用户关闭视图后重新加载tableviewcontroller

Question

I have a UITableviewController and a button where upon click another UIViewController will appear

    [self presentViewController:newPopupViewController animated:YES completion:nil];

Then, when i click the close button in this UIViewController ( newPopupViewController ) will be removed and the UITableVIewController that was there before will be displayed.

[self dismissViewControllerAnimated:YES completion:Nil];

When the UITableVIewController appears i want to reload the table Data. How can i do this.

Answer 1

-(void)viewWillAppear:(BOOL)animated {
   // Relead data here
}

Answer 2

You can use a block. Suppose you have FirstViewController and NewPopupViewController, so in the NewPopupViewController.h file write,

@property (nonatomic, copy) void(^ReturnBlock)(BOOL);

and in the NewPopupViewController.m file where you dismiss the ViewController set,

self.ReturnBlock(YES);
[self dismissViewControllerAnimated:YES completion:nil];

So in the FirstViewController where you call the presentViewController write,

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
NewPopupViewController *newPopupViewController = [storyboard instantiateViewControllerWithIdentifier:@"FirstView"]; // The Identifier should be from the Storyboard
[self presentViewController:newPopupViewController animated:YES completion:nil];
[newPopupViewController setReturnBlock:^(BOOL flag)
{
    if (!flag)
    {
       //reload you table here 
    }
}];
