Ios 天数循环中的整数在所有天数内继续重复

ios objective-c

Ios 天数循环中的整数在所有天数内继续重复,ios,objective-c,int,nsdate,nsnumber,Ios,Objective C,Int,Nsdate,Nsnumber,我已经尝试过多次更改获取一天开始/一天结束日期的函数，并且我知道循环正在工作，因为它打印出了一周中正确的几天，但是出于某种原因，每天的开始和结束时间戳显示相同。它必须是与int无关的东西，或者是与我看不到的逻辑没有直接关系的东西： 下面是它打印出来的内容： WEEK_ARRAY:{ Friday = { "DAY_END" = 1454389199; "DAY_START" = 1454302800; }; Monday =

[格式化程序setDateFormat:@“EEEE”]；

对于（int i=0；i而言，原因是
beginingofday
和
endOfDay
方法中缺少
NSDayCalendarUnit
组件。
在beginingofday和endOfDay函数中，您错过了NSCalendarUnitDay。此外，在ios8中也不推荐使用NSMonthCalendarUnit、NSYearCalendarUnit

哇，代码太多了。我相信大部分都可以扔掉。例如，为什么每天都有一个
开始日期：
方法，而你可以从今天开始，每次迭代减去一整天？请不要判断，现在是凌晨3点。我只是在寻找答案。为什么重复这么多？！“不要判断”呵呵。你来错地方了。请不要。不要在凌晨3点写代码。如果你不那么累的话，明天整理代码所花的时间将比一开始写代码所花的时间要多。请看瓦迪安的帖子。这与另一个答案没有太大区别。你应该在另一个answ中添加一条关于不赞成的评论呃。这对时间戳有效，但现在我意识到由于某种原因，日期不符合顺序？查看日志，它给了我星期五、星期一、星期六、星期日？这是因为字典的定义是无序的。如果要保留顺序，请使用数组并将工作日添加到字典中。
