Question

我正在制作一个骰子游戏。我有5个骰子。我将它们全部滚动以获得所有5个骰子的随机值。我添加了每个骰子，并在标签上打印出8“sumTotal”。

我想知道每次用户点击按钮时如何将每个值“sumTotal”存储到数组中。
我想知道一旦我打印出8号总数。如何删除它，并将下一个值添加到标签的开头。

谢谢

    self.die1Value = (arc4random() % 6) + 1;
    self.die2Value = (arc4random() % 6) + 1;

    self.die4Value = (arc4random() % 6) + 1;

您可以将总计存储在数组中。以下代码存储总计，在8个总计之后，再次从数组的开头开始。

@property (strong,nonatomic) NSMutableArray totals;
@property NSInteger arrayPointer;

-(void)viewDidLoad {
     [super viewDidLoad];
     self.totals=[NSMutableArray new];
     self.arrayPointer=0;
}


- (IBAction)rollDice:(id)sender {

self.die1Value = (arc4random() % 6) + 1;
self.die2Value = (arc4random() % 6) + 1;
self.die3Value = (arc4random() % 6) + 1;
self.die4Value = (arc4random() % 6) + 1;
self.die5Value = (arc4random() % 6) + 1;

[self.dieOne setTitle:[NSString stringWithFormat:@"%li",(long)self.die1Value ] forState:UIControlStateNormal];
[self.dieTwo setTitle:[NSString stringWithFormat:@"%li",(long)self.die2Value ] forState:UIControlStateNormal];
[self.dieThree setTitle:[NSString stringWithFormat:@"%li",(long)self.die3Value ] forState:UIControlStateNormal];
[self.dieFour setTitle:[NSString stringWithFormat:@"%li",(long)self.die4Value ] forState:UIControlStateNormal];
[self.dieFive setTitle:[NSString stringWithFormat:@"%li",(long)self.die5Value ] forState:UIControlStateNormal];

NSInteger sumTotal = self.die1Value + self.die2Value + self.die3Value + self.die4Value + self.die5Value;

[self addTotalToArray:sumTotal];


if (self.numberOfLines <= 8) {
  //  if (self.numberOfLines <= 8) {
    NSString *i = [NSString stringWithFormat:@"\nTotal is: %d", self.sumTotal];
    self.totalLabelIt.text = [self.totalLabelIt.text stringByAppendingString:i];

    if (self.numberOfLines > 8) {
        //  if (self.numberOfLines <= 8) {
        NSString *i = [NSString stringWithFormat:@"\nTotal issss: %d", self.sumTotal];
        self.totalLabelIt.text = [self.totalLabelIt.text stringByAppendingString:i];

    }

}

-(void) addTotalToArray:(NSInteger) total {
    NSNumber totalNum=[NSNumber numberWithInteger:total];
    if (self.arrayPointer > self.totals.count-1) {
        [self.totals addObject:totalNum];
    } else {
        self.totals[self.arrayPointer]=totalNum;
    }

    if (++self.arrayPointer == 8) { 
        self.arrayPointer=0;
    }
}

正如我在评论中所说，我建议您使用数组来驱动UITableView，而不是试图操纵标签

在点击UI按钮时将值输入到数组中
