In the first viewcontroller.m, I put this in the viewDidLoad method:

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handle_data) name:@"reload_data" object:nil];

    -(void)handle_data {
        [yourtableview reloaddata];
    }

In the second viewcontroller.m:

    [[NSNotificationCenter defaultCenter] postNotificationName:@"reload_data" object:self];

Do it in below way:

Suppose you have 2 view controller.

  • ViewController1

  • ViewController2

And you have UITableView object tblTable in ViewController2.

in ViewController2.h file:

@property(nonatomic, retain) UITableView *tblTable;

in ViewController2.m file:

@synthesize tblTable;

Now in in ViewController1.m file:

ViewController1 *objV1 = [ViewController1 alloc]initWithNibName....];

[objV1.tblTable reloadData];

I hope it will be helpful to you.

Let me know in case of any difficulty.

Cheers.

  1. Create property for UITableview with nonatomic and retain.. (view controller 1)

  2. in View Controller 2 create object of viewcontroller 1.

  3. now with help of viewcontroller 1 object you can access it.

Example:

In ViewController2 .m file: 

ViewController1 *objV1 = [ViewController1 alloc]initWithNibName....];   

[objV1.yourTableView reloadData];

I had similar issue and I was using storyboard this is how I fixed it. Suppose u want to reload the table which is in ViewController2 from a function in ViewController1. Do the following:

 #import "ViewController2.h"

Now put this code in the function or any button action under which u want to reload

ViewController2 *ob= (ViewController2*)[self.navigationController topViewController];
    [ob.viewController2Table reloadData];
