批量上传图片

获取一张图片：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    //获取编辑款中的图片
    //UIImage *pickedImage = [info valueForKey:UIImagePickerControllerEditedImage];
    //获取整张图片
    UIImage *pickedImage = [info valueForKey:UIImagePickerControllerOriginalImage];
    CGSize imgSize = pickedImage.size ;
    if (imgSize.width > imgSize.height)
        imgSize.height = imgSize.width;
    else
        imgSize.width = imgSize.height;

    NSData *data = UIImageJPEGRepresentation(pickedImage, 0.6);

    NSString *fileName = [NSString stringWithFormat:@"%@.jpg",[GlobelConfig getNowTimeTimestamp]];
    [self startUploadFile:data fileName:fileName isMultiple:NO imgAry:@[]];
    [picker dismissViewControllerAnimated:YES completion:NULL];
}

获取多张图片：

TZImagePickerController *imagePickerVc = [[TZImagePickerController alloc] initWithMaxImagesCount:100 delegate:self];
    [imagePickerVc setDidFinishPickingPhotosHandle:^(NSArray<UIImage *> *photo, NSArray * assets, BOOL isSelectOriginalPhoto) {


        NSMutableArray *files = [@[] mutableCopy];
        NSMutableArray *imgAry = [@[] mutableCopy];

        for (NSInteger i = 0; i<photo.count; i++) {
            UIImage *img = photo[i];

            NSString *fileName = [NSString stringWithFormat:@"%@-%ld.jpg",[GlobelConfig getNowTimeTimestamp],i];

            NSData *data = UIImageJPEGRepresentation(img, 0.6);

            NSDictionary *dic = @{@"data":data,@"fileName":fileName};
            [imgAry addObject:img];

            [files addObject:dic];

        }

        NSData *fileData = [NSKeyedArchiver archivedDataWithRootObject:imgAry];
        NSString *fileName = [NSString stringWithFormat:@"%@.jpg",[GlobelConfig getNowTimeTimestamp]];
