是否可以检测按钮的触摸？

Question

我有一个应用程序，我想检测按钮上的触摸，如第一次触摸，第二次触摸。有可能吗？

Answer 1

这是一种方法..

UIButton *sampleButton = [UIButton buttonWithType:UIButtonTypeCustom];
[sampleButton setFrame:CGRectMake(100, 100, 100, 52)];
[sampleButton setTitle:@"Button Title" forState:UIControlStateNormal];
[sampleButton setFont:[UIFont boldSystemFontOfSize:20]];
[sampleButton setBackgroundImage:[[UIImage imageNamed:@"redButton.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];
[sampleButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:sampleButton];

然后在方法buttonPressed中你可以计算出触摸

-(void)buttonPressed
{
   touchCount++;
   // Do something or not
}

Answer 2

只计算变量中的触摸事件。
