好的，所以我的程序似乎运行良好并完成了我需要的所有计算，程序需要的最后一块是递增的切割清单。所以我尝试构建一个 NSMutable 数组并使用以前设置的变量，我最终将使用这些变量填充一个表。只有当我运行代码并点击计算按钮时，程序才会冻结，并且在 NSLOG 等中没有显示任何内容。我可以不使用在 for 循环之外设置的先前变量吗？还是怎么回事？

-(IBAction)calculateGo
{
    BuildNavAppDelegate *buildNavDelegate = (BuildNavAppDelegate *)[[UIApplication sharedApplication] delegate];

    float iridge = ([ridge.text intValue]);
    float ihip = ([hip.text intValue]);
    float ispacing = ([rafterSpace.text intValue]);

    float floatTLPMR = [buildNavDelegate.TLPMR floatValue];
    int floatRafter = [buildNavDelegate.raftThicknessPassed intValue];
    int comraftbird = [buildNavDelegate.comRaftBirdPassed intValue];

    float mitre = (45 * M_PI) / 180;
    float y = tanf(mitre);
    float mitreThickness = sqrt((y*y)+1) * ihip;

    float TLRafterSpace = (floatTLPMR * ispacing);

    float firstCreeper =  (TLRafterSpace + (mitreThickness/2))-(floatRafter/2);
    firstCreep.text = [[NSString alloc] initWithFormat:@"%.1f", firstCreeper];

    float comSetBack = floatTLPMR * (iridge/2);
    comRaftSetBack.text = [[NSString alloc] initWithFormat:@"%.1f", comSetBack];

    float crownSetBack = (floatTLPMR * (floatRafter/2));
    crownEndSetBack.text = [[NSString alloc] initWithFormat:@"%.1f", crownSetBack];

    creeperArray = [[NSMutableArray alloc] initWithCapacity:20];

for (int x = firstCreeper; x <= comraftbird; x + TLRafterSpace) {
[creeperArray addObject:[NSString stringWithFormat:@"%d", x]];
}
}

您陷入了无限循环，因为您忘记增加 的值x：

for (int x = firstCreeper; x <= comraftbird; x + TLRafterSpace)
                                             ^^^^^^^^^^^^^^^^^

那应该是：

for (int x = firstCreeper; x <= comraftbird; x += TLRafterSpace)
