我有以下for循环：
func test(_ fourHundredYears: [CountPatternPair]) {
// Iterate over `CountPatternPairs` containing hundred-year `CountPatternPairs`
for hundredYearCPP in fourHundredYears {
// Do the below as many times as indicated by the count in the `CountPatternPair`
for _ in 1 ... hundredYearCPP.0 {
// Iterate over `CountPatternPairs` containing four-year `CountPatternPairs`
for fourYearCPP in (hundredYearCPP.1 as! [CountPatternPair]) {
// Do the below as many times as indicated by the count in the `CountPatternPair`
for _ in 1 ... fourYearCPP.0 {
// Iterate over `CountPatternPairs` containing year `CountPatternPairs
for yearCPP in (fourYearCPP.1 as! [CountPatternPair]) {
// Do the below as many times as indicated by the count in the `CountPatternPair`
for _ in 1 ... yearCPP.0 {
// Iterate over each month in the array element of the `CountPatternPair`
for month in (yearCPP.1 as! [[DayTotalPair]]) {
// Iterate over each `DayTotalPair` in each month
for dtp in month {
oeod.append(dtp.1, over: dtp.0)
i += dtp.0
if minLimit.equals(oeod.at(oeod.count - 1)) { return }
}
}
}
}
}
}
}
}
}
我写了这个怪物来测试一些逻辑，目的是当逻辑正常工作时，我会将它重构为递归函数以使其更清晰。我做到了，但递归版本不起作用。想我错过了什么，但最终我把它搁置了，因为我一生都看不到它是什么。仍在测试中，我决定将一些循环逻辑提取到它们自己的函数中，以使其更清晰。不添加任何新逻辑。从我看来，不改变任何逻辑的执行顺序。
但令我沮丧的是，重构为单个功能的相同功能也不起作用。直接复制粘贴，还是不行。尝试使用该extract to功能Xcode以防是我的复制和粘贴破坏了它，但也没有用。
有人可以看一下上面代码的以下提取版本，看看是否有任何事情会导致它执行与上面不同的逻辑？
func iterateFourHundredYears(_ fourHundredYears: [CountPatternPair]) {
// Iterate over `CountPatternPairs` containing hundred-year `CountPatternPairs`
for hundredYearCPP in fourHundredYears {
iterateHundredYearCPP(hundredYearCPP)
}
}
func iterateHundredYearCPP(_ hundredYearCPP: CountPatternPair) {
// Do the below as many times as indicated by the count in the `CountPatternPair`
for _ in 1 ... hundredYearCPP.0 {
// Iterate over `CountPatternPairs` containing four-year `CountPatternPairs`
for fourYearCPP in (hundredYearCPP.1 as! [CountPatternPair]) {
iterateFourYearCPP(fourYearCPP)
}
}
}
func iterateFourYearCPP(_ fourYearCPP: CountPatternPair) {
// Do the below as many times as indicated by the count in the `CountPatternPair`
for _ in 1 ... fourYearCPP.0 {
// Iterate over `CountPatternPairs` containing year `CountPatternPairs
for yearCPP in (fourYearCPP.1 as! [CountPatternPair]) {
iterateYearCPP(yearCPP)
}
}
}
func iterateYearCPP(_ yearCPP: CountPatternPair) {
// Do the below as many times as indicated by the count in the `CountPatternPair`
for _ in 1 ... yearCPP.0 {
// Iterate over each month in the array element of the `CountPatternPair`
for month in (yearCPP.1 as! [[DayTotalPair]]) {
// Iterate over each `DayTotalPair` in each month
for dtp in month {
oeod.append(dtp.1, over: dtp.0)
i += dtp.0
if minLimit.equals(oeod.at(oeod.count - 1)) { return }
}
}
}
}
