UILabel有触摸方法吗？ [英] Is there a touch method for UILabel?

问题描述

如果有人碰到预先声明的 UILabel ，我想采取行动：

I'd like to do an action if someone touches a predeclared UILabel, something like:

if (label is touched) {
    my actions;
}

是否有方法/方法？

推荐答案

您可以使用手势识别器：

You could use a gesture recognizer:

- (void)someSetupMethod {
    // ...
    label.userInteractionEnabled = YES;
    UITapGestureRecognizer *tapGesture = \
    [[UITapGestureRecognizer alloc]
     initWithTarget:self action:@selector(didTapLabelWithGesture:)];
    [label addGestureRecognizer:tapGesture];
    [tapGesture release];
}

- (void)didTapLabelWithGesture:(UITapGestureRecognizer *)tapGesture {
    // ...
}
