使用UIImagePickerControllerReferenceURL在UIImageView上设置Image

Question

是否可以使用UIImagePickerControllerReferenceURL在UIImageView上设置图像.传统模式使用[info objectForKey:@"UIImagePickerControllerOriginalImage"];

I tried this:

theImageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[info objectForKey:UIImagePickerControllerReferenceURL]]];

但是在UIImageView上没有设置图像.

请帮忙 .

Answer 1

NSURL *referenceURL = [info objectForKey:UIImagePickerControllerReferenceURL];
        ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
        [library assetForURL:referenceURL resultBlock:^(ALAsset *asset)
         {
           UIImage  *copyOfOriginalImage = [UIImage imageWithCGImage:[[asset defaultRepresentation] fullResolutionImage]];
             theImageView.image = copyOfOriginalImage;
         }
                failureBlock:^(NSError *error)
         {
             // error handling
         }];
        [library release];

这段代码就行了.:)
