Objective-C将NSDate设置为当前UTC [英] Objective-C setting NSDate to current UTC

问题描述

是否有一种简单的方法可以使用当前的UTC日期/时间初始化 NSDate ？

Is there an easy way to init an NSDate with the current UTC date/time?

推荐答案

[NSDate date];

您可能想要创建一个类别类似这样的事情：

You may want to create a category that does something like this:

-(NSString *)getUTCFormateDate:(NSDate *)localDate
{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
    [dateFormatter setTimeZone:timeZone];
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    NSString *dateString = [dateFormatter stringFromDate:localDate];
    [dateFormatter release];
    return dateString;
}
