get total hours from nsdate

问题

I'm just looking for a method that calculates the total hours from nsdate (does the same as the TotalHours method in .net)

example : 11:30:30 -> 11.5 hours

Thanks in advance,

回答1:

Get the hour and minute separated with NSDateComponents.

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:[NSDate date]];
NSInteger hour = [components hour];
NSInteger minute = [components minute];

Then use this to find the sum.

double totalHours = ((double)hour + (double)minute/60);
