iOS - NSURLConnection finished with error - code -1002

 

網絡請求會異常，好比報錯：Error domain: @"NSURLErrorDomain" - code: 1002

在回調的地方打一個斷點，而後用命令行查看下什麼錯誤： po error
當錯誤是：**[Error Domain=NSURLErrorDomain Code=-1002 ] "unsupported URL" **
*Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSLocalizedDescription=unsupported URL, NSUnderlyingError=0x7fa9b1d06120 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}}  *  的時候是url編碼問題，處理一下URL編碼就行了

我這邊是後臺返回的拼接的接口多了「/」,致使統一的域名格式不統一

處理方法:


iOS 8 要用utf8轉碼：

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];


iOS 8 之後要用這個方法：

urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet characterSetWithCharactersInString:@"#%^{}\"[]|\\<> "].invertedSet];
