修改返回按鈕
//修改導航條背景色（紅褐色）
self.navigationController.navigationBar.barTintColor = RGB(175, 24, 50, 1.0);
其中RGB為我的工程里的一個宏定義:
#define RGB(r,g,b,a) [UIColor colorWithRed:(r/255.0) green:(g/255.0) blue:(b/255.0) alpha:(a)]
//修改導航條標題顏色（白色）
[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,nil]];
//修改導航條添加的按鈕（item）顏色(黃色)
self.navigationController.navigationBar.tintColor = [UIColor yellowColor];
需要注意一點: 這個設置完成之后殿衰，從他push過去的頁面顏色都是這種效果朱庆。
