Question

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

以下是tableview的屏幕截图：

以下是此代码，

#import "LeftMenuViewController.h"
#import "RKDropdownAlert.h"

@import Firebase;
@interface LeftMenuViewController (){
    NSUserDefaults *userDefaults;
    GlobalVariables *globalVariables;
    NSArray *numbers;
}
@end

@implementation LeftMenuViewController

做一件事，在viewDidLoad方法中添加类似

的方法

[self update];

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];

}

并添加此代码，

-(void)viewWillAppear:(BOOL)animated{

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

}

并在viewDidLoad方法中调用getDependencies方法。检查一下，让我知道..！

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;
}

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。
