以UIImageView為例

首先繼承系統UIScrollView自定義一個UIScrollView

#import "HWScrollVIew.h"
@implementation HWScrollVIew

// 拖動來(只要這個就可以了)
-(BOOL)touchesShouldCancelInContentView:(UIView *)view{  
    if ([view isKindOfClass:[UIImageView class]]) {      
        return NO;   
 }   
    return YES;
}
@end

外部使用

    HWScrollVIew *scrollV = [[HWScrollVIew alloc]initWithFrame:CGRectMake(0, 0, 320, 600 )];
    scrollV.delaysContentTouches = NO;
    scrollV.canCancelContentTouches = YES;

只要拖動的是HWScrollVIew上的所有UIImageView控件,HWScrollVIew都不會滾動,沖突解決
