从单独的类调用静态方法的选择器

Question

假设我想创建以下手势识别器

UITapGestureRecognizer * c1 = [[UITapGestureRecognizer alloc] 
          initWithTarget:self 
          action:@selector([[MyGestureRecognizer ViewWasClicked1:]]; // error 
[c1 setNumberOfTapsRequired:1];
[c1 setNumberOfTouchesRequired:1];
[[self view] addGestureRecognizer:c1];

但我想在一个单独的类上调用选择器.我有方法:

+ (void)ViewWasClicked1:(UITapGestureRecognizer *)sender {    

    NSLog(@"click1 mouse down");

}

在MyGestureRecognizer类中.我可以找到什么？

Answer 1

语法是:

UITapGestureRecognizer * c1 = [[UITapGestureRecognizer alloc] 
      initWithTarget:[MyGestureRecognizer class]
      action:@selector(ViewWasClicked1:)]; // error
