How to remove subviews in Objective-C?

Question

I have added UIButton and UITextView as subviews to my view programmatically.

notesDescriptionView = [[UIView alloc]initWithFrame:CGRectMake(0,0,320,460)]; notesDescriptionView.backgroundColor = [UIColor redColor]; [self.view addSubview:notesDescriptionView];  textView = [[UITextView alloc] initWithFrame:CGRectMake(0,0,320,420)];  [self.view addSubview:textView];  printf("\n description  button \n");  button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button   addTarget:self action:@selector(cancel:)   forControlEvents:UIControlEventTouchDown]; [button setTitle:@"OK" forState:UIControlStateNormal]; button.frame = CGRectMake(80.0, 420.0, 160.0, 40.0); [self.view addSubview:button]; 

I need to remove all subviews when the button is clicked.

I have tried:

[self.view removeFromSuperView] 

but it's not working.

Answer 1

to remove all the subviews you added to the view

use the following code

for (UIView *view in [self.view subviews])  {     [view removeFromSuperview]; }
