ios - 在 UIView 中使用 UIImagePickerController

Question

我有一个按钮，当我点击它时会显示相机(完美运行)

- (IBAction)getPhoto:(id)sender
{
    NSLog( @"Button clicked!" );
    imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
    }

    else {  // IF the device doesn't have a camera, so use the photos album
        [imagePicker setSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum];
    }

    [self addSubview:imagePicker.view];
}

之后我可以拍摄图像等 - 但是当我单击“使用”时:我的方法没有发生任何事情:图像选择器不会关闭它自己:应用程序什么都不做，我正在尝试使用我刚刚拍摄的图像并将其显示在屏幕上的 CGRect 中。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:YES completion:NULL];

    UIImageView *patientImage = [[UIImageView alloc] init];
    patientImage.frame = CGRectMake(625, 25, 83, 103);

    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.patientImage.image = chosenImage;
}

即使我在没有拍照的情况下点击取消按钮，imagePicker(相机界面)也不会自行关闭

如有任何帮助、建议或指导，我们将不胜感激。

You shouldn't be doing the "addSubview" thing up there而是这样做:

[self presentViewController:imagePicker animated:YES completion:nil];
