問題描述
我的 UIScrollView 有很多子視圖.當(dāng)我滾動(dòng)時(shí)，我想點(diǎn)擊要拖動(dòng)的子視圖.有沒有辦法讓 UIScrollView 停止吞咽觸摸?或者當(dāng)您取消滾動(dòng)時(shí)是否可以開始新的觸摸(就像它滾動(dòng)并且我點(diǎn)擊它一樣，子視圖也會(huì)被點(diǎn)擊以便我可以將其拖出)?
I have UIScrollView that has many subviews. When I scroll, I want to tap on a subview which I want to be dragged. Is there a possible way to make the UIScrollView stop from swallowing touches? Or is it possible to start new touch when you cancel the scrolling (like what it scrolls and I tapped on it, the subview will be tapped as well so I can drag it out)?
推薦答案
繼承 UIScrollView 并覆蓋 - (BOOL)touchesShouldCancelInContentView:(UIView *)view 方法.這是一個(gè)允許 uibutton 觸摸通過的示例:
Subclass UIScrollView and override the - (BOOL)touchesShouldCancelInContentView:(UIView *)view method. Here's an example to allow uibutton touches to pass through:
#import "scrollViewWithButtons.h"
@implementation scrollViewWithButtons
- (BOOL)touchesShouldCancelInContentView:(UIView *)view
{
return ![view isKindOfClass:[UISlider class]];
}
@end
