隐藏导航栏上的后退按钮是iOS6

想要隐藏“后退”按钮导航栏，我尝试了以下所有语句，但没有一个对我有效

[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

试试这个

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

试试这个：

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

---

试着看看你的第五句话，你已经设置了否，所以请改变它。它会很好的工作

 self.navigationItem.hidesBackButton = YES; //5
