如何让iphone时间

Question

可以帮助在通过iPhone应用程序

Answer 1

NSDate *today = [NSDate date]; 

找到iphone的时间，让您有当前时间和日期。

Answer 2

NSDate *today = [NSDate date]; 

NSCalendar *calendar= [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 
NSCalendarUnit unitFlags = NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit; 
NSDateComponents *dateComponents = [calendar components:unitFlags fromDate:today]; 

[calendar release];  

NSInteger hour = [dateComponents hour]; 
NSInteger min = [dateComponents minute]; 
NSInteger sec = [dateComponents second]; 

这实际上只是从日期开始，而不是整个日期。它在不同的整数中获得时间，hour,min,sec。在手机的底部

NSString *time = [NSString stringWithFormat:@"%i:%i:%i", hour, min, sec];
