Navigationbar

返回问题

1.更改默认返回键图标-如果想只显示图标的话，文字改为空字符串即可

  [self.navigationController.navigationBar setBackIndicatorImage:img];
  [self.navigationController.navigationBar setBackIndicatorTransitionMaskImage:img];
  UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStylePlain target:nil action:nil];

2.设置侧滑返回

在基础类中进行如下设置

  if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
      self.navigationController.interactivePopGestureRecognizer.delegate = self;
      }
