Answer 1

use [tableView reloadData] for updating tableview

Answer 2

Simple Use this Do not need to view refresh or reload
-(void)viewWillAppear:(BOOL)animated
{
[tableView reloadData]
[super viewWillAppear:animated];
}

Answer 3

Your data source array profilearray keeps getting re-assigned the same value every time the view appears. Maybe initialise it once in viewDidLoad.
After the array is updated, use [tableView reloadData] to reload the table view.
Do not call viewDidLoad on your own, and get rid of setNeedsDisplay for now.

Answer 4

Just use this.
- (void)viewDidLoad
{
[super viewDidLoad];
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
profilearray=[[NSMutableArray alloc]initWithObjects:#"First Name:",#"Last Name:",#"Date of Birth:",#"Email:",#"Gender:",#"Address:",#"Country:",#"State:",#"City:",#"ZipCode:",#"Phone:",#"Guardian / Caretaker Details:",#"Name:",#"Relationship:",#"Email:",#"Doctor Details:",#"Name:",#"Phone:",#"Email:",#"Insurance Details:",#"Name:",#"Email:",nil];
[tableView reloadData];
}
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}

Answer 5

profilearray:- Perhaps this is your array from where you are getting data in tableview and also storing data in it
viewWillAppear :- this method is called when view is appear
[tableView_Outlet reloadData] :- this method reload your tableview with new data
So in this scenario never call viewWillAper Because this is not standard way to do
Find point where your data is updated then call "reloadData"
