自定义 UzysAssetsPickerController 的外观

如果您想自定义 UzysAssetsPickerController 的外观，您可以初始化 UzysAppearanceConfig 实例，并配置其属性，然后在初始化 UzysAssetsPickerController 之前调用

    + (void)setUpAppearanceConfig:(UzysAppearanceConfig *)config

的 UzysAssetsPickerController

示例代码如下

    UzysAppearanceConfig *appearanceConfig = [[UzysAppearanceConfig alloc] init];
    appearanceConfig.finishSelectionButtonColor = [UIColor blueColor];
    appearanceConfig.assetsGroupSelectedImageName = @"checker";
    [UzysAssetsPickerController setUpAppearanceConfig:appearanceConfig];

有关更多可配置的属性，请参阅 UzysAppearanceConfig.h

打开 UzysAssetsPickerController

    UzysAssetsPickerController *picker = [[UzysAssetsPickerController alloc] init];
    picker.delegate = self;
    picker.maximumNumberOfSelectionMedia = 2;
    [self presentViewController:picker animated:YES completion:^{

    }];

UzysAssetPickerControllerDelegate

- (void)uzysAssetsPickerController:(UzysAssetsPickerController *)picker didFinishPickingAssets:(NSArray *)assets
{
    __weak typeof(self) weakSelf = self;
    if([[assets[0] valueForProperty:@"ALAssetPropertyType"] isEqualToString:@"ALAssetTypePhoto"]) //Photo
    {
            [assets enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
                ALAsset *representation = obj;

                    UIImage *img = [UIImage imageWithCGImage:representation.defaultRepresentation.fullResolutionImage
                                                       scale:representation.defaultRepresentation.scale
                                                 orientation:(UIImageOrientation)representation.defaultRepresentation.orientation];
                weakSelf.imageView.image = img;
                *stop = YES;
            }];


    }
    else //Video
    {
        ALAsset *alAsset = assets[0];

        UIImage *img = [UIImage imageWithCGImage:alAsset.defaultRepresentation.fullResolutionImage
                                           scale:alAsset.defaultRepresentation.scale
                                     orientation:(UIImageOrientation)alAsset.defaultRepresentation.orientation];
        weakSelf.imageView.image = img;



        ALAssetRepresentation *representation = alAsset.defaultRepresentation;
        NSURL *movieURL = representation.url;
        NSURL *uploadURL = [NSURL fileURLWithPath:[[NSTemporaryDirectory() stringByAppendingPathComponent:@"test"] stringByAppendingString:@".mp4"]];
        AVAsset *asset      = [AVURLAsset URLAssetWithURL:movieURL options:nil];
        AVAssetExportSession *session =
        [AVAssetExportSession exportSessionWithAsset:asset presetName:AVAssetExportPresetMediumQuality];

        session.outputFileType  = AVFileTypeQuickTimeMovie;
        session.outputURL       = uploadURL;

        [session exportAsynchronouslyWithCompletionHandler:^{

            if (session.status == AVAssetExportSessionStatusCompleted)
            {
                NSLog(@"output Video URL %@",uploadURL);
            }

        }];

    }
