ios - iOS - Dayofweek 函数返回错误的值

Question

DayOfWeek功能工作不正常。[NSDate date]，而准确，导致TimeHour错误。我举个例子，[NSDate date]DayOfWeek的值为 5，第二天我设置的 TimeHour 不值 6。你可以看到下面的代码块：

NSDateFormatter *dateFormatterHour = [[NSDateFormatter alloc]init];
[dateFormatterHour setDateFormat:@"dd-mm-yyyy H:mm"];
NSDate *TimeHour = [dateFormatterHour dateFromString:_textAlisTarih.text];

//NSDateComponents *components = [[NSCalendar currentCalendar] components:NSWeekdayCalendarUnit fromDate:[NSDate date]]; // is True;

NSDateComponents *components = [[NSCalendar currentCalendar] components:NSWeekdayCalendarUnit fromDate:TimeHour]; // is False;
int weekday = [components weekday];
NSLog(@"weekday: %i",weekday);
