UIView on UIView和UIButton不工作

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];

按钮不响应触摸？为什么？

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比较背景帧外的self.view.bounds.size.height-60 background2

设置您的背景框架self.view.bounds.size.height，现在它将完美地工作

Answer 2

你的代码很好，我刚试过了。我只更改了background2的框架，使其不超出background的框架。
