我已经添加了工具栏并使其透明，现在我正在尝试添加 4 个带有图像的按钮。我怎样才能做到这一点 ？（这 4 个按钮也应该有一个action方法，所以当一个人点击它时，一个动作应该被触发）
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];

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];

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];
Note, for the above you'll want to use the toolbar on the navigation view controller.
请注意，对于上述情况，您需要使用导航视图控制器上的工具栏。
