提交多张图片上传视频或图片保存图像：
[objc] view plain copy - (void)viewDidLoad { [super viewDidLoad]; // 保存每次添加的图片 self.imageDataArray = [NSMutableArray array]; } [objc] view plain copy -(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *originalImage = [info valueForKey:UIImagePickerControllerEditedImage] ; // 得到图片的缓存数据 NSData * imagedata = UIImageJPEGRepresentation([originalImage imageByScalingAndCroppingForSize:CGSizeMake(originalImage.size.width, originalImage.size.height)], 0.5); static int index = 1; NSString * newImageName = [NSString stringWithFormat:@"%@%zi%@", Image_Name, index, @".jpg"]; NSString *jpgPath = NSHomeDirectory(); jpgPath = [jpgPath stringByAppendingPathComponent:@"Documents"]; jpgPath = [jpgPath stringByAppendingPathComponent:newImageName]; [imagedata writeToFile:jpgPath atomically:YES]; [self.imageDataArray addObject:imagedata]; index ++ ; // 显示当前上传图片 [self showUploadImage:imagedata]; [picker dismissViewControllerAnimated:YES completion:^{ }]; } 提交单张图片 ：
