Question

我使用代码从以下问题向wordpress博客发表评论：

Post comment to WordPress Blog from iPhone programmatically

我做了一些修改以从UITextFields获取文本：

- (IBAction)postComment:(id)sender {
    NSString *post_url = @"http://movilarena.com/wp-comments-post.php";
    NSString *post_content = @"comment_post_ID=%@&comment_parent=%@&author=%@&email=%@&comment=%@";

    NSString *post_str = [NSString stringWithFormat:post_content, @"1", @"0", self.txtName.text, self.txtEmail.text, self.txtComment.text];
    NSData *data = [NSData dataWithBytes:[post_str UTF8String] length:[post_str length]];

    NSURL * url = [NSURL URLWithString:post_url];
    NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:url];
    [req setHTTPMethod:@"POST"];
    [req setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
    [req setHTTPBody:data];

    //Synchronous
    NSURLResponse *response;
    NSError *err;
    NSData *ret = [NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&err];

    NSString *retString = [NSString stringWithUTF8String:[ret bytes]];
    NSLog(@"%@",retString);
}

我的问题是sendSynchronousRequest返回错误：

执行被中断，原因：EXC_BAD_ACCESS（代码= 1，地址=为0x0）。该过程已恢复到之前的状态执行。

我会感谢任何建议，以确定这里有什么问题。我使用XCode 4.5.2并在带有iOS 6.0.1的iPhone 4S上运行代码

解决了自己。字段comment_post_ID应该是我要回复的帖子的ID。

NSString *post_content = @"comment_post_ID=%d&comment_parent=%@&author=%@&email=%@&comment=%@";

NSString *post_str = [NSString stringWithFormat:post_content, self.postID, @"0", self.txtName.text, self.txtEmail.text, self.txtComment.text];
