I have added a UIView and now, i want to show a UILabel. However, it does not get displayed. Can someone help me out please ?
- (IBAction)infoButtonClicked:(id)sender {

myView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(5, 10, self.view.frame.size.width, 100)];
[myView addSubview:label];
[self.view addSubview: myView];

I wanted to have a blurred background and view popups in my application. But blur background and view is not appearing when I clicked my button.... can anyone please help me to achieve this task...
My codes are
- (IBAction)ButtonTouched:(id)sender {
if(!UIAccessibilityIsReduceTransparencyEnabled()){
self.view.backgroundColor = [UIColor clearColor];
UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
UIVisualEffectView *blureffectview = [[UIVisualEffectView alloc]initWithEffect:blurEffect];
blureffectview.frame = self.view.bounds;
blureffectview.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
//[self.view addSubview:blureffectview];
[self.view insertSubview:_AnimatedViewForLoading aboveSubview:blureffectview];
}else{
//self.view.backgroundColor = [UIColor blackColor];
}
UIView * AnimatedViewForLoading;
// [[UIView alloc] initWithFrame:CGRectMake(118, 318, 200, 150)];
self.AnimatedViewForLoading.frame = CGRectMake(118, 318, 200, 150);

} completion:^(BOOL finished) {
NSLog(#"oopssssss..........");
[UIView animateWithDuration:0.3/2 animations:^{
self.AnimatedViewForLoading.transform = CGAffineTransformIdentity;
}];
}];
}
Problem
Why doesn't blur background appear? - Because you didn't add it to self.view
//[self.view addSubview:blureffectview];
Why doesn't AnimatedViewForLoading appear? - Because you added it to self.view before it's initialized and self.AnimatedViewForLoading.alpha is set to 0.0f
// self.AnimatedViewForLoading is hidden at this line
self.AnimatedViewForLoading.alpha = 0.0f;
// |_AnimatedViewForLoading| is initialized after this line
[self.view insertSubview:_AnimatedViewForLoading aboveSubview:blureffectview];
Solution

I've done this a million times before but finding myself confused now.
When you animate a container view to change its position, its subviews move along with it don't they? You don't change subviews' frames you just change superview's frame because all subviews' positions inside their superview don't change.
But for some reason this time the subviews would not move along with their superview, it'd stay stuck at its original position.

I'm setting up a subclass of UIView to roll my own UIAlertView style view. I've got everything set up properly with displaying the view, but I'm at a bit of a loss as to how to dismiss the view properly. Specifically, when a user taps on the button in the view, it needs to animate out of the main view. This is the code for the view itself:

When button1 is tapped, for instance, I need to have it animate the view out of the superView and remove it from the stack. I'm not sure how to handle this. Does anyone have any ideas?
To permanently remove a view, I generally use the UIView instance method removeFromSuperview. followed by a line setting the relevant variable to nil:
[myAlertView removeFromSuperview];
myAlertView = nil;
In your case then, I think you need to move the view off the screen by animating the its bounds property, then use the above couple of lines to remove any references to it.
Just found the answer here:
Dismiss view controller from #selector without creating seperate method
Had to download some custom classes but it worked:
[button1 addEventHandler:^(id sender, UIEvent *event)
{
[UIView animateWithDuration:0.25f animations:^{
[alertBackground setAlpha:0.0f];
[shadeWindow setAlpha:0.0f];
[window setAlpha:0.0f];
}];
} forControlEvent:UIControlEventTouchUpInside];
Custom classes can be found here:

I've looked all over Google & Stack Overflow, but I haven't found one clear answer. How do I switch to the TOCViewController after tapping the UIButton? I'm currently using "presentViewController" but it just freezes on tapping the button. Thanks in advance for any help.

I copy-pasted your code into a file and found a warning on this line [tos addTarget:self action:#selector(displayTOC:) forControlEvents:UIControlEventTouchUpInside]; The warning says,
Undeclared selector 'displayTOC:'
When I ran the code and tapped the TOC button, it didn't just freeze, it crashed with the error:
-[ViewController displayTOC:]: unrecognized selector sent to instance ...
These should be strong hints on what is wrong in your code. When you ask people about your code, you should reveal any and all warnings, and crashes.
Note, a method named displayTOC is not the same as a method named displayTOC:
By the way, the animation you did is really cool. Good job!
I am trying to implement ,long press and delete functionality of apple, myself.
