將圖像和標題添加到導航backBarButtonItem

Question

我試圖添加一個圖標（並保留標題）到我的導航控制器的後退按鈕。看來如果我設置UIBarButtonItem的圖像，它隱藏了標題，所以我想我會嘗試一個自定義視圖。我試過

UIButton* customButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
[customButton setImage:[UIImage imageNamed:@"icon"] forState:UIControlStateNormal]; 
[customButton setTitle:@"Title" forState:UIControlStateNormal]; 
[customButton setAdjustsImageWhenHighlighted:YES]; 
[customButton setFrame:CGRectMake(0, 0, 125, 32)]; 

UIBarButtonItem* backButton = [[UIBarButtonItem alloc] initWithCustomView:customButton]; 
self.navigationItem.backBarButtonItem = backButton; 

但蘋果文檔說backBarButtonItem忽略自定義視圖，所以這是行不通的。

我也試過這樣：

self.navigationItem.leftBarButtonItem = backButton; 
self.navigationItem.hidesBackButton = YES; 

但leftBarButtonItem太早顯示出來一個屏幕和hidesBackButton似乎並沒有隱藏backBarButtonItem。

有沒有另一種方式來同時獲得圖像和標題導航backBarButtonItem？

Answer 1

第一個由susing代碼self.navigationItem.hidesBackButton = YES;

隱藏由UINavigationController提供的後退按鈕，並用圖像和標題設置自己的按鈕用下面的代碼

UIButton* customButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
[customButton setImage:[UIImage imageNamed:@"icon"] forState:UIControlStateNormal]; 
[customButton setTitle:@"Title" forState:UIControlStateNormal]; 
[customButton setAdjustsImageWhenHighlighted:YES]; 
[customButton setFrame:CGRectMake(0, 0, 125, 32)]; 

UIBarButtonItem* backButton = [[UIBarButtonItem alloc] initWithCustomView:customButton]; 
self.navigationItem.backBarButtonItem = backButton;
