隱藏導航欄上的后退按鈕是iOS6

Question

要隱藏后退按鈕導航欄，我嘗試了以下所有語句，但沒有一個適合我

[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

嘗試這個，

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

Answer 2

嘗試這個：

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

Answer 3

嘗試查看您的第5條聲明，您已設置為“否”，因此請對其進行更改。

 self.navigationItem.hidesBackButton = YES; //5
