Dynamic loading of UIScrollview with two columns in iOS- Xcode

Here I made a scroll view with two columns and loading it dynamically with the help of an array: 

In this there are two columns that are loaded with different arrays of images and labels. Providing a great interface.

// This would generate a great scroll view so that all the small and big size images will get handled automatically.

// not even worry about the size of scroll view it would automatically increase as perthe size of images and array. 

This is Scroll View Generation 

  img=[[NSArray alloc]initWithObjects:@"image name",@"image name", nil];

    img1=[[NSArray alloc]initWithObjects:@""image name,@"image name", nil];

  

    lb=[[NSArray alloc]initWithObjects:@"blue",@"green", nil];

    lb1=[[NSArray alloc]initWithObjects:@"black",@"red", nil];

    

    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(5, 112,self.view.frame.size.width ,self.view.frame.size.height)];

    

    

    CGFloat currentY1 = 0.0f;

    CGFloat currentY2 =0.0f;

    

    CGFloat lbCurrentY=0.0f;

    

    CGFloat h1;

    CGFloat h2;

    

    for (int i=0; i<[img count]; i++)

    {

        

        // create image no. 1

    

        NSString *imageName = [img objectAtIndex:i];

        UIImage *image = [UIImage imageNamed:imageName];

        UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

        

        

        // put image on correct position

        CGRect rect = imageView.frame;

        CGFloat width=152;

        CGFloat height=imageView.frame.size.height/3.0;

        rect = CGRectMake(0, currentY1, width, height);

        imageView.frame = rect;

        

        // update currentY

        

        currentY1 += imageView.frame.size.height+5;

        h1=imageView.frame.size.height;

        

        //Puting image on Button 1

        UIButton *btnimage1=[UIButton buttonWithType:UIButtonTypeCustom];

        btnimage1.frame=rect;

        [btnimage1 setImage:imageView.image forState:UIControlStateNormal];

        btnimage1.tag=[[id1 objectAtIndex:i]integerValue];

        NSLog(@"%d",btnimage1.tag);

        

    

     // setting label of the first image

        

        NSString *lbname1=[lb objectAtIndex:i];

        UILabel *label;

        CGFloat lbWidth=width;

        CGFloat lbHeight=30;

        lbCurrentY=h1-30;

         

        label=[[UILabel alloc]initWithFrame:CGRectMake(0, lbCurrentY, lbWidth, lbHeight)];

        label.text=lbname1;

        label.textColor=[UIColor whiteColor];

        label.backgroundColor=[UIColor blackColor];

        label.alpha=0.4;

        [btnimage1 addSubview:label];

        [scrollView addSubview:btnimage1];

        

    }
