How Do I list all the controls inside one UIViewcontroller?

I'm used to .net UI, and I am used to go inside the array of controls inside one container,

I am wondering about ui in cocoa-touch I can do the same, once I didn't find it out there

thanks

You could do it by enumerating the subviews of that container view recursively, checking if they are subclasses of UIControl and adding them to an array. You could create a similar category to UIView(this code is completely untested)

- (NSArray*)containedControls
{
    NSMutableArray *controls = [NSMutableArray array];
    for(UIView *subview in self.subviews){
        if([subview isSubclassOfClass:[UIControl class]])
            [controls appendObject:subview]
        else {
            NSArray *containedInSubview = [subview containedControls];
            [controls addObjectsFromArray:containedInSubview];
        }
    }

    return controls;
}
