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的时候都是标准格式，json数据当中没有 /n /r /t 等制表符。

今天在解析的时候发现json解析时好时坏，用在线json解析也米有问题。找了半天终于发现是制表符在作怪，由于标准的json解析是不允许有这几个制表符的。所以在收到保温的时候我们需要把这几个制表符给过滤掉。

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;

//系统自带的解析方式。

NSDictionary * userInfo = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:&e];if (e) {NSLog(@"%@",e);}
