window.google.ac.h(["Y",[["young thug",0],["youtube",0],["youth troye sivan",0],["young dolph",0],["yo gotti",0],["yg",0],["yoga",0],["you should be here cole swindell",0],["yandere simulator",0],["young thug best friend",0]],{"k":1,"l":"1","q":"Fu65vJmwPDpRvrCvJ_hO3MqI15U"}])

   @property(strong, nonatomic) NSMutableArray *ParsingArray // Put that in .h file or after @interface in your .m file

  -(void)autocompleteSegesstions : (NSString *)searchWish{
//searchWish is the text from your search bar (self.searchBar.text)


NSString *jsonString = [NSString stringWithFormat:@"http://suggestqueries.google.com/complete/search?client=youtube&ds=yt&alt=json&q=%@", searchWish];
    NSString *URLString = [jsonString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; // Encoding to identify where, for example, there are spaces in your query.


NSLog(@"%@", URLString);

    NSData *allVideosData = [[NSData alloc]initWithContentsOfURL:[[NSURL alloc]initWithString:URLString]];

NSString *str = [[NSString alloc]initWithData:allVideosData encoding:NSUTF8StringEncoding];
NSLog(@"%@", str); //Now you have NSString contain JSON. 
NSString *json = nil;
NSScanner *scanner = [NSScanner scannerWithString:str];
[scanner scanUpToString:@"[[" intoString:NULL]; // Scan to where the JSON begins
[scanner scanUpToString:@"]]" intoString:&json];
//The idea is to identify where the "real" JSON begins and ends.
json = [NSString stringWithFormat:@"%@%@", json, @"]]"];
NSLog(@"json = %@", json);


NSArray *jsonObject = [NSJSONSerialization JSONObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding] //Push all the JSON autocomplete detail in to jsonObject array.
                                                                                 options:0 error:NULL];
self.ParsingArray = [[NSMutableArray alloc]init]; //array that contains the objects.
for (int i=0; i != [jsonObject count]; i++) {
    for (int j=0; j != 1; j++) {
        NSLog(@"%@", [[jsonObject objectAtIndex:i] objectAtIndex:j]);
        [self.ParsingArray addObject:[[jsonObject objectAtIndex:i] objectAtIndex:j]];
        //Parse the JSON here...

    }

Resolve this for There are two things to know here:

In iOS 9, by default, http:// is not supported. You must communicate securely (with https://). You can turn off this feature in your Info.plist if you have to. NSFileManager URLs must be paths to files on disk — that is, they must be file URLs. Yours is not; it's an http:// URL. If your goal is to download a file and then copy it somewhere, use NSURLSession's download task.
