- (UIViewController *)popViewControllerAnimated:(BOOL)animated 

[self.navigationController popViewControllerAnimated: YES] 

創建一個按鈕，添加一個動作將其

[button addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside]; 

然後創建back方法

-(void)back:(id)sender 
{ 
    [self.navigationController popViewControllerAnimated: YES] 
} 

Answer 2

[self.navigationController popViewControllerAnimated: YES] 

如果你想使用按鈕，添加一個按鈕，並設置其操作處理程序來調用該方法。 例如你有

UIButton *backButton; 

，並設置其行動，

[backButton addTarget:self action:@selector(didPressBackButton) 
forControlEvents:UIControlEventTouchUpInside 

然後，

- (void) didPressBackButton { 
[self.navigationController popViewControllerAnimated: YES] 
} 

Answer 3

您可以創建自定義buttoin和下面的代碼添加到其方法調用。

[self.navigationController popViewControllerAnimated：YES];
