When i load[add] my second view controller to the first. Its allow me tap on other button’s too i need to restrict on taping on any button when its loaded second view controller.

Answer 1

When second view controller added as subview then make all as many buttons u have make userInteractionEnabled to NO which u think not to be taped:

 yourButton.userInteractionEnabled = NO;

When remove second view controller don’t forgot to userInteractionEnabled to YES which were made NO:

 yourButton.userInteractionEnabled = YES;
