關於手勢 — 手勢添加tag值

當我們定義了多個手勢得時候，就需要對收拾做一些區分，當然不區分，每個手勢定義一個方法名也是可以的，就是麻煩，所以···

通常我們是給控件加tag值來區分的，當然，手勢沒有自帶的tag屬性，但是手勢所屬的view具有tag屬性， 

 UITapGestureRecognizer *tapGeture1 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(buttonJump:)];
    tapGeture1.delegate = self;
    [_bView1 addGestureRecognizer:tapGeture1];
    UIView *tapView1 = [tapGeture1 view];
    tapView1.tag = 151;
    
    UITapGestureRecognizer *tapGeture3 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(buttonJump:)];
    tapGeture3.delegate = self;
    [_bView3 addGestureRecognizer:tapGeture3];
    UIView *tapView3 = [tapGeture3 view];
    tapView3.tag = 153;

手勢方法中實現如下

- (void)buttonJump:(UITapGestureRecognizer *)tapGesture{

    UITapGestureRecognizer *singleTap = (UITapGestureRecognizer *)tapGesture;
    NSInteger index = singleTap.view.tag;
    switch (index) {
        case 151:{
            ActivitySignUpViewController *actSignUpVC = [[ActivitySignUpViewController alloc]initWithNibName:@"ActivitySignUpViewController" bundle:[NSBundle mainBundle]];
            [self.navigationController pushViewController:actSignUpVC animated:YES];
            break;
        }
        default:
            break;
    }
}
