每当我使用“println(buildDateString("xx","xx","xx","xx","xx")"调用我的 buildDateString 方法时，我的应用程序崩溃，给我错误消息“线程 1:断点 4.1 "
import Foundation

func getDateFromString(dateString: String) -> NSDate? {
var dateFormatter: NSDateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy-kk-mm-ss"

return dateFormatter.dateFromString(dateString)
}
func getCurrentDateAsArray() -> [Int] {
var dateFormatter: NSDateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy-kk-mm-ss"

var dayValue = day
var monthValue = month
var hourValue = hour
var minuteValue = minute
var secondValue = second
var currentDate = getCurrentDateAsArray()
println(currentDate)
dayValue = dayValue.utf16Count == 1 ? "0" + dayValue : dayValue
monthValue = monthValue.utf16Count == 1 ? "0" + monthValue : monthValue
hourValue = hourValue.utf16Count == 1 ? "0" + hourValue : hourValue
minuteValue = minuteValue.utf16Count == 1 ? "0" + minuteValue : minuteValue
secondValue = secondValue.utf16Count == 1 ? "0" + secondValue : secondValue
var bool1 = monthValue.toInt() > currentDate[0]
var bool2 = monthValue.toInt() == currentDate[0] && dayValue.toInt() > currentDate[1]
var bool3 = monthValue.toInt() == currentDate[0] && dayValue.toInt() == currentDate[1] && hourValue.toInt() > currentDate[3]
var bool4 = monthValue.toInt() == currentDate[0] && dayValue.toInt() == currentDate[1] && hourValue.toInt() == currentDate[3] && minuteValue.toInt() > currentDate[4]
var bool5 = monthValue.toInt() == currentDate[0] && dayValue.toInt() == currentDate[1] && hourValue.toInt() == currentDate[3] && minuteValue.toInt() == currentDate[4] && secondValue.toInt() > currentDate[5]
if (bool1 || bool2 || bool3 || bool4 || bool5) {
currentDate[2] = currentDate[2] + 1
}
var currentDateStringArray: [String] = [monthValue, dayValue, "\(currentDate[2])", hourValue,minuteValue, secondValue]
return "-".join(currentDateStringArray)
}
我不明白为什么会这样，而且 xCode 也没有给我任何关于错误可能是什么的提示。
我正在使用带有 xCode 6.2 beta 4 的 iOS 8.2 SDK
错误被抛到这一行:
println(buildDateString("12", "5", "12", "12", "7"))
