that have been introducted 3 iOS versions ago now. Besides, it will avoid the overhead to create an NSTimer for that.
So you code can become:
- (void) showMessage:(NSString*)text
{
CGSize sz = self.view.window.frame.size;
CGRect hiddenFrame = CGRectMake(0, sz.height-29, sz.width, 0);
if(statusView == nil)
{
statusView = [[StatusMessageView alloc] initWithFrame:hiddenFrame
text:text
andShowIndicator:NO];
[self.window addSubview:statusView];
}
UILabel *label = [statusView getTextLabel];
UIImageView *imageView = [statusView getBackImageView];
CGSize stringSize = [text sizeWithFont:[Constants getLabelFont]];
int xCoordinate = (sz.width - stringSize.width)/2;
label.frame = CGRectMake(xCoordinate,5,stringSize.width,20);
imageView.frame = CGRectMake(0, 0, frame.size.width, 30);
[UIView animateWithDuration:1.f animations:^{
statusView.frame = CGRectMake(0, sz.height-59, frame.size.width, 30);
} completion:^{
// When show animation is done, schedule the start of the hide animation with a delay of 2 seconds
[UIView animateWithDuration:1.f delay:2.f options:0 animation:^{
statusView.frame = hiddenFrame;
} completion:nil];
}];
}
I'm coding an iPhone TabBar Project with UiNavigation, the first view contain UIScrollView and the scrollview contain views every subview contain imageview,anUiImage and a UiButton follows
is the function that build the first screen
//*******************************************************
//* Build the main screen *
//*******************************************************
-(void) buildScreen{
sing.viewsArray = [[NSMutableArray alloc]init];
int Vve = 10;
int Vho = 10;
int wi = 95;
int hi = 95;
int ArrayIndex = 0;
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 3; j++) {
staticView = [[UIView alloc] initWithFrame:CGRectMake(Vve, Vho, 100, 100)];
[staticView setTag:ArrayIndex];
staticImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[sing.stdPicArray objectAtIndex:ArrayIndex]]];
[staticImage setFrame:CGRectMake(0, 0, wi, hi)];
[staticView addSubview:staticImage];
viewButton = [UIButton buttonWithType:UIButtonTypeCustom];
viewButton.frame = CGRectMake(0, 0, wi, hi);
[viewButton addTarget:self action:#selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
[viewButton setTag:ArrayIndex];
[sing.buttonsArray addObject:viewButton];
[staticView addSubview:viewButton];
[sing.viewsArray addObject:staticView];
[MainScroll addSubview:[sing.viewsArray objectAtIndex:ArrayIndex]];
Vve += 100;
ArrayIndex++;
}
Vve = 10;
Vho += 100;
}
}
When I click on the UiButton I want to add another UIView to the UIScrollView and make a "UIViewAnimationTransitionFlipFromLeft" when the view is added to the scroll view
tried the following code
-(void)animateFlip{
[UIView transitionWithView:flipViewBack
duration:1.0
options:UIViewAnimationTransitionFlipFromLeft
animations:^{ [self.view addSubview:flipViewBack]; }
completion:^(BOOL f){ }];
}
didn't work just added the flipViewBack
-(void)animateFlip{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self.flipViewFront
cache:YES];
[MainScroll addSubview:flipViewFront];
[UIView setAnimationDidStopSelector:#selector(flipAnimationDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
}
didn't work just like the other one, the next code did flip the main view with the view I wanted, but it didn't flip only the the view I want
-(void)animateFlip{
[UIView beginAnimations:nil
context:nil];
[UIView setAnimationDuration:1.0];
[UIView transitionFromView:self.view
toView:flipViewBack
duration:2
options:UIViewAnimationOptionTransitionFlipFromBottom
completion:NULL];
[UIView setAnimationDidStopSelector:#selector(flipAnimationDidStop:finished:context:)];
[UIView setAnimationDelegate:self];
//set transformation
[UIView commitAnimations];
}
Does any body know how to do it' I looked everywhere and all the code I found didn't work for me
Thanks
I tried another option suggested in this link
iPhone subview flip between 2 views and it didn't work for me
this is the function that I use on click in the last 3 lines im adding to the flipView (container) the flipViewFront view then I add the flipView to the mainScroll view and then I go to execute the animation in the animateFlip that I copied from your sample
