Question

Two views need to be resized when a button is clicked in iPad .
I Tried it with following code

[UIView animateWithDuration:1.0 animations:^{
    //Target Rect of the View will be given here                         
}];

It works fine with iPad4.2 ,but Crashes with 3.2 version(Incompatible).
On Googling found that 3.2 version supports only Animating Views (W/O Blocks)
Source:
http://developer.apple.com/library/iOS/#documentation/UIKit/Reference/UIView_Class/UIView/UIView.html#//apple_ref/occ/clm/UIView/beginAnimations:context:

They have mentioned its not advisable to use it for 4.0 and later
How can I achieve animating the views for both 3.2 and 4.2.

I you really need to support versions below 4.0, you can use this:

[UIView beginAnimations:@"animation" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:1.0]; //In seconds
//Here do your stuff
int newPosY = myImage.frame.origin.y - 10;
[myImage setFrame:CGRectMake(self.frame.origin.x, newPosY, myImage.frame.size.width,     myImage.frame.size.height)];

[UIView commitAnimations];

That moves an UIImageView 10 pixels up.

Also check UIView reference to see all the possibilities.
