Ios 如何在服务器上发布多个图像？
我试图将多个映像发布到服务器，但只有一个映像将发送到服务器。我正在尝试保存多个图像。我的代码在下面，请告诉我哪里错了。我见过这个发布多张图片的例子 谢谢Ios 如何在服务器上发布多个图像？,ios,objective-c,image-uploading,Ios,Objective C,Image Uploading,我试图将多个映像发布到服务器，但只有一个映像将发送到服务器。我正在尝试保存多个图像。我的代码在下面，请告诉我哪里错了。我见过这个发布多张图片的例子 谢谢 NSData *imageData1 = UIImageJPEGRepresentation(photo1, 0.8); NSData *imageData2 = UIImageJPEGRepresentation(photo2, 0.8); NSData *imageData3 = UIImageJPEGRepresenta

返回字符串的打印说明：

您可以使用此代码。它已经过测试，我正在使用这种方法上传多个图像以及其他参数