//*******************************************************
//* Click on the picture as button *
//*******************************************************
-(void) buttonClick:(id) sender{
UIButton *button = (UIButton *)sender;
int row = [button superview].tag;
NSLog(#"Button pressed tag: %i",row);
self.flipView = [[UIView alloc]initWithFrame:CGRectMake(65, 130, 190, 190)];
self.flipView.backgroundColor = [UIColor clearColor];
self.flipViewBack = [[UIView alloc]initWithFrame:CGRectMake(65, 130, 190, 190)];
self.flipViewFront = [[UIView alloc]initWithFrame:CGRectMake(65, 130, 190, 190)];
self.flipViewFront.backgroundColor = [UIColor whiteColor];
self.flipViewImage = [UIImage imageNamed:[sing.stdPicArray objectAtIndex:row]];
self.filpImage = [[UIImageView alloc]initWithImage:self.flipViewImage];
[self.flipViewBack addSubview:self.filpImage];
self.flipCloseButton = [UIButton buttonWithType:UIButtonTypeCustom];
[self.flipCloseButton setFrame:CGRectMake(0, 0, 24, 24)];
[self.flipCloseButton setImage:[UIImage imageNamed:#"close_button.png"] forState:UIControlStateNormal];
[self.flipCloseButton addTarget:self action:#selector(closwFlip:) forControlEvents:UIControlEventTouchUpInside];
[self.flipViewBack addSubview:flipCloseButton];
self.flipOkButton = [[UIButton alloc]initWithFrame:CGRectMake(30, 0, 190, 190)];
[self.flipCloseButton addTarget:self action:#selector(continueTo:) forControlEvents:UIControlEventTouchUpInside];
[self.flipViewBack addSubview:flipOkButton];
[flipView addSubview:flipViewFront];
[MainScroll addSubview:flipView];
[self animateFlip];
}
found the problem, but not the answer, if it works directly from the ViewDidLoad it and the first view is on screen all is well and the flip works' if I change it so that the want to add a view and flip it in one event it shows me the second(flipped) view without the flip
Your problems seems to be that you are trying to animate the flip on the view before it is added to the view hierarchy.
Instead you should add the back view to a common container view (that later will contain the front view) and then flip the container view while adding the front and removing the back, like this:
// Container view is a view that is already added to your view hierarchy.
// It contains the back view. The front view will be added to it.
[UIView transitionWithView:containerView
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[backView removeFromSuperview]; // This is already added to the container
[containerView addSubview:frontView]; // Not yet added ...
}
completion:NULL];
Update
This is all the code I wrote when answering this question. It works for me. If it still doesn't animate for you then you probably haven\t set up your view hierarchy the same way.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
containerView = [[UIView alloc] initWithFrame:CGRectMake(30, 30, 100, 100)];
[self.view addSubview:containerView];
frontView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
[frontView setBackgroundColor:[UIColor orangeColor]];
backView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
[backView setBackgroundColor:[UIColor redColor]];
[containerView addSubview:backView];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self
action:#selector(flip)];
[self.view addGestureRecognizer:tap];
}
- (void)flip {
[UIView transitionWithView:containerView
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[backView removeFromSuperview];
[containerView addSubview:frontView];
}
completion:NULL];
}
Just wondering why and need to solve it. i have this searchbar looks like this.
which clicked will move up to the top and expend to 0,0,320,searchbar's height.
which clicked Cancel, it should resize back to 33,55,270, searchbar's height. but it doesn't
the searchDisplayControllerDidEndSearch will work to resize back, however there is a 1 sec lag that user could see the changes. any body why in searchDisplayControllerWillEndSearch the animation resize wound't work ?.
thanks for the comments and feedback.
