ios 系统自带相册修改返回键颜色

    viewController.navigationController.navigationBar.tintColor = [UIColor blackColor];

- (void)navigationController:(UINavigationController*)navigationController willShowViewController :(UIViewController*)viewController animated:(BOOL)animated

{

    viewController.navigationController.navigationBar.tintColor = [UIColor blackColor];

}

仅做笔记 ~
