how i can call this function in app delegate ?this function is declared and define in view controller named productDetail.m .And i want to execute this function for my entire app. help will be appreciated.

Answer 1

Write the function in Appdelegate.m
And call from viewController.m
form this code:
AppDelegate *appDelegate;
appDelegate= (AppDelegate *)[UIApplication sharedApplication].delegate;
[appDelegate findAllSupplement];
Or you can declare the funtion globally. like:
In ViewController.h
+ (void) findAllSupplement;
And Define the funtion in ViewControler.m
+ (void) findAllSupplement
{
// your code here
}
And you can call the funtion from any class.
