Where to set popover size? - objective-c

Question

I have a UIViewController called HomeViewController and it has a model that contains an array of data. HomeViewController also has a button that when pressed will show a UITableViewController that display's the model's array of data.
My question is, what is the standard/best way to set the popover's size? I only want the popover to be tall enough to display the data, but no taller. What is common practice? I assume that I need to set contentSizeForViewInPopover at some point but I'm not sure where...In the viewDidLoad method of the popover class? In the prepareForSegue method?
Here's the code I have so far: (Note that DataPresentingViewController is my popover view controller class`)
//In HomeViewController
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.destinationViewController isKindOfClass:[DataPresentingViewController class]])
{
DataPresentingViewController *dest = (DataPresentingViewController *) segue.destinationViewController;
dest.mySavedData = self.myModel.mySavedData;
}
}
I know that I could just set the contentSizeForViewInPopover here in the prepareForSegue method; however, this seems like something the popover class should deal with.

Answer 1

As of iOS7 contentSizeForViewInPopover is deprecated. You should use UIViewController's preferredContentSize property instead.
Hope this helps!

Answer 2

set contentSizeForViewInPopover in ViewDidLoad method in HomeViewController

Answer 3

contentSizeForViewInPopover is deprecated in iOS 7
The property: popoverContentSize of UIPopoverController represents the size of the content view that is managed by the view controller in the contentViewController property of UIPopoverController.
Reference
The advantage is that it is available in iOS 3.2 and later, so you don't need to check device version everytime, just replace contentSizeForViewInPopover method with your UIPopOverController object instance.

Answer 4

Have you tried:
setPopoverContentSize:<#(CGSize)#> animated:<#(BOOL)#>
in your segue logic block. Useful if you want the popover size to be variable based upon a data set, or view placement or whatever.

Answer 5

// self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0); //Deprecated in ios7
self.preferredContentSize = CGSizeMake(320.0, 600.0); //used instead

Answer 6

A little known trick to sizing your UIPopoverViewController to match the height of your UITableView is to use the tableView's rectForSection method to give you the height. Use the height in your viewController's contentSizeForViewInPopover like this:
- (CGSize)contentSizeForViewInPopover {
// Currently no way to obtain the width dynamically before viewWillAppear.
CGFloat width = 200.0;
CGRect rect = [self.tableView rectForSection:[self.tableView numberOfSections] - 1];
CGFloat height = CGRectGetMaxY(rect);
return (CGSize){width, height};
}

Answer 7

Try the following code:
- (IBAction)setData:(id)sender
{
UIViewController *popoverContent=[[UIViewController alloc] init];
UITableView *tableView=[[UITableView alloc] initWithFrame:CGRectMake(265, 680, 0, 0) style:UITableViewStylePlain];
UIView *popoverView=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 300)];
popoverView.backgroundColor=[UIColor whiteColor];
popoverContent.view=popoverView;
popoverContent.contentSizeForViewInPopover=CGSizeMake(200, 420);//setting the size
popoverContent.view=tableView;
tableView.delegate=self;
tableView.dataSource=self;
self.popoverController=[[UIPopoverController alloc] initWithContentViewController:popoverContent];
[self.popoverController presentPopoverFromRect:CGRectMake(400, 675, 0, 0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
}

Answer 8

It looks like you want to do it programmatically, but in the storyboard, before you hook up a view controller to a segue, under the attributes inspector there is a "popover, use explicit size option." Maybe you can set the size that would work the best for your App first and not worry about the size with using code. Hope this helps, let us know how it goes.
