Question

I’m having some trouble catering for the new iPhone 5 screen height, I need to resize my table view already to show an advert.

Up till iOS6 I didn’t have a problem, I used the following function, but it doesn’t use scale. To be honest I’m surprised it works.

+ (CGRect)setTableBoundsByHeight:(int)lHeight:(UITableView*)tbl {
    CGRect tableFrame = tbl.frame;
    return CGRectMake(tableFrame.origin.x,
                      tableFrame.origin.y,
                      tableFrame.size.width,
                      lHeight);
}

Here’s the code, where I have hard coded the height of my table view at 367, that’s minus the height of a navigation controller and a tab bar. 50 is the height of the advert.

if (!productPurchased) {
#ifdef VER_FREE  
    [[LARSAdController sharedManager] 
           addAdContainerToView:self.view withParentViewController:self];
    [[LARSAdController sharedManager] 
           setGoogleAdPublisherId:@"number"];
    [reportTableView setFrame:[General 
           setTableBoundsByHeight:(367-50):reportTableView]];
#endif
} else {
    [reportTableView setFrame:[General 
           setTableBoundsByHeight:367:reportTableView]];
}

I’ve found some code which scales but I’m not sure how to implement this.

CGFloat scale = [UIScreen mainScreen].scale;
result = CGSizeMake(result.width * scale, result.height * scale);

If this code is inside your view controller, just use self.view.bounds.height rather than 367.

By the way: You should really rename

+ (CGRect)setTableBoundsByHeight:(int)lHeight:(UITableView*)tbl

to something like

+ (CGRect)setTableBoundsByHeight:(int)lHeight tableView:(UITableView *)tbl
