關於iOS7.0以後修改navigationBar的返回按鈕的文本、顏色、自定義按鈕等等
1、返回按鈕的顏色
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
2、設置返回按鈕的內容
A -> B
在push的時候，在A中添加代碼：
UIBarButtonItem *backItem = [[UIBarButtonItem alloc] init];
backItem.title = @"你的文字";
self.navigationItem.backBarButtonItem = backItem;
3、自定義navigationBar按鈕
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"全部已讀" style:UIBarButtonItemStylePlain target:self action:@selector(allReadedTapped)];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"backIcon"] style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonTouched:)];
4、自定義navigationBar的title內容和字體大小、顏色
self.title = @"登 錄";
self.navigationController.navigationBar.titleTextAttributes = @{
NSFontAttributeName:[UIFont systemFontOfSize:17],
NSForegroundColorAttributeName:[UIColor whiteColor]
};
5、設置navigationBar的背景顏色
self.navigationController.navigationBar.barTintColor = [UIColor colorFromHexRGB:@"3bad6f" alpha:1.0f];
