如何访问相册中保存的照片？

我在应用程序中使用代码将照片保存到自定义的相册中

[library saveImage:self.capturedImg toAlbum:@"FunCam" withCompletionBlock:^(NSError *error) { if (error!=nil) { NSLog(@"Big error: %@", [error description]); } }]; 

现在我想检索保存到该相册的所有照片，当用户点击一些button，并显示他们像相机应用程序（iPhone上的默认应用程序）的视图显示

请帮我，我该怎么做？

提前致谢

试试这些方法…

 -(void)loadNewLibraryImages { self.assetGroups = [[NSMutableArray alloc] init]; // Group enumerator Block dispatch_async(dispatch_get_main_queue(), ^ { void (^assetGroupEnumerator)(struct ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop) { if (group == nil) { return; } if ([[group valueForProperty:ALAssetsGroupPropertyName] isEqualToString:@"YOUR ALBUM NAME"]) { [self.assetGroups addObject:group]; [self loadImages]; return; } if (stop) { return; } }; // Group Enumerator Failure Block void (^assetGroupEnumberatorFailure)(NSError *) = ^(NSError *error) { UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"ERROR" message:[NSString stringWithFormat:@"No Albums Available"] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; [alert release]; }; // Enumerate Albums ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; [library enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:assetGroupEnumerator failureBlock:assetGroupEnumberatorFailure]; }); } -(void)loadImages { //for (ALAssetsGroup *assetGroup in self.assetGroups) { // for (int i = 0; i<[self.assetGroups count]; i++) { ALAssetsGroup *assetGroup = [self.assetGroups objectAtIndex:0]; NSLog(@"ALBUM NAME:;%@",[assetGroup valueForProperty:ALAssetsGroupPropertyName]); [assetGroup enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop) { if(result == nil) { return; } UIImage *img = [UIImage imageWithCGImage:[[result defaultRepresentation] fullScreenImage] scale:1.0 orientation:(UIImageOrientation)[[result valueForProperty:@"ALAssetPropertyOrientation"] intValue]]; }]; // } } 

希望他们会帮助….
