A recent project contained an embedded game and had this issue: swiping left made the navigation bar and tabbar appear. That led to the code below.

The code is as follows

Core code

// 禁用返回手势,需要开启只需设置为yes即可。默认开启  

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {  
self.navigationController.interactivePopGestureRecognizer.enabled = NO;  
}
