[cell.contentView addSubview:cell.btn1];

[[cell btn2] addTarget:self action:@selector(btnMinus:event:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:cell.btn2];

[cell.contentView addSubview:cell.txt1];

the handler Methods code is

-(void)btnPlus:(id)sender event:(id)event
{
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:myCollection];
NSIndexPath *indexPath = [myCollection indexPathForItemAtPoint: currentTouchPosition];
NSLog(@"%@", indexPath);

 }

thats all i have done ,,, now please help me to resolve or figure out my problem.

just want to take input in textfield in specific cell and then get this text to save….

Answer 1

You should create an XIB for UICollectionviewCell. That will be an easier approach. Take IBOutlets for buttons and textfield. You have already set them as properties. In your method you have got the indexpath. So you are very near to the solution. You can get the UICollectionViewCell using the method UICollectionViewCell *cell = [collectionView cellForItemAtIndexPath:indexPath];

Then you can access properties of these cells.

Answer 2

When you click the button you will store the indexpath value to global string. when you hit the button you reload collectionView then you display global indexpath string values to TextField.
