需要顏色來構建自定義UIButton以便放置在UIBarButton中

Question

我需要構建一個自定義UIBarButton。 除了無法獲得與iPhone UIBarButton匹配的按鈕顏色之外，我所做的大部分工作都可以正常工作。 我該如何搭配？

這是我所擁有的：（主要是從Elements示例項目中提取的）

UIButton *localFlipIndicator=[[UIButton alloc] initWithFrame:CGRectMake(0,0,50,28)];
self.flipIndicatorButton=localFlipIndicator;
[flipIndicatorButton.titleLabel setFont:[UIFont systemFontOfSize:13]];
flipIndicatorButton.layer.cornerRadius=8.0;
flipIndicatorButton.layer.borderWidth=0.5;

[localFlipIndicator release];

[flipIndicatorButton setTitle:@"Back" forState:UIControlStateNormal];

UIBarButtonItem *flipButtonBarItem;
flipButtonBarItem=[[UIBarButtonItem alloc] initWithCustomView:flipIndicatorButton];
style:UIBarButtonItemStylePlain target:self action:@selector(flipCurrentView)];

[self.navigationItem setRightBarButtonItem:flipButtonBarItem animated:YES];

[flipButtonBarItem release];
