ios - UIImagePickerController 不显示所选图像

Question

我有一个 UIImagePickerController，我在 Ipad 中使用它，但是当您选择其中一张图像时没有任何反应，这里是选择器的代码:

- (IBAction)addPicture:(id)sender {
    CGRect rect = CGRectMake(0, 0, 753, 118);
    [popOverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [self dismissViewControllerAnimated:YES completion:nil];
    patientPicture = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    UIImageView *pictureView = (UIImageView *)[imageCell viewWithTag:777];
    pictureView.image = patientPicture;
    [_imgViewAdd reloadInputViews];
}
-(void)viewDidLoad {
    pickerController = [[UIImagePickerController alloc] init];
    popOverController = [[UIPopoverController alloc] initWithContentViewController:pickerController];
    popOverController.delegate = self;
}

发生的事情是图像选择器加载正常，但当我去挑选其中一张图片时什么也没有发生

提前致谢

Answer 1

调用:

[self dismissViewControllerAnimated:YES completion:nil];

最后而不是第一个。

还有...

@interface yourViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate>

您没有设置 pickerController 委托(delegate)...

pickerController.delegate = self;

因为你有一个弹出窗口使用这个..

[popOverController dismissPopoverAnimated:YES];
