3、主要用法及功能

QBImagePicker用于获取iOS本地图像，并支持获取多个图片或视频。

QBImagePickerController *imagePickerController = [QBImagePickerController new];
imagePickerController.delegate = self;
imagePickerController.allowsMultipleSelection = YES;
[self presentViewController:imagePickerController animated:YES completion:nil];

1.获取到图像

- (void)qb_imagePickerController:(QBImagePickerController *)imagePickerController didFinishPickingAssets:(NSArray *)assets {
    for (PHAsset *asset in assets) {
        // Do something with the asset
    }
    [self dismissViewControllerAnimated:YES completion:nil];
}

2.取消获取图像

- (void)qb_imagePickerControllerDidCancel:(QBImagePickerController *)imagePickerController {
//do something
 [self dismissViewControllerAnimated:YES completion:nil];
}

3.更改选择图像时获取到通知

- (void)qb_imagePickerController:(QBImagePickerController *)imagePickerController didDeselectAsset:(PHAsset *)asset{
    NSLog(@"取消选中");
}
- (void)qb_imagePickerController:(QBImagePickerController *)imagePickerController didSelectAsset:(PHAsset *)asset{
    NSLog(@"选中");
}
- (BOOL)qb_imagePickerController:(QBImagePickerController *)imagePickerController shouldSelectAsset:(PHAsset *)asset{
    return YES;
}

4.设置选择图像数量

imagePickerController.allowsMultipleSelection = YES;//允许多选（默认是NO，不允许多选）
imagePickerController.minimumNumberOfSelection = 3;//设置选择图像数量下限
imagePickerController.maximumNumberOfSelection = 6;//设置选择图像数量上限

5.指定要显示的相册

imagePickerController.assetCollectionSubtypes = @[
    @(PHAssetCollectionSubtypeSmartAlbumUserLibrary), //相机胶卷
    @(PHAssetCollectionSubtypeAlbumMyPhotoStream), //我的照片流 
    @(PHAssetCollectionSubtypeSmartAlbumPanoramas), //全景图
    @(PHAssetCollectionSubtypeSmartAlbumVideos), //视频
    @(PHAssetCollectionSubtypeSmartAlbumBursts) //连拍模式拍摄的照片
];

6.设置媒体类型

imagePickerController.mediaType = QBImagePickerMediaTypeAny;//图片和视频
imagePickerController.mediaType = QBImagePickerMediaTypeImage;//图片
imagePickerController.mediaType = QBImagePickerMediaTypeVideo;//视频

7.设置每行显示的图像数量

imagePickerController.numberOfColumnsInPortrait = 4;//竖屏模式下一行显示4张图像
imagePickerController.numberOfColumnsInLandscape = 7;//横屏模式下一行显示7张图像

8.显示提示信息

imagePickerController.prompt = @"请选择图像!";//在界面上方显示文字“请选择图像!”
imagePickerController.showsNumberOfSelectedAssets = NO;//在界面下方显示已经选择图像的数量
