ios - 将数据从 plist 添加到 NSSet？

Question

我正在尝试在应用购买中添加产品 ID。但是在下面的代码中，我手动添加了它。如何从 plist 添加它？

我的代码:

@implementation RageIAPHelper

+ (RageIAPHelper *)sharedInstance {
    static dispatch_once_t once;
    static RageIAPHelper * sharedInstance;
    dispatch_once(&once, ^{
        NSSet * productIdentifiers = [NSSet setWithObjects:
                                      @"greatminds.assamkarttestingdays",
                                      @"greatminds.newgirlinthecity",
                                      @"greatminds.newlights",
                                      nil];
        sharedInstance = [[self alloc] initWithProductIdentifiers:productIdentifiers];
    });
    return sharedInstance;
}

将你的 plist 设置为一个数组。然后从 plist 文件加载 NSArray。然后从 NSArray 创建 NSSet。

// Assume you have a plist in the app bundle named "products.plist" with a root of type array
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"products" ofType:@"plist"];
NSArray *products = [NSArray arrayWithContentsOfFile:filePath];
NSSet *productIdentifiers = [NSSet setWithArray:products];
