遵守代理UIGestureRecognizerDelegate

-(void)setUpLeftView{

    // 屏幕边缘侧拉手势
    UIScreenEdgePanGestureRecognizer *edgeGesture = [[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(handleGesture:)];
    edgeGesture.edges = UIRectEdgeLeft;
    edgeGesture.delegate = self;
    [self.view addGestureRecognizer:edgeGesture];
}
- (void)handleGesture:(UIScreenEdgePanGestureRecognizer *)gesture
{
    if(UIGestureRecognizerStateBegan == gesture.state)
    {
        // 根据被触摸手势的view计算得出坐标值
        CGPoint translation = [gesture translationInView:gesture.view];
        NSLog(@"%@",NSStringFromCGPoint(translation));
    }
    else
    {
        //
        NSLog(@"恢复设置");
    }
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    if ([gestureRecognizer isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]) {
        return YES;
    }
    return NO;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    if ([gestureRecognizer isKindOfClass:[UIScreenEdgePanGestureRecognizer class]]) {
        return YES;
    }
    return NO;
