好像不适用此场景”结合UIScrollView使用，滑动到最左侧滑出左侧抽屉，滑动到最右侧滑出右侧抽屉“

目前好像不适用此场景”结合UIScrollView使用，滑动到最左侧滑出左侧抽屉，滑动到最右侧滑出右侧抽屉“，也不知道是不是没用对方法😔

在巨人的肩膀上😜，简单修改了下，ps：新人一枚，若改出问题，请原谅😜 1、在WynterW大神基础上修改了UIScrollView方法 `/**

重写手势，如果是左滑，则禁用掉scrollview自带的 */
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer )gestureRecognizer { if([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) { UIPanGestureRecognizer pan = (UIPanGestureRecognizer *)gestureRecognizer; //NSLog(@"%f -- %f", [pan translationInView:self].x, self.contentOffset.x); if([pan translationInView:self].x > 0.0f && self.contentOffset.x == 0.0f) { //NSLog(@"左滑"); return NO; } if ([pan translationInView:self].x < 0.0f && self.contentSize.width - self.contentOffset.x <= self.bounds.size.width) { //NSLog(@"右滑"); return NO; } } return [super gestureRecognizerShouldBegin:gestureRecognizer]; }`

2、参照原有注册手势驱动方法之外添加下面的方法 `/** 注册手势驱动方法，侧滑呼出的方向自动确定，一般在viewDidLoad调用，调用之后会添加一个支持侧滑的手势到本控制器

@param openEdgeGesture 是否开启边缘手势,边缘手势的开始范围为距离边缘50以内 @param transitionDirectionAutoBlock 手势过程中执行的操作。传整个点击present的事件即可（看demo的使用） */

(void)cw_registerShowIntractiveWithEdgeGesture:(BOOL)openEdgeGesture transitionDirectionAutoBlock:(void(^)(CWDrawerTransitionDirection direction))transitionDirectionAutoBlock {

CWLateralSlideAnimator *animator = [CWLateralSlideAnimator lateralSlideAnimatorWithConfiguration:nil]; self.transitioningDelegate = animator;

objc_setAssociatedObject(self, &CWLateralSlideAnimatorKey, animator, OBJC_ASSOCIATION_RETAIN_NONATOMIC);

CWInteractiveTransition *interactiveShow = [CWInteractiveTransition interactiveWithTransitiontype:CWDrawerTransitiontypeShow]; [interactiveShow addPanGestureForViewController:self]; [interactiveShow setValue:@(YES) forKey:@"isAutoDirection"]; [interactiveShow setValue:@(openEdgeGesture) forKey:@"openEdgeGesture"]; [interactiveShow setValue:transitionDirectionAutoBlock forKey:@"transitionDirectionAutoBlock"]; [interactiveShow setValue:@(CWDrawerTransitionDirectionLeft) forKey:@"direction"];

[animator setValue:interactiveShow forKey:@"interactiveShow"]; }`

3、修改CWInteractiveTransition.m文件新增属性 @property (nonatomic, copy) void(^transitionDirectionAutoBlock)(CWDrawerTransitionDirection direction); /* 默认NO */ @property (nonatomic, assign) BOOL isAutoDirection;

修改方法 `- (void)showBeganTranslationX:(CGFloat)x gesture:(UIPanGestureRecognizer *)pan { //NSLog(@"---->%f", x); if (self.isAutoDirection == YES) { if (x >= 0) { _direction = CWDrawerTransitionDirectionLeft; } else { _direction = CWDrawerTransitionDirectionRight; } }

if ((x < 0 && _direction == CWDrawerTransitionDirectionLeft) || (x > 0 && _direction == CWDrawerTransitionDirectionRight)) return;

CGFloat locX = [pan locationInView:_weakVC.view].x;
//    NSLog(@"locX: %f",locX);
if (_openEdgeGesture && ((locX > 50 && _direction == CWDrawerTransitionDirectionLeft) || (locX < CGRectGetWidth(_weakVC.view.frame) - 50 && _direction == CWDrawerTransitionDirectionRight))) {
    return;
}
self.interacting = YES;
if (_transitionBlock) {
    _transitionBlock();
}

if (self.isAutoDirection == YES) {
    if (_transitionDirectionAutoBlock) {
        _transitionDirectionAutoBlock(_direction);
    }
}

}`

4、调用 `- (void)viewDidLoad { [super viewDidLoad];

self.tabBarController.view.backgroundColor = [UIColor whiteColor];

if ([self respondsToSelector:@selector(edgesForExtendedLayout)]) {
    self.edgesForExtendedLayout = UIRectEdgeNone;
}

[self setupNavBarItem];

[self setupScrollView];

// 注册手势驱动
__weak typeof(self)weakSelf = self;
[self cw_registerShowIntractiveWithEdgeGesture:NO transitionDirectionAutoBlock:^(CWDrawerTransitionDirection direction) {
    //NSLog(@"direction = %ld", direction);
    if (direction == CWDrawerTransitionDirectionLeft) {
        [weakSelf leftClick];
    } else if (direction == CWDrawerTransitionDirectionRight) {
        [weakSelf rightClick];
    }
}];

// [self cw_registerShowIntractiveWithEdgeGesture:NO direction:CWDrawerTransitionDirectionLeft transitionBlock:^{ // [weakSelf leftClick]; // }];

// [self cw_registerShowIntractiveWithEdgeGesture:NO direction:CWDrawerTransitionDirectionRight transitionBlock:^{ // [weakSelf rightClick]; // }];

}`
