自定义UIImagePickerController的后退按钮？

Question

如何在UIImagePickerController中将“相册”后退导航按钮自定义为“照片”？

我试试运气

任何想法如何自定义相册背面导航按钮。

UIImagePickerController *albumPicker = [[UIImagePickerController alloc]init];
[albumPicker setDelegate:self];

[albumPicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
popOverController = [[UIPopoverController alloc]initWithContentViewController:albumPicker];

[popOverController presentPopoverFromRect:CGRectMake(0,0,templatePhotoPlaceholderView.frame.size.height/2,templatePhotoPlaceholderView.frame.size.height) inView:templatePhotoPlaceholderView permittedArrowDirections:UIPopoverArrowDirectionAny animated:NO];
[popOverController setPopoverContentSize:CGSizeMake(320, 480)];
[albumPicker release];

我想自定义相册，照片已显示在图像中，已保存的照片显示为照片 怎么做我尝试它不适合我

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
    UINavigationItem *ipcNavBarTopItem;

    // add done button to right side of nav bar
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Photos"
                                                                   style:UIBarButtonItemStylePlain 
                                                                  target:self 
                                                                  action:@selector(saveImages:)];

    UINavigationBar *bar = navigationController.navigationBar;
    [bar setHidden:NO];
    ipcNavBarTopItem = bar.topItem;
    ipcNavBarTopItem.title = @"Photos";
    ipcNavBarTopItem.rightBarButtonItem = doneButton;
}

这解决了问题的问题。

您应该能够将此代码应用于您的控制器：

UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithTitle:@"Photo" style:UIBarButtonItemStyleBordered target:self action:@selector(buttonPressed:)];
self.navigationItem.leftBarButtonItem = btn; // or rightBarButtonItem
[btn release];

self是一个UIViewController - 还记得你需要为选择器设置action方法。

或者，您可以通过向下钻取控制器的按钮视图然后设置其标题来访问左/右按钮。

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