Actually you cannot. no notice (apple not working well).

But there is a solution:

use viewDidAppear, viewWillAppear, viewWillDesappear, viewDidDesappear family in the viewController that called the presentModalViewController function

Idea:

.h:

 BOOL hasModal; 

.m:

 -(void)presentModal { hasModal = YES; [self presentModalViewController:_viewController animated:YES]; } -(void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if(hasModal) { // your code } } 

Good luck ^^
