Question

我创建一个游戏想要能够添加得分，所以当他们在fb上发布它时会显示出高分，（为了增加一点社交方面）

这是我正在起诉的代码，但它似乎工作并崩溃了应用程序，

- (void)fbDidLogin {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [self postwall];

}
- (void)postwall
{
    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   //kAppId, @"app_id",
                                   @"https://developers.facebook.com/docs/reference/dialogs/", @"link",
                                   @"http://fbrell.com/f8.jpg", @"picture",
                                   @"Watch Ma Balls", @"name",
                                   @"How long can you keep out of the way of ma balls for", @"caption",
                                   @"I reached a score of i% can you beat me!.",highscore, @"description",
                                   nil];

    [facebook dialog:@"feed" andParams:params andDelegate:self];
}

代码可以正常运行

高分

有

有没有办法可以将它添加到字符串中以便显示？

试试这个（假设highscore是int）：

NSString *string = @"I reached a score of ";
string = [string stringByAppendingString:[NSString stringWithFormat:@"%d", highscore]];
string = [string stringByAppendingString:@" can you beat me?"];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   //kAppId, @"app_id",
                                   @"https://developers.facebook.com/docs/reference/dialogs/", @"link",
                                   @"http://fbrell.com/f8.jpg", @"picture",
                                   @"Watch Ma Balls", @"name",
                                   @"How long can you keep out of the way of ma balls for", @"caption",
                                   string, @"description",
                                   nil];
