Colour Picker Test

Still don't know much about UIAlertView and other system default dialog boxes. Was testing this Colour Picker code from

As screen dump above, quite nice but still don't fully understand some of the codes yet unfortunately...

For example, inside "presetSlidersWithColor" and "presetSlidersWithRandomColor", how come only calls
[self performSelector:@selector(redSliderValueChanged:) withObject:redSlider afterDelay:0.0];

Then, what about "greenSlider" and "blueSlider", don't they also have to be called?

Also this part about "setFrame" too...

- (void)setFrame:(CGRect)rect

Still got a lot more stuffs to learn...Now where was I? Got lost again... back to the schedule...
