I have a source code where the main screen has 10 buttons (images buttons), each button is linked to sql database with tableview items, in the XIB I select which tag for each button, 1, 2, 3, 4..

I want make these buttons to scroll, how to do so?

I tried to convert the view into scrollview, then I have deleted the images, and created buttons in the scrollview, but now I do not know how to link each of the button to its tag in the tableview?

below is what I used:

@implementation mainViewController;

@synthesize master; @synthesize model;

  • (void)viewWillAppear:(BOOL)animated{

    UIScrollView *scrollview=[[UIScrollView alloc]initWithFrame:CGRectMake(0,0,320,480)]; scrollview.showsVerticalScrollIndicator=YES; scrollview.scrollEnabled=YES; scrollview.userInteractionEnabled=YES; [self.view addSubview:scrollview]; scrollview.contentSize = CGSizeMake(320,960);//You Can Edit this with your require scrollview.pagingEnabled=YES;

    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button addTarget:self action:@selector(aMethod:) forControlEvents:UIControlEventTouchDown]; [button setTitle:@"Show View" forState:UIControlStateNormal]; button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);

    UIImageView* imageview1 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"[email protected]"]]; imageview1.frame=CGRectMake(18.0, 18, 285,50); [scrollview addSubview:imageview1];

    UIImageView* imageview2 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"[email protected]"]]; imageview2.frame=CGRectMake(18.0, 78, 285,50); [scrollview addSubview:imageview2];

    UIImageView* imageview3 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"[email protected]"]]; imageview3.frame=CGRectMake(18.0, 138, 285,50); [scrollview addSubview:imageview3];

    UIImageView* imageview4 =[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"[email protected]"]]; imageview4.frame=CGRectMake(18.0, 198, 285,50); [scrollview addSubview:imageview4];

Better approach would be to use UICollectionView if you have option. – Obj-Swift

Assingn a tag to the button when you create it:

[buttonName setTag:1];
[buttonName addTarget:self action:@selector(aMethod:) forControlEvents:UIControlEventTouchDown];

Then use:

-(void)aMethod:(UIButton *)button {
 if ([button tag] == 1) {
  ...do something...
 }
}

Hope this helps.
