多个 UIView 上的 UITapGestureRecognizer（滚动视图子视图）

Question

我设置了一个滚动视图和一个带有手势的 UIView（滚动视图子视图）长凳：

  for (id element in array) {

        CustomView *view = [[CustomView alloc] init];
        [view setFrame:CGRectMake(x, 16, self.view.frame.size.width, self.view.frame.size.height)];
        [self.scrollView setContentSize:CGSizeMake(scrollContentSizeWidth, self.scrollView.frame.size.height)];
        UITapGestureRecognizer *tap =
        [[UITapGestureRecognizer alloc] initWithTarget:self
                                                action:@selector(selectView:)];
        [self.view setTag:[[element valueForKey:@"Id"] integerValue]];
        [self.view addGestureRecognizer:tap];
        view.userInteractionEnabled = YES;
        [self.scrollView addSubview:view];
        scrollContentSizeWidth +=110;
        x += 110;
    }

视图被触摸时调用的方法：

-(void)selectView:(UITapGestureRecognizer *)recognizer{

    NSLog(@"id : %i",recognizer.view.tag);//always last assigned value in the loop above

}

那么如何解决呢？ UITapGestureRecognizer 似乎只影响到最后一个视图。

Answer 1

替换这一行

[self.view addGestureRecognizer:tap];

有了这个

 [view addGestureRecognizer:tap];
