1.

1：@property MyScrollView *scrollView;

2：给MyScrollView，增加类别：MyScrollView+Touch

3：在类别里实现下面三个方法：

@implementation MyScrollView (Touch)

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

[[self nextResponder] touchesBegan:touches withEvent:event];

[super touchesBegan:touches withEvent:event];

}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {

[[self nextResponder] touchesMoved:touches withEvent:event];

[super touchesMoved:touches withEvent:event];

}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

[[self nextResponder] touchesEnded:touches withEvent:event];

[super touchesEnded:touches withEvent:event];

}

@end

4：- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{

[self hiddenkeyBoard];

}
