本文介绍了一个iOS应用中实现图片编辑并上传到服务器的过程。通过UIImagePickerController选取图片后进行编辑，并保存为本地文件，再使用ASIFormDataRequest以POST方式上传图片到指定URL。文中详细展示了Objective-C代码实现。
UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"];
NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
documentPath = [documentPath stringByAppendingPathComponent:@"image.png"];
NSData *data = UIImagePNGRepresentation(image);//
[data writeToFile:documentPath atomically:YES];
ASIFormDataRequest *request = [ASIFormDataRequestrequestWithURL:[NSURLURLWithString:@"http://txxxxxxxxxxx"]];
request.requestMethod = @"POST";//设置请求方式
[request addPostValue:[[NSUserDefaultsstandardUserDefaults] objectForKey:@"True_userid"]forKey:@"userid"];
[request addFile:documentPath forKey:@"photo"];
[request setCompletionBlock:^{
NSLog(@"------草泥马%@",request.responseString);
}];
[request setFailedBlock:^{
NSLog(@"asi error: %@",request.error.debugDescription);
}];
[request startAsynchronous];
反反复复，成功上传了，真是草泥马
