UIScrollView中的UIButton不会点亮 [英] UIButton inside UIScrollView doesn't fire on tap

问题描述

UIScrollView中的UIButton无法点击。请帮忙解决它。

UIButton inside UIScrollView doesn't fire on tap. Please help resolve it.

 // Add a button
 UIButton *btn1 = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
 btn1.frame = CGRectMake(0, 0, 26, 18); 
 btn1.bounds = CGRectMake(0, 0, 30.0, 30.0); 
 [btn1 addTarget:self action:@selector(buttonClick1:) 
                      forControlEvents:UIControlEventTouchUpInside];
 [scrollView addSubview:btn1];


- (void)buttonClick1:(id)sender {
     int dd = 4; 
 }

推荐答案

我找到了这个东西：

但是除非你设置
userInteractionEnabled和
exclusiveTouch属性，否则scrollview将阻止按钮的
触摸在
滚动视图中为NO。但是这会打败我认为在
a按钮内设置滚动视图的
目的。

But the scrollview will block the touches from the button unless you set userInteractionEnabled and exclusiveTouch properties to NO on the scrollview. But that would defeat the purpose of having a scrollview inside a button I think.

（参见我们可以在UIScrollView中放置一个UIButton反之亦然iPhone ）

但该怎么办？

假设你有一个UIScrollView * sv ... then

Say you have a UIScrollView *sv ... then

sv.userInteractionEnabled = YES;
sv.exclusiveTouch = YES;

我还要添加

sv.canCancelContentTouches = YES;
sv.delaysContentTouches = YES;
