Question

I have an ipad app, that as user does some actions, uitextfields and buttons, appear and disapear from the view [working fine]

[cancelBtn setHidden: true];
[lblOption setHidden:true];

the question is if there is some way to animate when they appear and disappear, like a transition, transparent alpha to the button for example,

thanks a lot!

Answer 1

Yes. For instance:

[UIView animateWithDuration:1 animations:^{
    cancelBtn.alpha = 0;
}];

See the View Programming Guide for iOS for details.
