UIImagePickerController没有将图像分配给uiimageview

Question

I am trying to use the UIImagePickerController and save the image to a UIImageView but it the image isn't saved?

- (IBAction)handleAvatarTap:(id)sender {
DLog(@"");

UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

[picker dismissModalViewControllerAnimated:YES];
UIImage* original =[info objectForKey:@"UIImagePickerControllerOriginalImage"];

// This is the line that sets the image but the original image assigned to it is still there?
[self.avatarImage setImage:[UIImage imageWithCGImage:original.CGImage]];


}

Answer 1

Are you sure that avatarImage is init?

Something like:

self.avatarImage = [[[UIImageView alloc] initWithFrame:myFrame] autorelease];
self.avatarImage.image = original;

Answer 2

将用户互动设置为已启用，现在可以使用。
