如何更新TableView静态单元格中的数据？

I want to update the values of counts, but I am not able to do that..! I tried it, but it is update when I build a code...!

我想更新计数值，但我无法做到这一点......！我尝试过，但是当我构建代码时它会更新......！

Here is a screenshot of a tableview:

以下是tableview的屏幕截图：

Here is the code for this,

这是代码，

2 个解决方案

#1

do one thing, in viewDidLoad method add method like

做一件事，在viewDidLoad方法中添加方法就好

[self update];

then, add that code in this method.

然后，在此方法中添加该代码。

-(void)update{


    userDefaults=[NSUserDefaults standardUserDefaults];
    globalVariables=[GlobalVariables sharedInstance];
    NSLog(@"Role : %@",[userDefaults objectForKey:@"role"]);
    _user_role.text=[[userDefaults objectForKey:@"role"] uppercaseString];

    _user_nameLabel.text=[userDefaults objectForKey:@"profile_name"];
    _url_label.text=[userDefaults objectForKey:@"baseURL"];

    [_user_profileImage sd_setImageWithURL:[NSURL URLWithString:[userDefaults objectForKey:@"profile_pic"]]
                          placeholderImage:[UIImage imageNamed:@"default_pic.png"]];
    _user_profileImage.layer.borderColor=[[UIColor hx_colorWithHexRGBAString:@"#0288D1"] CGColor];

    _user_profileImage.layer.cornerRadius = _user_profileImage.frame.size.height /2;
    _user_profileImage.layer.masksToBounds = YES;
    _user_profileImage.layer.borderWidth = 0;


    _view1.alpha=0.5;
    _view1.layer.cornerRadius = 20;
    _view1.backgroundColor = [UIColor purpleColor];

    _view2.alpha=0.5;
    _view2.layer.cornerRadius = 20;
    _view2.backgroundColor = [UIColor purpleColor];


    _view3.alpha=0.5;
    _view3.layer.cornerRadius = 20;
    _view3.backgroundColor = [UIColor purpleColor];


    _view4.alpha=0.5;
    _view4.layer.cornerRadius = 20;
    _view4.backgroundColor = [UIColor purpleColor];

    _view5.alpha=0.5;
    _view5.layer.cornerRadius = 20;
    _view5.backgroundColor = [UIColor purpleColor];


    NSInteger open =  [globalVariables.OpenCount integerValue];
    NSInteger closed = [globalVariables.ClosedCount integerValue];
    NSInteger trash = [globalVariables.DeletedCount integerValue];
    NSInteger unasigned = [globalVariables.UnassignedCount integerValue];
    NSInteger my_tickets = [globalVariables.MyticketsCount integerValue];

    if(open>99){
        _c1.text=@"99+";
    }else
        _c1.text=@(open).stringValue;
    if(closed>99){
        _c4.text=@"99+";
    }else
        _c4.text=@(closed).stringValue;
    if(trash>99){
        _c5.text=@"99+";
    }else
        _c5.text=@(trash).stringValue;
    if(unasigned>99){
        _c3.text=@"99+";
    }else
        _c3.text=@(unasigned).stringValue;
    if(my_tickets>99){
        _c2.text=@"99+";
    }else
        _c2.text=@(my_tickets).stringValue;

    [self.tableView reloadData];

}

and add this code,

并添加此代码，

-(void)viewWillAppear:(BOOL)animated{

 [self.tableView reloadData];
    //[self.tableView reloadData];

}

and call getDependencies method in viewDidLoad method. check it once and let me know..!

并在viewDidLoad方法中调用getDependencies方法。检查一次，让我知道..！

You can create IBOutlet for all labels which needs to be updated. Instead of reloading tableview on updating count you can update the count any where in your controller class. You can move all the code related to updating count in separate method and call this method whenever its required.

您可以为需要更新的所有标签创建IBOutlet。您可以在控制器类的任何位置更新计数，而不是在更新计数时重新加载tableview。您可以在单独的方法中移动与更新计数相关的所有代码，并在需要时调用此方法。

 func updateAllLabels() {
    NSInteger open =  [globalVariables.OpenCount integerValue];
    NSInteger closed = [globalVariables.ClosedCount integerValue];
    NSInteger trash = [globalVariables.DeletedCount integerValue];
    NSInteger unasigned = [globalVariables.UnassignedCount integerValue];
    NSInteger my_tickets = [globalVariables.MyticketsCount integerValue];

    if(open>999){
        _inbox_countLabel.text=@"999+";
    }else
        _inbox_countLabel.text=@(open).stringValue;
    if(closed>999){
        _closed_countLabel.text=@"999+";
    }else
        _closed_countLabel.text=@(closed).stringValue;
    if(trash>999){
        _trash_countLabel.text=@"999+";
    }else
        _trash_countLabel.text=@(trash).stringValue;
    if(unasigned>999){
        _unassigned_countLabel.text=@"999+";
    }else
        _unassigned_countLabel.text=@(unasigned).stringValue;
    if(my_tickets>999){
        _myTickets_countLabel.text=@"999+";
    }else
        _myTickets_countLabel.text=@(my_tickets).stringValue;
}

And call this updateAllLabels method when values get update. If you are aware that only one value will get update you can update that label only.

并在值更新时调用此updateAllLabels方法。如果您知道只有一个值会更新，则只能更新该标签。
