Yes but that is OK when you write your code into the process :
Code:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
....
}
But if you write your code for example into
Code:
- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
...
}
This is a méthod of a pickerViewController.
That isn't OK , your label don't change the color background
Then what you purpose ?
