定制后退按钮出现在的UIImagePickerController(Customized back

我用下面的代码来定义整个我的应用程序导航栏上的后退按钮：

UIImage *backButton = [[UIImage imageNamed:@"backButton"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
UIImage *backButtonOn = [[UIImage imageNamed:@"backButton_on"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButton
                                                  forState:UIControlStateNormal
                                                barMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonOn
                                                  forState:UIControlStateHighlighted
                                                barMetrics:UIBarMetricsDefault];

它除了当我出示的UIImagePickerController，然后在照片库中的后退按钮也是定制后退按钮专辑的伟大的工作。 我怎样才能找回在图像拾取原来的后退按钮？

Answer 1:

尝试使用这样的：

    [[UINavigationBar appearanceWhenContainedIn:[YourClassThatsNotAUIImagePicker class], nil] setBackButtonBackgroundImage:someOtherImage forBarMetrics:UIBarMetricsDefault];

这应该限制你的外观设置，只需要列出类，因此先不谈的UIImagePickerController。

Answer 2:

 [[UIBarButtonItem appearanceWhenContainedIn:[UIImagePickerController class], nil] setBackButtonBackgroundImage:[UIImage imageNamed:@"blank-button"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

这是正确的方式

Answer 3:

1.适用于快速和ios9（上面的回答会像） -

    UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UIImagePickerController.self]).setBackButtonBackgroundImage(UIImage(named: "blank-button"), forState: UIControlState.Normal, barMetrics: UIBarMetrics.Default)

2.如果要修改UINavigationBar的的backIndicatorImage

UINavigationBar.appearanceWhenContainedInInstancesOfClasses([UIImagePickerController.self]).backIndicatorImage = UIImage(named: "backButton")//or nil

3.如果要修改backIndicatorTransitionMaskImage

UINavigationBar.appearanceWhenContainedInInstancesOfClasses([UIImagePickerController.self]).backIndicatorTransitionMaskImage =UIImage(named: "backButton")// nil
