Current Week Start and End Date

由 我与影子孤独终老i 提交于 2019-12-28 01:55:12
问题 I want to get the current week start and end date and I also want to use the previous week start and end date and next week of the start and end date in current month. Thanks in Advance. 回答1: rangeOfUnit:startDate:interval:forDate:. It gives you the start and the interval for a certain time unit. With it it is easy to find the start of the week in the used calendar and add the range-1 to get the latest second in that week. NSCalendar *cal = [NSCalendar currentCalendar]; NSDate *now = [NSDate

c++学习总结：获取13位系统时间戳

由 大憨熊 提交于 2019-12-27 21:19:12
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 在iOS中使用NSDate来处理时间相关的操作，这在iOS客户端开发中非常方便。如果中间层使用c++来写的话，为了保证中间层代码的纯净，不能在c++中混编OC代码，这时候就要使用c++的方法来产生13位时间戳，向外传递给OC调用，如下代码展示了如何生成13位时间戳的方式， #if defined(__APPLE__) #define sprintf_s snprintf #endif time_t t = time(NULL); char timeInterval[32] = {0}; sprintf_s(timeInterval, sizeof(timeInterval), "%ld000", t); //timeInterval即为13位的时间戳。 这时候timeInterval即为c++中间层传递给OC的13位时间戳，将其转换成OC时间的方法乳腺下所示， //将中间层传过来的c++时间戳strtime转换成iOS中的时间 NSDateFormatter *formatter =[[NSDateFormatter alloc] init]; [formatter setDateFormat:@"MM/dd HH:mm"]; //atol()将const char*字符串转换为长整形long NSDate

Number of days between two NSDates [duplicate]

由 一世执手 提交于 2019-12-27 09:00:10
问题 This question already has answers here : Objective C - calculating the number of days between two dates (6 answers) Closed 4 years ago . How could I determine the number of days between two NSDate values (taking into consideration time as well)? The NSDate values are in whatever form [NSDate date] takes. Specifically, when a user enters the inactive state in my iPhone app, I store the following value: exitDate = [NSDate date]; And when they open the app back up, I get the current time: NSDate

Why is my timer counting down by 3 every second?

由 一个人想着一个人 提交于 2019-12-26 15:22:45
问题 I have a timer that's counting down by 3. I'm triggering the timer in the viewDidLoad method where I'm also querying time variables from Parse. Here's my code where the timer function is: var createdAt = object.createdAt if createdAt != nil { let calendar = NSCalendar.currentCalendar() let comps = calendar.components([.Hour, .Minute, .Second], fromDate: createdAt as NSDate!) let hour = comps.hour * 3600 let minute = comps.minute * 60 let seconds = comps.second self.timerInt.append(hour +

How can I create an array of certain times?

由 眉间皱痕 提交于 2019-12-25 20:38:13
问题 I want to create an array of times and than sort through them to find when the next closest time in the array is (if it passes a time, then it will choose the next one as next closest). How can I do this? I don't want it to specify year, month, or day. I just want to filter through the time of day (hours, minutes, seconds). I would like to get how many seconds until the next time in the NSArray . I have looked at NSDate and noticed there is a timeIntervalSinceDate method but I do not know how

Currently your logic
