iphone - ios - 获取今天上午 10 点

Question

如何在 ios 中获取今天上午 10 点和明天上午 10 点？

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

[nowComponents setHour:10];

这没有给出正确的回应。我该怎么做？

尝试一下这段代码，希望它能起作用。如果您想获取明天的上午 10 点，请将时间设置为 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];
