ios - 今天上午10点到达

Question

今天上午10点和明天上午10点在ios？

NSDateComponents *nowComponents = [calendar components:NSYearCalendarUnit | NSWeekCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit fromDate:today];

[nowComponents setHour：10];

这没有给出适当的回应。我怎么能这样做？

Answer 1

试试这段代码，希望它能运作。如果您希望明天获得10 am，请将小时设置为34。

NSDate *date = [NSDate date];
NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
[gregorian setTimeZone:gmt];
NSDateComponents *components = [gregorian components: NSUIntegerMax fromDate: date];
[components setHour: 10];
[components setMinute:0];
[components setSecond: 0];
NSDate *newDate = [gregorian dateFromComponents: components];
NSLog(@"Date%@", newDate);
[gregorian release];
