Question

Here in image view, how to add next and previous buttons (front and back options) programmatically in iPhone?

Answer 1

Adding Button in image View?

If so, code as follows

    UIButton *nextBut=[UIButton buttonWithType:UIButtonTypeRoundedRect];
    nextBut.frame= CGRectMake(x, y, 120, 100);
    [nextBut setTitle:@"Next" forState:UIControlStateNormal];
    [nextBut addTarget:self action:@selector(nextbuttonAction) forControlEvents:UIControlEventTouchUpInside];
    [self.imageView addSubview:nextBut];
    [nextBut release];

    UIButton *prevBut=[UIButton buttonWithType:UIButtonTypeRoundedRect];
    prevBut.frame= CGRectMake(x, y, 120, 100);
    [prevBut setTitle:@"Previous" forState:UIControlStateNormal];
    [prevBut addTarget:self action:@selector(prevbuttonAction) forControlEvents:UIControlEventTouchUpInside];
    [self.imageView addSubview:prevBut];
    [prevBut release];

x,y is the position of the button in your view.

Then code for the button actions,

-(IBAction)nextbuttonAction
{
//Next Button Action
}

-(IBAction)prevbuttonAction
{
//Previous Button Action
}

EDIT:

set the pickerView delegate. In the following method code as follows,

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
 imageView.image=[UIImage imageNamed:[imageArray objectAtIndex:row]];
}
