ios - 无法在控制台中打印我的json数据？

Question

这是我的代码。我使用NSDictionary进行编码以在控制台中打印我的json数据。但是出现了这样的错误:

   'NSInvalidArgumentException', reason: '-[__NSCFString objectForKeyedSubscript:]: unrecognized selector sent to instance 0x7c971930'

我的代码:

  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"];

如何克服此问题以正常工作并在控制台中打印数据
帮帮我。我奋斗了2个小时。我用谷歌搜索并更改了所有更改。但是无法在控制台中获取数据。提前致谢

我想你可以得到像这样的数据

NSDictionary *monday = jsonResults[@"original"];
NSArray * arrFile = monday[@"files"];
for (NSDictionary *theCourse in arrFile)
{
    ....
}
