ios - UIImagePickerController 未将图像分配给 uiimageview

Question

我正在尝试使用 UIImagePickerController 并将图像保存到 UIImageView 但图像没有保存？

- (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

你确定 avatarImage 是 init 吗？

就像是：

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

将用户交互设置为启用，它现在可以工作了。
