NSMutableArray *temp = [NSMutableArray array];
NSMutableArray *titles = [NSMutableArray array];

for (NSInteger i=0; i<12; i++) {
    UIView *view = [[UIView alloc]init];
    view.backgroundColor = [UIColor colorWithRed:arc4random_uniform(256)/255.0f green:arc4random_uniform(256)/255.0f blue:arc4random_uniform(256)/255.0f alpha:1];
    [temp addObject:view];
