如何在UIImagePickerController中给出Title？

Question

我想在UIImagePickerController中给出标题，如图片截图所示

Answer 1

将UIImagePickerController委托设置为self并实施UINavigationControllerDelegate的以下方法：

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [viewController.navigationItem setTitle:@"<Your-Title>"];
}

Answer 2

您尝试此代码：

- (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;
}

您需要在Swift中实现QAbstractListModel的委托方法：
