Xcode 7 [Objective-c]方法冲突？

Question

我运行我的应用程序时会添加分数，但在点击它后不会更改阻止位置。

- (IBAction)Block:(id)sender{

Random = arc4random() %219;
Random = Random + 61;

BlockI.center = CGPointMake(0, Random);
BlockB.center = CGPointMake(0, Random);

[self Score];

}

- (void)Score{

ScoreInt = ScoreInt + 1;
Score.text = [NSString stringWithFormat:@"%li", (long)ScoreInt];
[[NSUserDefaults standardUserDefaults] setInteger:ScoreInt forKey:@"ScoreSaved"];

}

现在，如果我删除部分：

[self Score];

和

 - (void)Score{

ScoreInt = ScoreInt + 1;
Score.text = [NSString stringWithFormat:@"%li", (long)ScoreInt];
[[NSUserDefaults standardUserDefaults] setInteger:ScoreInt forKey:@"ScoreSaved"];
}

然后我得到了该块的随机放置，但是当我点击它时，得分不会增加。

Answer 1

您还没有synchronize NSUserDefaults所以synchronize NSUserDefaults

[[NSUserDefaults standardUserDefaults] synchronize];

Answer 2

要将值存储在NSUserDefaults中，因此必须同步NSUserDefaults。如果不同步NSUserDefaults，则不会设置您的设置值。编写代码......

- (void)Score
{
   ScoreInt = ScoreInt + 1;
   Score.text = [NSString stringWithFormat:@"%li", (long)ScoreInt];
   [[NSUserDefaults standardUserDefaults] setInteger:ScoreInt forKey:@"ScoreSaved"];
   [[NSUserDefaults standardUserDefaults] synchronize];
}
