AssetsLibrary not producing failure when expected
I have this code:
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library assetForURL:albumCopy
resultBlock:^(ALAsset *asset) {
NSLog(@"success");
...
}
failureBlock:^(NSError *error) {
NSLog(@"fail");
...
}];
[library autorelease];
The problem is that when I give it an image which doesn't exist, the NSLog comes up with:
开发者_如何学PythonCould not find photo 1000000141
success
If this won't show me when a photo doesn't exist, how can I find out?
Solved it!
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library assetForURL:albumCopy
resultBlock:^(ALAsset *asset) {
if (asset == nil) {
//Image not in photo library
}
else {
//Image in photo library
}
}
failureBlock:^(NSError *error) {
//Error
}];
[library autorelease];