- (void) searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller
{
[UIView animateWithDuration:.1
animations:^{
controller.searchResultsTableView.frame = frogTableView.frame;
searchDisplayController.searchResultsTableView.frame = frogTableView.frame;
searchDisplayController.searchBar.frame = CGRectMake(32,
55,
270,
searchDisplayController.searchBar.frame.size.height);
searchBar.frame = CGRectMake(32,
55,
270,
searchBar.frame.size.height);
frogTableView.frame = CGRectMake(frogTableView.frame.origin.x,
121,
frogTableView.frame.size.width,
frogTableView.frame.size.height);
notePad.frame = CGRectMake(notePad.frame.origin.x,

}
completion:^(BOOL finished){
//whatever else you may need to do
}];
}
I had the same trouble after I started to use UISearchBar with UISearchDisplayController. The solution I came up with is to place a search bar on a view:
UIView * searchBarSubview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, MENU_WORK_AREA_WIDTH, SEARCH_BAR_HEIGHT)] ;
searchBarSubview.autoresizesSubviews = YES;
searchBarSubview.backgroundColor = [UIColor clearColor];
UISearchBar * globalSearchBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, MENU_WORK_AREA_WIDTH, SEARCH_BAR_HEIGHT)] autorelease];
globalSearchBar.tintColor = [UIColor blackColor];
globalSearchBar.delegate = self;
[globalSearchBar setBackgroundImage:[UIImage alloc]];
and resize the view instead of search bar in searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.3];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
// Slide in to the final destination
searchBarSubview.frame = CGRectMake(0, 0, MENU_WORK_AREA_WIDTH, SEARCH_BAR_HEIGHT);
[UIView commitAnimations];
I want to create a custom alert view within my iOS application. For example, I want to put some images in this alert, and change its color.
I know how to create a normal UIAlertView, but is there a way to customize an alert view?
I set up my own UIViewController which I can skin with my own images. I generally only use one or two buttons, so I hide the second button if it's not being used. The view is actually the size of the entire screen, so it blocks touches behind it, but it is mostly transparent, so the background shows through.
When bringing it in, I use a few animations to make it bounce like Apple's alert view. Something like this works:
-(void)initialDelayEnded {
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
self.view.alpha = 1.0;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/1.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce1AnimationStopped)];
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.1, 1.1);
[UIView commitAnimations];
}
- (void)bounce1AnimationStopped {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/2];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce2AnimationStopped)];
self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
[UIView commitAnimations];
}
- (void)bounce2AnimationStopped {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/2];
self.view.transform = CGAffineTransformIdentity;
[UIView commitAnimations];
}
I have the possibility of a short delay built into the class, so initialDelayEnded is called when that delay is over.
When initializing, I pass in an object and selector I want called when each button is pressed, and then I call the appropriate selector on the object when a button is pressed.
Here's a custom alert view that I wrote which is a drop-in replacement for UIAlertView. You can set a custom background image; it wouldn't be hard to extend to support custom background colors.
https://github.com/TomSwift/TSAlertView
Create one sub class for UIAlertView.
And create common class for Alert View method.
Add 2 below method for it.

}
}

lbl.frame = frame;
[lbl setCenter:CGPointMake([view bounds].size.width/2, [view bounds].size.height/2)];
}
}
}
}
Now, in whatever class, you are using this custom Alert:
Add below:
#pragma mark UIAlertViewDelegate
-(void)willPresentAlertView:(UIAlertView *)alertView{
if(alertView==objAlertMsg){
/*clsCommonFuncDBAdapter *objclsCommonFuncDBAdapter = [[clsCommonFuncDBAdapter alloc] init];
float newHeight = [objclsCommonFuncDBAdapter getAlertHeightByMessage:alertView.frame.size.width :alertView.message] + [g_AlertExtraHeight intValue];
[objclsCommonFuncDBAdapter release];
//NSLog(#"X = %f, Y = %f, Widht = %f, Height = %f", alertView.frame.origin.x, alertView.frame.origin.y, alertView.frame.size.width, alertView.frame.size.height);
//[alertView setFrame:CGRectMake(alertView.frame.origin.x, alertView.frame.origin.y, alertView.frame.size.width, 110.0)];
[alertView setFrame:CGRectMake(alertView.frame.origin.x, alertView.frame.origin.y, alertView.frame.size.width, newHeight)];*/
}
[clsCommonFuncDBAdapter alertViewBtnText:alertView];
}
For calling it:
Use like below:
-(void)askForGPSEnable{
[clsCommonFuncDBAdapter alertViewWithYesNo:msgGPSTitle :msgGPSMessage :0 :self];
}
Let me know in case of any difficulty.
You'll need to create your own custom view, and implement some alert view style behaviour, such as displaying modally, dimming the background, animating in and out, etc.
There's no support in the SDK for customising a UIAlertView any further than the text or buttons.
http://iphonedevelopment.blogspot.com/2010/05/custom-alert-views.html
and
http://www.skylarcantu.com/blog/2009/08/14/custom-uialertview-color-chooser/
You can use above links for custom alerts. I hope these will be helpful for you.
There is very good example on Git hub for custom alert view. It is using UI alert view in core and provides number of methods to customize alert view in different ways
