將按鈕添加到工具欄

Question

我需要添加一個透明的工具欄，並添加4個圖像的按鈕。我怎樣才能通過代碼做到這一點？

我的工作到目前爲止;

我已添加工具欄，並使其透明 現在我正試圖添加4個按鈕的圖像。我怎樣才能做到這一點 ？ （這4個按鍵也有action方法，所以當一個人點擊它的動作應該火起來）

toolBar1 = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 320 , 320 , 60)]; 

[toolBar1 setBarStyle:UIBarStyleBlack]; 

[toolBar1 setTranslucent:YES]; 

NSMutableArray* allthebuttons = [[NSMutableArray alloc] initWithCapacity:4]; 

UIBarButtonItem *buttonWithImage = [[UIBarButtonItem alloc] ...... // Now what ?? 

[self.view addSubview:toolBar1]; 

Answer 1

NSMutableArray *buttonsArray = [[NSMutableArray alloc] init]; 
UIBarButtonItem *myButton1=[[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"email.png"] style:UIBarButtonItemStylePlain target:self action:@selector(toolbarButtonPressed1:)]; 
[buttonsArray addObject:myButton1]; 
UIBarButtonItem *myButton2 = [[UIBarButtonItem alloc] initWithTitle:@"button 2" style:UIBarButtonItemStylePlain target:self action:@selector(toolbarButtonPressed2:)]; 
[buttonsArray addObject:myButton2]; 
[self setToolbarItems:buttonsArray animated:YES]; 

請注意，對於上述，您需要使用導航視圖控制器上的工具欄。

Answer 2

UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:@"Item" style:UIBarButtonItemStyleBordered target:self action:@selector(action]; 

UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:@"Item1" style:UIBarButtonItemStyleBordered target:self action:@selector(action]; 

NSArray *buttons = [NSArray arrayWithObjects: item1, item2, nil]; 
[toolBar setItems: buttons animated:NO]; 

[item1 release]; 
[item2 release]; 

只是對上面的代碼爲4個按鈕

更新1：

使用下面的代碼獲取圖像按鈕

UIImageView *btn1Img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Btn1Img"]]; 

UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithCustomView:btn1Img];
