Question

I’m new to iphone development. I added 3 types of categories to a UIImagePickerController (For example, “Wild animals”, “African animals” and “Water animals”)

If the user taps on “wild animals”, for example, how can I display just that category of images?

Answer 1

Set the delegate for pickerView.

The following delegate method will be called for each item selection

- (void)pickerView:(UIPickerView  *)pickerView didSelectRow:(NSInteger)row  inComponent:(NSInteger)component

The row value gives the selected item

Place a imageView in the view and change the image according to selected value.

self.imageView.image=[UIImage imageNamed:@"wildanimals.jpg"];
