Переменная недоступна, импорт предоставляется в Xcode

Question

У меня возникли проблемы с доступом к переменной «megaBubbleUpgradeTier» из моего класса FirstViewController.m. Я пытаюсь получить доступ к нему здесь:

FirstViewController.m

#import "FirstViewController.h" 
#import "customTableCell.h" 
//#import "RWGameData.h" 

@interface FirstViewController() 

@end 

@implementation FirstViewController 
{ 
    NSArray *upgrades; 
    NSArray *thumbnails; 
    NSArray *descriptions; 
    NSArray *megaBubbleUpgradeFees; 
    NSInteger rowID; 
} 

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Upgrades" ofType:@"plist"]; 
    NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path]; 

    upgrades = [dict objectForKey:@"UpgradeStrings"]; 
    thumbnails = [dict objectForKey:@"UpgradeImages"]; 
    descriptions = [dict objectForKey:@"UpgradeDescriptions"]; 
    megaBubbleUpgradeFees = [dict objectForKey:@"MegaBubbleUpgradeFee"]; 

    _regularBubbleLabel.text = [NSString stringWithFormat:@"%li", [RWGameData sharedGameData].regularBubbleCount]; 
    _premiumBubbleLabel.text = [NSString stringWithFormat:@"%li", [RWGameData sharedGameData].premiumBubbleCount]; 

} 

- (void)didReceiveMemoryWarning { 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return [upgrades count]; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    // Handles appearance of cells in table. 

    static NSString *TableIdentifier = @"TableCell"; 

    customTableCell *cell = (customTableCell *)[tableView dequeueReusableCellWithIdentifier:TableIdentifier]; 

    if (cell == nil) { 
     //cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TableIdentifier]; 
     NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"customTableCell" owner:self options:nil]; 
     cell = [nib objectAtIndex:0]; 
    } 

    cell.primaryImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]]; 
    cell.upgradeNameLabel.text = [upgrades objectAtIndex:indexPath.row]; 
    cell.descriptionLabel.text = [descriptions objectAtIndex:indexPath.row]; 
    cell.regularCurrencyIcon.image = [UIImage imageNamed:@"megaBubbleLarge30.png"]; 

    cell.regularBubbleCostLabel.text = [NSString stringWithFormat:@"%@", megaBubbleUpgradeFees[[RWGameData sharedGameData].megaBubbleUpgradeTier]]; 


    return cell; 
}

    return 78;

    if (rowID == 0) { 
     messageAlert = [[UIAlertView alloc] initWithTitle:@"Not enough bubbles!!" message:@"You need to collect more bubbles or purchase them from our store!" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:@"Buy", nil]; 
     [messageAlert show]; 
     NSLog(@"Cell ID: 0"); 
    } else if (rowID == 1) { 
     messageAlert = [[UIAlertView alloc] initWithTitle:@"Not enough bubbles!!" message:@"You need to collect more bubbles or purchase them from our store!" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:@"Buy", nil];

     NSLog(@"Cell ID: 4"); 
    }

Проблема заключается в том, что [RWGameData sharedGameData] .megaBubbleUpgradeTier не кажется, чтобы быть доступным из класса. Любые идеи почему? При необходимости я могу предоставить дополнительную информацию. # RWGameData.h, который объявляет переменную, уже импортирован в заголовочный файл FirstViewController, поэтому он должен быть доступен в соответствующем файле .m, FirstViewController.m.

Answer 1

ли вы помните, чтобы добавить строку

#import "RWGameData.h" 

В верхней части исходного файла? Если вы не импортируете заголовок, компилятор не знает об этом классе и подумает, что в этом классе не найдено ВСЕ.

EDIT:

Попробуйте изменить эту строку:

+(instancetype)sharedGameData; 

Чтобы прочитать

+(RWGameData *)sharedGameData; 

Я держал пари, что фиксирует ее.

Answer 2

Я создал новый проект и передал его вручную. Я могу только предположить, что что-то не так на конце Xcode, что было предложено ранее JoshCaswell, хотя я изо всех сил старался очистить проект, но я, должно быть, что-то пропустил.
