Question

我正在iPhone上的.aspx上加载一个UIWebView网络表单，表单已成功加载。现在表单中有一个选择照片按钮，用户可以从iPhone图库和一个提交按钮中选择照片/图像。选择照片后，当我点击表单上的提交按钮时，它会抛出“request body stream exhausted”之类的错误。我也在谷歌搜索但没有运气。这是代码段

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.

[activity startAnimating];
activity.hidden = NO;

NSURL *url = [NSURL URLWithString:@"http://rest..com:95134/MobileForm.aspx?processName=NewForm"];

theRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60];
[theRequest setHTTPMethod:@"POST"];
[theRequest setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];//image/jpeg
[theRequest setValue:@"image/jpeg" forHTTPHeaderField:@"Content-Type"];// "Content-Type" = "text/html; charset=utf-8";

[webView loadRequest:theRequest];

}

但我可以上传图片并从设备上的Safari应用程序提交表单。请帮我。提前谢谢。
