如何更新 TableView 静态单元格中的数据？

Question

我想更新计数的值，但我不能这样做..！我试过了，但是当我构建代码时它会更新......！

这是一个表格视图的截图：

这是代码，

#import "LeftMenuViewController.h"
#import "RKDropdownAlert.h"
#import "HexColors.h"
#import "AppConstanst.h"
#import "GlobalVariables.h"
#import "MyWebservices.h"
#import <SDWebImage/UIImageView+WebCache.h>
@import Firebase;
@interface LeftMenuViewController (){
    NSUserDefaults *userDefaults;
    GlobalVariables *globalVariables;
    NSArray *numbers;
}
@end

@implementation LeftMenuViewController

- (id)initWithCoder:(NSCoder *)aDecoder
{
    self.slideOutAnimationEnabled = YES;

    return [super initWithCoder:aDecoder];
}

- (void)viewDidLoad {
    [super viewDidLoad];

    NSLog(@"Naaa-LeftMENU");


    self.tableView.tableFooterView=[[UIView alloc] initWithFrame:CGRectZero];

}

-(void)viewWillAppear:(BOOL)animated{

    userDefaults=[NSUserDefaults standardUserDefaults];
    globalVariables=[GlobalVariables sharedInstance];

    _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;



    NSInteger open =  [globalVariables.OpenCount integerValue];

做一件事，在viewDidLoad方法中添加方法

[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。 检查一次，让我知道..！

您可以为所有需要更新的标签创建IBOutlet。您可以在控制器类中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;
}

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