Answer 1

您可以使用手势识别器:

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

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

Answer 2

默认情况下,UILabel未配置为接受触摸输入.但是,如果您使用UIButton而不是将其设置为具有自定义外观,则可以使其看起来像(单行)标签并让它响应触摸事件.
