獲取ASIFormDataRequest響應後的應用程序崩潰

在我的應用程序中，我使用ASIFormDataRequest發送我的新用戶註冊請求。該請求包含用戶詳細信息以及使用base64Encoding轉換的圖像。我也得到了答覆。但應用程序在獲得響應後會崩潰。請幫我解決這個問題。這個代碼有什麼錯誤嗎？獲取ASIFormDataRequest響應後的應用程序崩潰

崩潰日誌？ http://emclstcd.tk – 2012-09-18 06:53:44

崩潰日誌和調用堆棧說什麼？你知道拋出異常的位置嗎？ –

這是一條完全不請自來的建議 - 但您應該認識到ASIHTTPRequest [不再處於開發中]（http://allseeing-i.com/%5Brequest_release%5D），開發人員建議其他開發人員尋找替代方案。如果這是一個新項目，並且您正在尋找異步網絡代碼 - AFNetworking就是其中一種選擇。還有其他人。 – FluffulousChimp

使用委託獲取響應字符串。

[request setDelegate:self]; 
[request setDidFinishSelector:@selector(requestFinished:)]; 
[request setDidFailSelector:@selector(requestFailed:)]; 
[request startAsynchronous];

然後捕獲從委託的響應：

- (void)requestFinished:(ASIHTTPRequest *)theRequest { 
    NSLog(@"response %@",[theRequest responseString]); 
} 

- (void)requestFailed:(ASIHTTPRequest *)theRequest { 
    NSLog(@"response Failed%@, Error:%@",[theRequest responseString],[theRequest error]); 
}

[request setDelegate:self]; 
[request startAsynchronous]; 
NSThread sleepForTimeInterval:5]; 
NSLog(@"response %@",[request responseString]); 
registrationStatusBlock =[[request responseString]JSONValue];

那是什麼？你開始一個異步請求，然後睡覺，然後醒來，就好像你有迴應？這不是異步工作。
