标题: ios - UIImagePickerController 不显示所选图像

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，这里什么都没有发生，这是选择器的代码:

- (IBAction)addPictureid)sender {
    CGRect rect = CGRectMake(0, 0, 753, 118);
    [popOverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
-(void)imagePickerControllerUIImagePickerController *)picker didFinishPickingMediaWithInfoNSDictionary *)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;
}

发生的情况是图像选择器加载正常，但当我去选择其中一张图片时，什么都没有发生

提前致谢

Best Answer-推荐答案

调用:

[self dismissViewControllerAnimated:YES completion:nil];

最后而不是第一个。

还有……

@interface yourViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate>

你没有设置pickerController委托(delegate)...

pickerController.delegate = self;

因为你有一个弹出框使用这个..

[popOverController dismissPopoverAnimated:YES];
