我需要建立一個自定義的UIBarButton。我所做的大部分工作除了我無法獲得我的按鈕的顏色以匹配iPhone UIBarButton。我怎麼能匹配它？需要顏色來建立一個自定義的UIButton放在UIBarButton裏面
以下是我有：（主要來自要素樣本項目撕開）
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];
