概要：
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn't be completed. (Cocoa error 3840.)" (Unescaped control character around character 1419.) UserInfo=0x1563cdd0 {NSDebugDescription=Unescaped control character around character 1419.}
之前解析json的時候都是標準格式，json數據當中沒有 /n /r /t 等制表符。
今天在解析的時候發現json解析時好時壞，用在線json解析也米有問題。找了半天終于發現是制表符在作怪，由于標準的json解析是不允許有這幾個制表符的。所以在收到保溫的時候我們需要把這幾個制表符給過濾掉。
NSString * responseString = [request responseString];responseString = [responseString stringByReplacingOccurrencesOfString:@"/r/n" withString:@""];responseString = [responseString stringByReplacingOccurrencesOfString:@"/n" withString:@""];responseString = [responseString stringByReplacingOccurrencesOfString:@"/t" withString:@""];NSLog(@"responseString = %@",responseString);SBJsonParser *parser = [[[SBJsonParser alloc]init] autorelease];id returnObject = [parser objectWithString:responseString];NSDictionary *userInfo = nil;NSArray *userArr = nil;if ([returnObject isKindOfClass:[NSDictionary class]]) {if (userInfo) {[userArr release];}userInfo = (NSDictionary*)returnObject;}else if ([returnObject isKindOfClass:[NSArray class]]) {userArr = (NSArray*)returnObject;}NSError* e = nil;//系統自帶的解析方式。
NSDictionary * userInfo = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:&e];if (e) {NSLog(@"%@",e);}感謝閱讀，希望能幫助到大家，謝謝大家對本站的支持！
