Question

I am using a UIButton, on clicking it I want to display the contents that are present in my NSMutableArray in UITableView with the help of UIPopOverController i.e. I want a UITableView to pop up whose cells show the contents of my NSMutableArray.

I am using the following lines of code:

UITableViewController *table= [[UITableViewController alloc]init];

table.delegate = self;

UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:table];
self.popoverController = popover;          
popoverController.delegate = self;


NSString *hDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *hFilePath = [hisDir stringByAppendingPathComponent:@"hhhh.txt"];

NSArray *array = [NSArray arrayWithContentsOfFile:hFilePath ];
NSMutableArray *kkkk = [[NSMutableArray alloc] init];
for (NSDictionary *dict in array) {
    [kkkk addObjectsFromArray:[dict allKeys]];    
}

table = [[UIImageView alloc] initWithFrame:[window bounds]];
// Set up the image view and add it to the view but make it hidden
[window addSubview:table];
table.hidden = YES;
[window makeKeyAndVisible];

I am unable to get the UITableView to pop up on the press of my UIButton. Can anyone help me to sort it out?

Answer 1

One way to show the UITableView in the UIPopOverController is by creating a new UIViewController class. And invoking it in initWithContentViewController method of UIPopOverController.

1. Create a new UIViewController or UITableViewController class. Create an instance of it.

2. Use the instance in the initWithContentViewController method of UIPopOverController.

3. Mention from where it should “pop”

For Example in your Button action :

-(IBAction)yourButtonAction:(id)sender

{
   YourNewViewController*newVC=[[YourNewViewController alloc]init];

   UIPopoverController*somePopOver=[[UIPopoverController alloc]initWithContentViewController:catergoryVC]; //Tell which view controller should be shown
   [somePopOver setPopoverContentSize:CGSizeMake(200, 200)]; // set content size of popover
   [somePopOver presentPopoverFromRect:yourButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; //From where it should "pop"

}

It seems you want to present it from a UIBarButtonItem so instead of presentPopoverFromRect use presentPopoverFromBarButtonItem

 [somePopOver presentPopoverFromBarButtonItem:yourBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
