UIBarButtonItem * backItem = [[UIBarButtonItemalloc]init];

backItem.title =@"";

self.navigationItem.backBarButtonItem = backItem;

[selfpushViewController:forgetSecretVCanimated:YES];

直接再跳转的时候设置下个界面的title也是一个好方法会减少对手势的操作

侧滑问题是解决了但是遇到的就是手势冲突的问题,手势代理方法有多个

@protocol UIGestureRecognizerDelegate <NSObject>

@optional

//开始进行手势识别时调用的方法，返回NO则结束，不再触发手势

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

//是否支持多时候触发，返回YES，则可以多个手势一起触发方法，返回NO则为互斥

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;

//下面这个两个方法也是用来控制手势的互斥执行的

//这个方法返回YES，第一个手势和第二个互斥时，第一个会失效

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer NS_AVAILABLE_IOS(7_0);

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer NS_AVAILABLE_IOS(7_0);

//在上面两个方法之前调用

//手指触摸屏幕后回调的方法，返回NO则不再进行手势识别，方法触发等

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch;

// called before pressesBegan:withEvent: is called on the gesture recognizer for a new press. return NO to prevent the gesture recognizer from seeing this press

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceivePress:(UIPress *)press;

@end
