Can't get the path of the file - iphone

Question

The code was working 100% but after shifting to iOS7 and XCode 5 I can't get the path of the file using NSFilemanager methods, the code can't find the path to timetableXML file and triggers -> else #"NO such a file exist", Here is there code:
- (void)viewDidLoad
{
[super viewDidLoad];
APUAppDelegate *appDelegate = (APUAppDelegate *)[[UIApplication sharedApplication]delegate];
context = [appDelegate managedObjectContext];
dispatch_queue_t queue = dispatch_get_global_queue(0,0);
dispatch_async(queue, ^{
NSLog(#"Beginning download");
NSString *stringURL = #"http://webspace.apiit.edu.my/intake-timetable/download_timetable/timetableXML.zip";
NSURL *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
NSLog(#"Got the data!");
//Find a cache directory. You could consider using documenets dir instead (depends on the data you are fetching)
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *path = [paths objectAtIndex:0];
//Save the data
NSLog(#"Saving");
dataPath = [path stringByAppendingPathComponent:#"timetableXML.zip"];
dataPath = [dataPath stringByStandardizingPath];
[urlData writeToFile:dataPath atomically:YES];
/////////////////// TEST
// Existence of the xml file
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *pathToMyFile = [path stringByAppendingPathComponent:#"timetableXML.zip"];
if ([fileManager fileExistsAtPath:pathToMyFile]) {
// file exists
NSLog(#"YES a file exist with ZIP extension");
NSLog(#"Unziped successfully!");
path1 = pathToMyFile;
[self unzipFile:path1];
}
else {
NSLog(#"NO such a file exist");
}
});
}

When writing the file the path is created with this code:
dataPath = [path stringByAppendingPathComponent:#"timetableXML.zip"];
dataPath = [dataPath stringByStandardizingPath];
but when testing the path is created with this code which is not the same:
NSString *pathToMyFile = [path stringByAppendingPathComponent:#"timetableXML.zip"];
NSLog() both paths and try to find the problem.
Look and see if the file was written.
Note, there there was no check of the status of the writeToFile: method, add that error check.
