隐藏导航栏上的后退按钮是iOS6

Question

要隐藏后退按钮导航栏，我尝试了以下所有语句，但没有一个适合我

[self.navigationController.navigationItem setHidesBackButton:YES]; //1
[self.navigationController.navigationBar.backItem setHidesBackButton:YES]; //2
self.navigationController.navigationItem.hidesBackButton = TRUE;  //3
[self.navigationItem setHidesBackButton:YES animated:YES]; //4
 self.navigationItem.hidesBackButton = NO; //5

Answer 1

尝试这个，

- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.leftBarButtonItem=nil;
self.navigationItem.hidesBackButton=YES;
}

Answer 2

尝试这个：

[self.navigationController.topViewController.navigationItem setHidesBackButton:YES];

Answer 3

尝试查看您的第5条声明，您已设置为“否”，因此请对其进行更改。

 self.navigationItem.hidesBackButton = YES; //5
