如何使一个UIButton删除自己

Question

所以这是我的代码：

for (int x = 1; x < 100; x++) { 
     int randomX = arc4random() %280; 
     int randomY = arc4random() %500; 

     UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
     [myButton setTitle:string forState:UIControlStateNormal]; 
     myButton.frame = CGRectMake(randomX, randomY, 40.0, 40.0); 
     [myButton addTarget:self action:@selector(buttonUp) forControlEvents:UIControlEventTouchUpInside]; 

     [self.view addSubview:myButton]; 

如何使按钮删除自己的时候放手？

Answer 1

更改选择器

@selector(buttonUp:) 

然后在你的方法定义

- (void)buttonUp:(UIButton*)sender 

添加

[sender removeFromSuperview]
