Question

I have two uiviews 1 child and 1 parent parent view has alpha .30 on click of button I want to change alpha of child view to 1.0 or 0.0 is this possible if yes then how.

Please enlighten me on this.

Thanx in advance

Answer 1

Try with
the alpha property of UIView and This value affects only the current view and does not affect any of its embedded subviews.

Read the Apple Documentation for alpha in UIView.

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIView_Class/UIView/UIView.html

Updated:Try with below

[parentView setBackgroundColor:[[UIColor clearColor] colorWithAlphaComponent:0.5]];
[childView setBackgroundColor:[[UIColor clearColor] colorWithAlphaComponent:1.0]];
