segue.destinationviewcontroller is not what expecting why?

I tried creating a segue in my project, the segue is working perfectly, but when I tried setting the value of some property it gives me an error.

unrecognised selector sent to instance 0x13fe42550

After some debugging I found that

segue.destinationViewController

is a UIViewController instead of my own controller class (MyClass)

I tried the following:

if ([segue.destinationViewController isKindOfClass:[MyClass class]]) {
    MyClass *mainViewConroller = segue.destinationViewController;
    NSInteger tagIndex = [(UILabel *)sender tag];
    mainViewConroller.id = @"65";
}

However, it's not returning an instance of the expected class name set in the class section of IB.

Solution

  • The usual way to distinguish multiple segues is the identifier 

    if ([segue.identifier isEqualToString:@"reviewDetail"]) {
    MyClass *mainViewController = (MyClass *)segue.destinationViewController;
    NSInteger tagIndex = [(UILabel *)sender tag];
    mainViewController.id = @"65";
}
