更改UIImagePickerController的NavigationBar标题

Question

我想知道如何更改UIImagePickerController的导航栏标题。我尝试了几种方法，但无法做到。

尝试了以下方式，

imgPicker.title = [NSString stringWithString:@"My Name"];
imgPicker.navigationItem.title = [NSString stringWithString:@"My Name"];

但它仍然给我一个名为“相册”的默认标题。任何人都可以告诉我该怎么做？....

...谢谢

Answer 1

我找到了办法。当您将UIImagePickerController委托设置为self并实现以下方法时，它可以工作。

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

这应该允许你设置标题（上一个答案有错字）：

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [viewController.navigationItem setTitle:@"Choose A Photo"];
}
