inApp采购管理器( cocos2d )

Question

我试图遵循这个教程实现inApp购买在我的游戏中与cocos2d。

但是，当我试图在我的场景中展示产品时，会发现以下错误：

Parse issue, expected expression

在这一行：

[[RageIAPHelper sharedInstance] requestProductsWithCompletionHandler:^BOOL sucess, NSArray *products2] {

这是我在现场的代码：

NSArray *products = nil;
 [[RageIAPHelper sharedInstance] requestProductsWithCompletionHandler:^BOOL sucess, NSArray *products2] {
 if (sucess) {
 products = products2;
 for (int i == 1; i<=products; products.count) {
 SKProduct *product = (SKProduct *) products[i];
 CCLabelTTF *productlabel = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"%@", product.localizedTitle] fontName:@"Verdana-Bold" fontSize:18.0f];
 productlabel.position = ccp(200/i,200);
 }

 }

 }];

这是我的RageIAPHelper.m：

@implementation RageIAPHelper

+ (RageIAPHelper *)sharedInstance {
    static dispatch_once_t once;
    static RageIAPHelper * sharedInstance;
    dispatch_once(&once, ^{
        NSSet * productIdentifiers = [NSSet setWithObjects:
                                      @"com.razeware.inapprage.drummerrage",
                                      @"com.razeware.inapprage.itunesconnectrage",
                                      @"com.razeware.inapprage.nightlyrage",
                                      @"com.razeware.inapprage.studylikeaboss",
                                      @"com.razeware.inapprage.updogsadness",
                                      nil];
        sharedInstance = [[self alloc] initWithProductIdentifiers:productIdentifiers];
    });
    return sharedInstance;
}

@end

NSArray *products = nil;
[[RageIAPHelper sharedInstance] requestProductsWithCompletionHandler:^(BOOL sucess, NSArray *products2) {
 if (sucess) {
   products = products2;
   for (int i == 0; i < products.count; i++) {
     SKProduct *product = (SKProduct *) products[i];
     CCLabelTTF *productlabel = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"%@", product.localizedTitle] fontName:@"Verdana-Bold" fontSize:18.0f];
     productlabel.position = ccp(200/i,200);
   }
 }
}];
