UIView on UIView and UIButton not work

Question

UIView *background = [[UIView alloc] initWithFrame:self.view.bounds];
background.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height-70);
[self.view addSubview:background];

UIView *background2 = [[UIView alloc] initWithFrame:CGRectMake(10, self.view.bounds.size.height-60, 300, 50)];
background2.backgroundColor = [UIColor whiteColor];
background2.layer.cornerRadius = 8;
background2.layer.masksToBounds = YES;
[background addSubview:background2];


UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 158, 50);
[button setTitle:@"myButton" forState:UIControlStateNormal];
[button addTarget:self action:@selector(myButton:) forControlEvents:UIControlEventTouchUpInside];
[background2 addSubview:button];

button does not respond to touch? Why?

Answer 1

background.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height-70);


 UIView *background2 = [[UIView alloc] initWithFrame:CGRectMake(10, self.view.bounds.size.height-60, 300, 50)];

self.view.bounds.size.height-70 compare this self.view.bounds.size.height-60 background2 out of frame of background frame

set your background frame self.view.bounds.size.height now it will perfectly works

Answer 2

Your code works fine, I just tried it. I only changed the frame of background2 to not be outside of the frame of background .
