Answer 1

Just put 5 UIButton's with correct frame and correct UIImage for the button state.

Answer 2

The best way to do it is by manipulating UIButtons.

Follow those steps:

• add UIButtons in IB
• connect proper actions to the following methods in your UIViewController class

.

-(IBAction)setTabOne{
    [self resetButtons];
    [tabBTOne setBackgroundImage:[UIImage imageNamed:@"tabOne_on.png"] forState:UIControlStateNormal];
    [tabBTOne setSelected:YES];
    [tabBTOne setUserInteractionEnabled:NO];
}

-(IBAction)setTabTwo{
    [self resetButtons];
    [tabBTTwo setBackgroundImage:[UIImage imageNamed:@"tabTwo_on.png"] forState:UIControlStateNormal];
    [tabBTTwo setSelected:YES];
    [tabBTTwo setUserInteractionEnabled:NO];
}
...

-(void)resetButtons{
    [tabBTOne setSelected:NO];
    [tabBTTwo setSelected:NO];

    [tabBTOne setBackgroundImage:[UIImage imageNamed:@"tabOne.png"] forState:UIControlStateNormal];
    [tabBTTwo setBackgroundImage:[UIImage imageNamed:@"tabTwo.png"] forState:UIControlStateNormal];

    [tabBTOne setUserInteractionEnabled:YES];
    [tabBTTwo setUserInteractionEnabled:YES];
}
