为什么我的整数不在视图控制器之间传输？ [英] Why isn't my integer transferring between view controllers?

问题描述

我将在游戏中为额外的生命设置IAP，但在我这样做之前，我想测试它是否会从我的购买View Controller转移到我的游戏View Controller而不是。在我的购买VC中我有

I am going to be setting up IAP for extra lives in my game, but before I do that I wanted to test to see if it would transfer from my purchasing View Controller to my game View Controller and it's not. In my purchasing VC I have

-(void)StartView{
//Life = [[NSUserDefaults standardUserDefaults] integerForKey:@"Life"]; (If in the code then it will not update the LifeCounter.text)
livesUpdated = [NSTimer scheduledTimerWithTimeInterval:0.0001 target:self selector:@selector(LiveUpdatedCheck) userInfo:nil repeats:YES];
}


-(void)LiveUpdatedCheck{
LifeCounter.text = [NSString stringWithFormat:@"%li", (long)Life];
}


-(void)LiveUpdatedCheck{
LifeCounter.text = [NSString stringWithFormat:@"%li", (long)Life];
}


-(IBAction)TenLifePurchase:(id)sender{
    Life = Life + 10;
}

然后在我的游戏VC中我有

Then in my game VC I have

-(IBAction)StartGame:(id)sender{
Life = [[NSUserDefaults standardUserDefaults] integerForKey:@"Life"];
LifeCounter.text = [NSString stringWithFormat:@"%li", (long)Life];
}

'Life'在我的两个.h文件中被声明为NSInteger，我使用了userDefaults就像这样在两个视图控制器之间移动我的高分，并通过id整数改变球的颜色。我该如何解决这个问题？可能是因为在我的购买控制器和我的游戏控制器之间，你必须通过一个没有生命信息的主屏幕？此外，当您在查看游戏控制器后返回购买的控制器时，它会从任何数字重置为0，但如果您查看任何其他控制器然后返回购买，则该数字将存储而不会重置为0.

'Life' is declared as an NSInteger in both of my .h files and I used userDefaults just like this to move my high score between 2 view controllers and the same for changing the color of a ball via id integers. How can I fix this problem? Could it be because in-between my purchase controller and my game controller you have to go through a main screen that has no information on 'Life'? Also when you go back to the purchased controller after viewing the game controller it resets back to 0 from whatever number it was, but if you view any other controller then back to purchased then the number will store and not reset back to 0.
