[objc]view plaincopy

NSURL*imageURL = [infovalueForKey:UIImagePickerControllerReferenceURL];

[selfgetImageDetailInfo:imageURL];

//获取图片的详细信息

-(void)getImageDetailInfo:(NSURL*)imageUrl{

__block NSString* imageFileName;

ALAssetsLibrary* assetslibrary = [[ALAssetsLibraryalloc]init];

[assetslibraryassetForURL:imageUrl

resultBlock:^(ALAsset*myasset){

ALAssetRepresentation*representation = [myassetdefaultRepresentation];

imageFileName = [representationfilename];

NSLog(@"图片路径名：%@",imageFileName);

NSLog(@"图片UTI：%@",[representationUTI]);

NSLog(@"图片URL：%@",[representationurl]);
