and when user selects on 2nd button, image of button2 should change from first.png to second.png, and also change image of 1st button to default again first.png, so that user came to know he has clicked 2nd button.

in short i want to implement like radio button.

As Ankit explian you this can done in multi ways

I suppose you have created two button add_btn, requestBtn with Interface Builder.

Now you need to set the connection (Event, outlet) for both button.

I think you have knowledge so, I will not explain here how to set button (control) connection (Event, outlet) via inteface builder.

For example: add_btn connected to AddFriends methods and requestBtn with getFriendRequest.

Now you can change the Image of Button As

#pragma mark change Image of first Button
-(void)AddFriends:(UIButton*)sender{       
    [add_btn setImage:[UIImage imageNamed:@"Cliked1.png"] forState:UIControlStateNormal];
    [requestBtn setImage:[UIImage imageNamed:@"unCliked2.png"] forState:UIControlStateNormal]; 
}

#pragma mark change Image of second Button
-(void)getFriendRequest:(UIButton*)sender{
    [add_btn setImage:[UIImage imageNamed:@"unCliked1.png"] forState:UIControlStateNormal];
    [requestBtn setImage:[UIImage imageNamed:@"Cliked2.png"] forState:UIControlStateNormal];
}

I hope it will help you
