iPhone应用程序通过选择器切换视图

Question

is it possible to switch views using a picker and a button? for instance say i have a picker with various animals and i select frog in the picker and press a button under the picker and it takes me to a view for frogs. i have been trying to figure this out for the last three days and havent been able to figure anything out.

i would be greatly appreciated if you could help me!!!!

 -(void)pickerView:(UIPickerView *)pickerView 
didSelectRow:(NSInteger)row 
  inComponent:(NSInteger)component{
if (row == 1){
    self.view = Cig;
}
}

i have tried something like this but resized its not attached to my button.

Answer 1

Are you forgetting to add the frog view?

// Assume that you have a contentView that is visible
// and then a frogView to add to it when the button is pressed...
[contentView addSubview:frogView];
