這是scrollView左右滑動(dòng)與側(cè)滑手勢(shì)沖突解決方法。
其實(shí)就是判斷手勢(shì)是否繼續(xù)向下傳遞。

1.當(dāng)然要自定義一個(gè)UIScrollView，在CustomScrollView的手勢(shì)代理方法里實(shí)現(xiàn)自己的邏輯

#import "CustomScrollView.h"


@interface CustomScrollView()

@property(nonatomic,assign)BOOL isMoveRight;

@end

@implementation CustomScrollView


//1返回值是返回是否生效。此方法在gesture recognizer視圖轉(zhuǎn)出UIGestureRecognizerStatePossible狀態(tài)時(shí)調(diào)用，如果返回NO,則轉(zhuǎn)換到UIGestureRecognizerStateFailed;如果返回YES,則繼續(xù)識(shí)別觸摸序列
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{

    //滑動(dòng)速度
    CGPoint velocity = [(UIPanGestureRecognizer *)gestureRecognizer velocityInView:self];
    
    CGPoint location = [gestureRecognizer locationInView:self];
    
    NSLog(@"velocity.x:%f----location.x:%d",velocity.x,(int)location.x%(int)[UIScreen mainScreen].bounds.size.width);
    
    //x方向速度>0為右滑動(dòng)，反之為左滑動(dòng)
    if (velocity.x > 0) {
        
        self.isMoveRight = YES;
        
    }else{
        
        self.isMoveRight = NO;
    }
    
    return YES;

}



//2
//此方法返回YES時(shí)，手勢(shì)事件會(huì)一直往下傳遞(允許多手勢(shì)觸發(fā))，不論當(dāng)前層次是否對(duì)該事件進(jìn)行響應(yīng)。
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    
    
    UIScrollView * scrollvire = (UIScrollView *)gestureRecognizer.view;
    
    //根據(jù)contentOffset.x 與 滑動(dòng)方向 來(lái)判斷手勢(shì)是否向下傳遞
    if (scrollvire.contentOffset.x == 0 && self.isMoveRight == YES) {
        
        return YES;
    }
    
    return NO;
   
}
