iOS-更改UINavigationBar樣式+更改返回ButtonItem文字

iOS7之後. 預設的返回按鈕字型顏色是藍色的, 顯示內如是父VC(上一級介面)的title
如果要做修改, 可以通過下面的辦法:

修改字型顏色

(1) 在plist裡面, 加上View controller-based status bar appearance, 並且設定為NO

(2) 在需要修改的那個介面. 加入如下代碼(加在viewDIdLoad即可)<喎?http://www.bkjia.com/kf/ware/vc/" target="_blank" class="keylink">vcD4NCjxwcmUgY2xhc3M9"brush:java;">self.navigationController.navigationBar.barStyle = UIStatusBarStyleDefault;[self.navigationController.navigationBar setTintColor:[UIColor greenColor]];

或:

//Nav樣式    application.statusBarStyle = UIStatusBarStyleLightContent;    [UINavigationBar appearance].barTintColor =[UIColor colorWithRed:24/255.0 green:30/255.0 blue:43/255.0 alpha:1.0];    [UINavigationBar appearance].tintColor = [UIColor whiteColor];    NSDictionary *NavTextAttribute = @{                                       //字型顏色                                       NSForegroundColorAttributeName:[UIColor whiteColor],                                       //字型大小                                       NSFontAttributeName:[UIFont boldSystemFontOfSize:18]};    [UINavigationBar appearance].titleTextAttributes = NavTextAttribute;

2.更改UINavgation的navigationItem返回ButtonItem文字

UIBarButtonItem *backItem = [[UIBarButtonItem alloc] init];backItem.title = @"返回";self.navigationItem.backBarButtonItem = backItem;
