本文为大家分享了iOS图片上传至服务器的具体代码，供大家参考，具体内容如下

在使用app时，从相册中选取图片作为头像是很常用的操作，首先打开相册选择图片，然后将图片保存至本应用的document，最后将document中图片的路径保存至NSUserDefaults和服务器。

从相册中选取图片或拍照

//从相册中选取图片或拍照 - (void)btnActionForEditPortrait:(id) sender { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; picker.allowsEditing = YES; [self presentViewController:picker animated:YES completion:NULL]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { _avatar = info[UIImagePickerControllerOriginalImage]; [self saveImage:_avatar WithName:@"userAvatar"]; //处理完毕，回到个人信息页面 [picker dismissViewControllerAnimated:YES completion:NULL]; [_tableView reloadData]; }

保存图片

//保存图片 - (void)saveImage:(UIImage *)tempImage WithName:(NSString *)imageName { NSData* imageData = UIImagePNGRepresentation(tempImage); NSString* documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString* totalPath = [documentPath stringByAppendingPathComponent:imageName]; //保存到 document [imageData writeToFile:totalPath atomically:NO]; //保存到 NSUserDefaults NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setObject:totalPath forKey:@"avatar"]; //上传服务器 [[HSLoginClass new] uploadAvatar:totalPath]; } //从document取得图片 - (UIImage *)getImage:(NSString *)urlStr { return [UIImage imageWithContentsOfFile:urlStr]; }
