Question

Anyoone can help me on how to add action to call the following method using UIButton.

-(void)navigatePics:(id)sender andIndex:(NSInteger *)index{}

Answer 1

Use the button.setTag:(NSInteger) method to add the index to the UIButton as a tag.

UIButton *button = ...;
[button setTag:1234];
[button addTarget:self action:@selector(navigatePics:) forControlEvents:UIControlEventTouchUpInside];

Then in navigatePics, read the tag.

-(void)navigatePics:(UIButton *)sender
{
 int index = sender.tag;
 // index = 1234;
}
