在 IBAction 中存储整数并将它们传递给另一个 IBAction

Question

我有一个暂停 IBAction 和一个恢复 IBAction，两者都用于按钮，但我有在游戏过程中收集的游戏点数。我如何在暂停 IBAction 中存储不同的游戏点整数值并将它们传递给恢复 IBAction 方法。

注意：pause IBAction 使所有 NSTIMERS 失效，resume IBAction 重新创建它们。

Answer 1

IBAction 是代码。它不能存储任何东西。您需要将状态保存在某个地方，例如实现 IBAction

的对象的实例变量

Answer 2

为了提供帮助，我找到了一个快速解决方案....但我确信有一个更简洁的方法：

在vc.h中：

NSMutableArray storeVariables;

在vc.m

int a, b, c, d;
- (void)viewDidLoad
{
 [super viewDidLoad];
 a=0;
 b=0;
 c=0;
 d=0;
 storeVariables = [[NSMutableArray alloc] init];
}

-(IBAction)pauseButton:(id)sender{
 a=3;
 b=4;
 c=5;
 d=6;
 [storeVariables addObject:[NSNumber numberWithInt:a]];
 [storeVariables addObject:[NSNumber numberWithInt:b]];
 [storeVariables addObject:[NSNumber numberWithInt:c]];
 [storeVariables addObject:[NSNumber numberWithInt:d]];
 NSLog(@"%d, %d, %d, %d", storeVariables[0], storeVariables[1], storeVariables[2], storeVariables[3]);
}

-(IBAction)resumeButton:(id)sender{
 a = [storeVariables[0]];
 b = [storeVariables[1]]
 c = [storeVariables[2]]
 d = [storeVariables[3]]
 NSLog(@"%d, %d, %d, %d", a, b, c, d);
 storeVariables = [[NSMutableArray alloc] init];
}

这是有效的： .h文件-

@interface ViewController2 : UIViewController{

    NSMutableArray *savedScoreData;
    int PlayTimer;
    int timeMinute;
    int bonusPts;
    int enemykill;

}

.m 文件-

- (void)viewDidLoad {

    PlayTimer = 0;
    timeMinute = 0;
    bonusPts = 0;
    timeMinute = 0;

    savedScoreData = [[NSMutableArray alloc] init];
}

- (IBAction)pauseButton:(id)sender {
    NSLog(@"pause-before: %d, %d, %d,",PlayTimer,enemykill,bonusPts);
    [GameTimer invalidate]; //this constantly changes the PlayTimer & timeMinute variables
    [characterTimer invalidate]; 
    [enemyTimer invalidate]; //this constantly changes the enemyKill & bonusPts variables
    [_bonusImgHolder removeFromSuperview];
    if([_soundEnable isEqualToString:@"YES"]){
        [_player2 pause];
    }
    //NSLog(@"%tu",_player2.playing);
    _resumeButton.hidden = NO;
    _pauseButton.hidden = YES;
    NSLog(@"pause-after: %d, %d, %d,",PlayTimer,enemykill,bonusPts);
    //[sender num :PlayTimer];
    [savedScoreData addObject:[NSNumber numberWithInteger: PlayTimer]];
    [savedScoreData addObject:[NSNumber numberWithInteger: timeMinute]];
    [savedScoreData addObject:[NSNumber numberWithInteger: enemykill]];
    [savedScoreData addObject:[NSNumber numberWithInteger: bonusPts]];
    NSLog(@"%i", [savedScoreData[0] intValue]);
    NSLog(@"%d", [savedScoreData[1] intValue]);
    NSLog(@"%d", [savedScoreData[2] intValue]);
    NSLog(@"%d", [savedScoreData[3] intValue]);

}
- (IBAction)resumeButton:(int)pauseButton{
    NSLog(@"resume-before: %d, %d, %d,",PlayTimer,enemykill,bonusPts);
    PlayTimer = [savedScoreData[0] intValue];
    timeMinute = [savedScoreData[1] intValue];
    enemykill = [savedScoreData[2] intValue];
    bonusPts = [savedScoreData[3] intValue];
    NSLog(@"%d", (int)enemykill);
    _resumeButton.hidden = YES;
    _pauseButton.hidden = NO;
    if([_soundEnable isEqualToString:@"YES"]){
        [_player2 play];
    }
    GameTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(CollectPoints) userInfo:nil repeats:YES];
    characterTimer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(Jumping) userInfo:nil repeats:YES];
    enemyTimer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(enemyTravel) userInfo:nil repeats:YES];
    NSLog(@"resume-after: %d, %d, %d,",PlayTimer,enemykill,bonusPts);
    [savedScoreData removeAllObjects];
}
