Keep Adding to NSMutable Array

I am pretty new to Objective-C, and trying to create a to-do list app with a table view. I am trying to keep adding strings to my mutable array as the button is pressed. But each time I press the button only the last string gets added to the array. 

- (IBAction)notebutton:(UIButton *)sender {

   NSMutableArray *mystr = [[NSMutableArray alloc] init];
   NSString *name = _noteField.text;
   [mystr addObject:name];
   [self.tableView reloadData];
}

You Are creating mutable array on method. so each time its Allocating and making new array.

Just allocate the nsmutable array in viewdidload/viewdidappear and add object in your method.

Do not declare the NSMutableArray each time. Declare it only once.

Make NSMutableArray *mystr; as a property and allocate it in viewDidLoad() once.

in .h or .m file

@property(nonatomic,strong) NSMutableArray *mystr;

viewDidLoad()

self.mystr = [[NSMutableArray alloc] init];

- (IBAction)notebutton:(UIButton *)sender {

   NSString *name = _noteField.text;
   [self.mystr addObject:name];
   [self.tableView reloadData];
}
