Question

I am not dumb and I know how to reload data. I am in a tricky situation where I have a UIView inside another UIView both named OHGridView. I have to keep them named the same way.

With the OHGridView example code, the refresh looked a little like this:

[(OHGridView *)self.view reloadData];

But now that I added a UIView, it no longer works.

Any help is appreciated!

Edit:

Code removed

The NSNotificationCenter may be what you need. You can register for events (eg a perform update event) and then post these events from anywhere. These go to the notification center and then to your class/view. When the event is received, you just do what is needed.

The docs are here:

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSNotificationCenter_Class/Reference/Reference.html

Inside the OHGridView you would call during initialization:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(ReloadNotification:) name:@"ReloadOHGridView" object:nil];

Then, just define the method:

- (void)ReloadNotification:(NSNotification *)notification
{
    [self reloadData];
}

So, when you want an update to occur, you then just call:

[[NSNotificationCenter defaultCenter] postNotificationName:@"ReloadOHGridView" object:self];

When you deallocate the OHGridView you should remove the observer:

[[NSNotificationCenter defaultCenter] removeObserver:self];
