我怎样才能在ios中获得当地时区？

Question

我需要根据ios设备的位置设置本地时区.

[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]]; 

要么

[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"GTC+5.30"]]; 

适合吗？

Answer 1

// get current date/time
NSDate *today = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// display in 12HR/24HR (i.e. 11:25PM or 23:25) format according to User Settings
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
NSString *currentTime = [dateFormatter stringFromDate:today];
[dateFormatter release];
NSLog(@"User's current time in their preference format:%@",currentTime);

您可以使用以下命令获取本地时区的名称:

NSTimeZone *timeZone = [NSTimeZone localTimeZone];
NSString *tzName = [timeZone name];
