ios - 关闭 UIImagePickerController

Question

我已经尝试了各种关闭 UIImagePickerController 的方法，但都没有成功。我做错了什么。

- (IBAction)choosePhoto
{
    self.picker = [[UIImagePickerController alloc] init];
    self.picker.delegate = self;
    self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:self.picker animated:YES];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)imagePicker
{
    NSLog(@"dismiss image picker");
    [self dismissModalViewControllerAnimated:NO];
    [[self.picker parentViewController] dismissModalViewControllerAnimated:NO];
    [self.presentedViewController dismissModalViewControllerAnimated:NO];
    [self.presentingViewController dismissModalViewControllerAnimated:NO];
     // And every other way i could think of
}

- (void)imagePickerController:(UIImagePickerController *)imagePicker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    .. same stuff here
}

我已经尝试从父级、祖父级、navigationController 和根 Controller 中呈现选择器，但没有任何效果。无论我做什么，我都无法关闭 ImagePickerController。

请注意每次都会调用日志语句。

干杯

Answer 1

试试这条线。它可能对您有用。

[self.picker dismissModalViewControllerAnimated:NO];

对于 iOS 6 及更高版本使用此

[self.picker dismissViewControllerAnimated:NO completion:nil];

也可以使用此代码来呈现您的选择器 Controller

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
    [self presentViewController:self.picker animated:YES completion:nil];
} else {
    //To target iOS 5.0
    [self presentModalViewController:self.picker animated:YES];
}
