游戏中心“完成”按钮不起作用
我正在显示游戏中心排行榜，但它出现后我无法将其关闭 - “完成”按钮不起作用。
这是我的 RootViewController.m 代码：
-(void) showLeaderboard {
GKLeaderboardViewController *leaderboardVC [GKLeaderboardViewController alloc] init] autorelease];
if (leaderboardVC != nil) {
[leaderboardVC setDelegate: self];
[leaderboardVC setCategory: kLeaderboardID];
[leaderboardVC setTimeScope: GKLeaderboardTimeScopeWeek];
[self presentModalViewControllerAnimated: YES];
}
}
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
NSLog(@"Close leaderboard");
[self dismissModalViewControllerAnimated: YES];
}
同样奇怪的是我从未在日志中看到“关闭排行榜”。
I am showing a Game Center Leaderboard but after it appears I can't close it—the "Done" button doesn't work.
Here is my code for RootViewController.m:
-(void) showLeaderboard {
GKLeaderboardViewController *leaderboardVC [GKLeaderboardViewController alloc] init] autorelease];
if (leaderboardVC != nil) {
[leaderboardVC setDelegate: self];
[leaderboardVC setCategory: kLeaderboardID];
[leaderboardVC setTimeScope: GKLeaderboardTimeScopeWeek];
[self presentModalViewControllerAnimated: YES];
}
}
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
NSLog(@"Close leaderboard");
[self dismissModalViewControllerAnimated: YES];
}
What's also strange is that I never see "Close leaderboard" in the log.

您是否将 GKLeaderboardViewControllerDelegate 添加到此类实现的协议列表中？ （leaderboardViewControllerDidFinish 是此协议中的唯一方法）。你的代码看起来很完美，所以这是我唯一能想到的。
Did you add GKLeaderboardViewControllerDelegate to the list of protocols that this class implements? (leaderboardViewControllerDidFinish is the only method in this protocol). Your code looks perfect so this is the only thing I can think of.
