Not able to print my json data in my console? - ios

Question

here is my code. I used NSDictionary and coded to print my json data in my console.but i got error like this:
'NSInvalidArgumentException', reason: '-[__NSCFString objectForKeyedSubscript:]: unrecognized selector sent to instance 0x7c971930'
My code:
if(buttonIndex == 0) {
NSLog(#"OK Button is clicked");
}
else if(buttonIndex == 1) {
if([[textView.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length]!=0)
{
if(!self.note)
{
NSManagedObjectContext *context = [self managedObjectContext];
NSManagedObject *newNote = [NSEntityDescription insertNewObjectForEntityForName:#"Notes" inManagedObjectContext:context];
NSLog(#"%#",textView.text);
[newNote setValue:textView.text forKey:#"note"];
if([textView.text length]>30)
{
[newNote setValue:[NSString stringWithFormat:#"%#...",[textView.text substringToIndex:25]] forKey:#"title"];
}
else
[newNote setValue:textView.text forKey:#"title"];
[newNote setValue:[NSDate date] forKey:#"mod_time"];
//[newDevice setValue:self.versionTextField.text forKey:#"version"];
//[newDevice setValue:self.companyTextField.text forKey:#"company"];

Answer 1

I guess you can get data like below this
NSDictionary *monday = jsonResults[#"original"];
NSArray * arrFile = monday[#"files"];
for (NSDictionary *theCourse in arrFile)
{
....
}

Answer 2

Did you checked that received data (i.e., returnData) from sendSynchronousRequest: is returning a plain data?
If the data received is in Base64, you might have to decode this NSData to plain data, and then go ahead with String conversion.
NSData *decodedData = [[NSData alloc] initWithBase64EncodedData:responseData options:NSDataBase64DecodingIgnoreUnknownCharacters];
NSString *str = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];

// convert Json to NSDictionary
NSDictionary *jsonResults = [NSJSONSerialization JSONObjectWithData:returnData options:NSJSONReadingMutableContainers error:nil];
// NSLog(#"%#",jsonResults);
int count = [[jsonResults valueForKey:#"count"] intValue];
NSArray *arrayData = [jsonResults copy];
NSMutableArray *arrayPDFName = [[NSMutableArray alloc]init];
for(int i = 0;i < [arrayData count];i++)
{
NSDictionary *dictOriginal = [[arrayData objectAtIndex:2]valueForKey:#"original"];
int countOriginal = [[dictOriginal valueForKey:#"count"] intValue];
NSLog(#"The countOriginal is - %d",countOriginal);
NSArray *arrayFiles = [[dictOriginal valueForKey:#"files"] copy];
NSLog(#"The arrayFiles are - %#",arrayFiles);
for(int j=0;j<[arrayFiles count];j++)
{
NSString *strCreatedTime = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:j] valueForKey:#"created_time"]];
NSString *strLastModifiedTime = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:j] valueForKey:#"last_modified_time"]];
NSString *strID = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:j] valueForKey:#"id"]];
NSString *strName = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:j] valueForKey:#"name"]];
NSLog(#"The created_time is - %#",strCreatedTime);
NSLog(#"The last_modified_time is - %#",strLastModifiedTime);
NSLog(#"The is is - %#",strID);
NSLog(#"The name is - %#",strName);
[arrayPDFName addObject:strName];
}
}
