ios - How do I animate my subviews on adding them? -

i have developed font selection utilizes uipickerview , uitoolbar, both added on touching uibutton.

but kind of pop in looks sloppy.

is there way animate them?

here method adds them (it's called on clicking button) :

-(void)showpicker {     [self.view addsubview:_fontpicker];     [self.view addsubview:pickertb];  } 

you can animate them in couple of ways, easiest fade them in.

fade in

[someview setalpha:0] [self.view addsubview:someview]; [uiview beginanimations:@"fadein" context:nil]; [uiview setanimationduration:0.5]; [uiview setanimationbeginsfromcurrentstate:yes]; [someview setalpha:1]; [uiview commitanimations];  

fade out

float fadeduration = 0.5; [uiview beginanimations:@"fadeout" context:nil]; [uiview setanimationduration:fadeduration ]; [uiview setanimationbeginsfromcurrentstate:yes]; [someview setalpha:0]; [uiview setanimationdidstopselector:@selector(removeview)]; [uiview commitanimations];   -(void) removeview {     [someview removefromsuperview]; } 

something simple that.
