iphone - 如何获取 iPhone 项目的 UTC 时间？

Question

如何在 iPhone 开发中获取我所在国家/地区的 UTC 时间？

Answer 1

这是代码，当你想设置时区和日期格式时，只需调用下面的方法即可。

-(void)setDateFormat
{
     NsDate myDate = [NSDate date];//here it returns current date of device.
    //now set the timeZone and set the Date format to this date as you want.
     NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
     NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
     [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
     [dateFormatter setTimeZone:timeZone];
     NSString *newDate = [dateFormatter stringFromDate:myDate];
    // here you have new Date with desired format and TimeZone.
}
