大家好，又见面了，我是你们的朋友全栈君。
touchesBegan 跟 touchedEnd 沒有提供給 UIScrollViewDelegate
所以要自己建立一個繼承自 UIScrollView 的 class
重寫這兩個 method
myScrollView.h
@interface myScrollView : UIScrollView
@end
myScrollView.m
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[super touchesBegan:touches withEvent:event];
if ( !self.dragging )
{
[[self nextResponder] touchesBegan:touches withEvent:event];
}
}
-(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
[super touchesEnded:touches withEvent:event];
if ( !self.dragging )
{
[[self nextResponder] touchesEnded:touches withEvent:event];
}
}
之後建立 UIScrollView 就是用 myScrollView 建立 即可使用這兩個 method
myScrollView *contentScrollView = [[myScrollView alloc] init];
