请使用下面的代码
typedef void (^ALAssetsLibraryAssetForURLResultBlock)(ALAsset *asset);
typedef void (^ALAssetsLibraryAccessFailureBlock)(NSError *error);
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset){
ALAssetRepresentation *rep = [myasset defaultRepresentation];
CGImageRef iref = [rep fullResolutionImage];
if (iref){
dispatch_async(dispatch_get_main_queue(), ^{
UIImage *myImage = [UIImage imageWithCGImage:iref scale:[rep scale] orientation:(UIImageOrientation)[rep orientation]];
[fileImage addObject:myImage];
//binding ur UI elements in main queue for fast execution
//self.imageView.image = myImage;
});
}
};
ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror){
//failed to get image.
};
ALAssetsLibrary* assetslibrary = [[[ALAssetsLibrary alloc] init] autorelease];
[assetslibrary assetForURL:[filePath objectAtIndex:0] resultBlock:resultblock failureBlock:failureblock];
注:确保,你[文件路径objectAtIndex:0]将是一个NSUrl
对象。请将其转换为NSUrl
,如果不是。
实施例:
ALAssetsLibrary* assetslibrary = [[[ALAssetsLibrary alloc] init] autorelease];
NSURL myAssetUrl = [NSURL URLWithString:[filePath objectAtIndex:0]];
assetslibrary assetForURL:myAssetUrl resultBlock:resultblock failureBlock:failureblock];
可以表明,要存储在阵列中的路径.. – Leena 2012-07-30 13:16:06
资产库://asset/asset.JPG ID = 1000000192&EXT = JPG文件路径(阵列)是存储用户选择的iPhone内置图库的图像路径。 Thx寻求帮助。 – user1562536 2012-07-31 09:54:32
