ios - Changing alpha value with increment of x coordinate value -



ios - Changing alpha value with increment of x coordinate value -

is possible give different alpha values same view @ same time? want display color in uiview, should faded out direction. means want alter alpha value within increasing x coordinate value.

yes can accomplish this, have remember range alpha value 0-1. in case can define can define alter according width ie

float changeinalphaperx = 1/self.frame.width;

and getting changed x value, can do..

view.alpha = changeinalphaperx * x;

hope helps..
