从一个界面push到下一界面左上角返回按钮文字设置

在父viewController中如下设置：

UIBarButtonItem*backbutton = [[UIBarButtonItem alloc]init];

backbutton.title= @"返回列表";

self.navigationItem.backBarButtonItem=backbutton;

navigationbar的back键触发其他事件

UIButton*back =[[UIButton alloc] initWithFrame:CGRectMake(200, 25, 63,30)];

[back addTarget:selfaction:@selector(reloadRowData:)forControlEvents:UIControlEventTouchUpInside];

[back setImage:[UIImageimageNamed:@"返回按钮.png"] forState:UIControlStateNormal];

UIBarButtonItem*backButtonItem = [[UIBarButtonItem alloc]initWithCustomView:back];

self.navigationItem.leftBarButtonItem=loginButtonItem

UINavigationControll采用pushViewController后如何去掉左边的返回按钮

UIBarButtonItem *temporaryBarButtonItem = [[UIBarButtonItemalloc] init];

temporaryBarButtonItem.title= @"";

self.navigationItem.backBarButtonItem= temporaryBarButtonItem;

[temporaryBarButtonItemrelease];

或者self.navigationItem.hidesBackButton = YES;前者在主视图中，后者在子视图中用

push后隐藏返回按钮

push后隐藏返回按钮 self.navigationItem.hidesBackButton = YES;

push后隐藏底部条 viewController.hidesBottomBarWhenPushed = YES; 或者self.tabBarController.tabBar.hidden = YES;
