这是一个ViewControllerA
push a ViewControllerB
,并且在 theViewControllerB
中leftBarButtonItem
设置如下:
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(backBtnClicked:)];
设置后leftBarButtonItem
,后退滑动手势不起作用。是否可以保持滑动手势?
