ios - iOS App在重新启动应用程序之前不保存TableView结果？

Question

当我在我的应用程序中选择特定的颜色主题时，它只会更新在myCustomTableView该页面上选择的颜色（从），当我转到下一页时，颜色与我选择的颜色不同，它没有更新.

如果我完全关闭应用程序（从运行中删除）然后重新加载应用程序，它将以我选择的颜色出现。似乎默认值并未实时存储在应用程序中，仅在重新启动时才存储。

文件的.m开头也使用；

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        
        
           NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
            NSString *documentsDirectory = [paths objectAtIndex:0]; 
            cameraFilePath = [documentsDirectory stringByAppendingPathComponent:@"camera_Data.plist"];          
           NSFileManager *fileManager = [NSFileManager defaultManager];
        if(![fileManager fileExistsAtPath:cameraFilePath])
        {
             NSString *bundlePath=[[NSBundle mainBundle] pathForResource:@"camera_Data" ofType:@"plist"];
            [fileManager copyItemAtPath:bundlePath toPath:cameraFilePath error:nil];
            
        }
        
        // Custom initialization.
    }
    return self;
}

正在调用该表viewDidLoad
