}

you should creating own subclass of uiviewcontroller or uitableviewcontroller (whichever you're using) , place code in viewdidload method of subclass. controllers need code can extend custom class. save hassle of having write code everywhere.

your custom subclass:

@interface customviewcontroller : uiviewcontroller  @end 

your viewdidload method in subclass:

@implementation customviewcontroller     - (void)viewdidload {         [super viewdidload];          // custom code here...     } @end 

extend custom class controllers want have common stuff done in:

@interface visuallychangedviewcontroller : customviewcontroller  @end  @implementation visuallychangedviewcontroller     - (void)viewdidload {         [super viewdidload];     } @end
