Animated UIButton not registering press - ios

Question

I am trying to make a slide out notification bar for when the app receives a notification and the app is currently open and in the foreground. I got this working with a custom UIView (actually it's a UIButton) and an animation. For some reason though it won't register a press when I tap on it. It won't call the selector method. Code is below:
-(void)appOpenPush {
//get string
NSLog(#"got a push while app was open");
AppDelegate *appDelegate =(AppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *pushString = appDelegate.pushString;
//play sound
AudioServicesPlaySystemSound(MessageSound);
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
//note I am actually using a button here
UIButton *pushView =[[UIButton alloc] initWithFrame:CGRectMake(0, -75, [[UIScreen mainScreen] bounds].size.width,75)];
pushView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.8];
[pushView addTarget:self action:#selector(pushSlidePress) forControlEvents:UIControlEventTouchUpInside];
//set image
UIImageView *logo = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"icon120.png"]];
logo.frame=CGRectMake(5, 20, 35, 35);
logo.layer.cornerRadius=8;
logo.clipsToBounds=YES;
[pushView addSubview:logo];
UILabel *pushLabel = [[UILabel alloc] initWithFrame:CGRectMake(48, 34, 0, 0)];
pushLabel.text=pushString;
pushLabel.font=[UIFont systemFontOfSize:13];
[pushLabel sizeToFit];
pushLabel.textColor=[UIColor whiteColor];
[pushView addSubview:pushLabel];
//animate
UIWindow* currentWindow = [UIApplication sharedApplication].keyWindow;
[currentWindow addSubview:pushView];
[UIView animateWithDuration:0.4 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
pushView.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.4 delay:2.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
pushView.frame = CGRectMake(0, -75, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[pushView removeFromSuperview];
}];
}];
}
Could anyone give me a pointer to why this isn't working? Is it because I am adding the UIButton to the main window? Any tips would be really helpful. thanks!

Answer 1

You have to add UIViewAnimationOptionAllowUserInteraction as an option to both of your animation blocks.
As per the documentation :
"Allow the user to interact with views while they are being animated."

Answer 2

Try this to avoid logo and pushLabel receive touches events:
logo.userInteractionEnabled = NO;
pushLabel.userInteractionEnabled = NO;

Answer 3

So it turns out you can't simply detect a press if the button is moving. I tested this by just adding the frame setup without it animating and it registered the press, when animation is turned on it doesn't. Seems that UIButton doesn't have tracking built in. I did come up with a quick fix. I just made a button the same size as the total animation area (i.e. the size of my slide out bar) and added that to the currentWindow on top of the animation frame. So it's just a clear invisible button on top of the animation but it's not moving itself. i.e:
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0,[[UIScreen mainScreen]bounds].size.width , 75)];
[button addTarget:self action:#selector(pushSlidePress) forControlEvents:UIControlEventTouchUpInside];
[currentWindow addSubview:button];
[UIView animateWithDuration:0.4 delay:0.0 options:(UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction) animations:^{
pushView.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.4 delay:2.0 options:(UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction) animations:^{
pushView.frame = CGRectMake(0, -75, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[pushView removeFromSuperview];
[button removeFromSuperview];
}];
}];
Obviously you are covering an area of the screen that might block other things being pressed, but it depends on your setup. The animation is quick and I only have one button that the notification bar will block and it's too quick to notice. Hopefully this will be helpful to someone else trying to achieve a similar thing. Thanks for your help guys.
