Initialize ViewController in iOS 7

Question

I used to initialize my UIViewController in - (void) viewDidLoad.

Since the update to iOS 7 the viewDidLoad method is either not called or after executing setItemAndParents.

Example:

I have a UITableViewController if you click on a cell the desired view is loaded:

- (void)tableView: (UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath {
    // some more code
    [cpvc setItemAndParents:items[selectedIndex] orderIndex:indexOrder];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    cpvc = segue.destinationViewController;
}

Where am I supposed to initialize the ViewController.

Remember with iOS 6 everything worked find.

Can you verify that "`cpvc`" is nil when you click on a table cell? — Michael Dautermann, Sep 22 '13 at 20:52
@MichaelDautermann it's not nil - else I would get a nil/null pointer exception - isn't it?? Don't understand your question anyway — Thorsten Niehues, Sep 27 '13 at 11:43

Had similar problem.

I inserted this right after allocation of viewController (or in some case after pushViewController):

viewController.view.hidden = NO;

and it calls viewDidLoad.

Hope I helped.

This is working because as soon as you ask for 'view' property, the controller loads it and viewDidLoad is called – ipodishima Dec 10 '13 at 20:14

Yup it happens to me also... You can initialized view controller in - (void)awakeFromNib{} method. This method help me in the same scenario as you have.

Great - now I initialize my variables in -(void)awakeFromNib and the GUI elements in viewDidLoad :) – Thorsten Niehues Sep 27 '13 at 11:45
