[iOS Dev] UIScrollView的touchesBegan和touchesEnd
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
|
1
2
|
@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];
