當(dāng)MMDrawerController的centerViewController添加UIScrollView的時候，滑動打開抽屜就失效了。我在網(wǎng)上找到這篇帖子https://www.2cto.com/kf/201608/543321.html跟我的問題類似，雖然我使用他的方法并沒有奏效，不過按照他的思路我最終還是解決了我的問題。

解決辦法是寫一個UIScrollView的子類，并實現(xiàn)UIGestureRecognizerDelegate中的方法

@implementation CJScrollView

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer*)gestureRecognizer {

    if([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
        return YES;
    }
    return [super gestureRecognizerShouldBegin:gestureRecognizer];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizer {

    if ([gestureRecognizer isKindOfClass:NSClassFromString(@"UIScrollViewPanGestureRecognizer")] &&
        [otherGestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {

        if(self.contentOffset.x==0.0f) {
            //這里返回YES，gestureRecognizer和otherGestureRecognizer互斥時，gestureRecognizer會失效
            return YES;
        }
    }
    return NO;
}
