iOS应用程序仅在特殊情况下与NSURLConnection发生冲突

我的iOS应用程序仅在部署时崩溃（ad hoc） - 我已在本地测试应用程序，并且似乎从未出现过相同的问题。它与发送HTTP Post请求有关。iOS应用程序仅在特殊情况下与NSURLConnection发生冲突

这是崩溃日志：

Exception Type: EXC_BAD_ACCESS (SIGSEGV) 
Exception Subtype: KERN_INVALID_ADDRESS at 0x00000000c18bbec8 
Triggered by Thread: 0

这是代码：

NSMutableURLRequest * request = [NSMutableURLRequest new]; 
    [request setURL:addURL]; 
    [request setHTTPMethod:@"POST"]; 

    // setup the request headers 
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
    [request setHTTPBody:holder]; 

NSURLResponse * response = nil; 
    NSData * receivedData = nil; 

    receivedData = [NSMutableData data]; 

    // this next line throws an error 
    receivedData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

的尝试调试的部署版本为什么应用程序崩溃的任何想法（或任何提示？应用程序）

以下是完整的崩溃报告：

请提供完整的符号化崩溃报告。请注意：绝对不要在主线程中使用'sendSynchronousRequest'！永远不能。 – Kerni 2014-09-27 00:13:04

你推荐使用什么？ – scientiffic 2014-09-27 00:17:40

改为使用sendAsynchronousRequest。尝试在发布配置中构建并查看是否发生 – KDaker 2014-09-27 00:23:01
