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.}
When parsing json, it was all standard format, and there were no tab characters such as \n \r \t in the json data.
Today, when parsing, I found that json parsing is good and bad, and there is also a problem with online json parsing. After searching for a long time, I finally found that it was the tab character that was causing trouble. Since standard json parsing does not allow these tab characters. So when we receive insulation, we need to filter out these tab characters.
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;
//The system comes with analysis method.
NSDictionary * userInfo = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:&e];
if (e) {
NSLog(@"%@",e);
}
