队
我收到了服务器的回复日期。
"createTime": "2016-10-07T19:22:34.3192343+00:00"
根据日期更改,我想在设备上检查它(分钟,小时,天,月)。
是一种方法,如何计算完成时间?
基于服务请求"createTime" : "2016-10-07T19:22:34.3192343+00:00"
结果值应为30分钟。 2天后1:30分钟后1小时,这将是2天

NSString* format = @"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'";
// Set up an NSDateFormatter for UTC time zone
NSDateFormatter* formatterUtc = [[NSDateFormatter alloc] init];
[formatterUtc setDateFormat:format];
[formatterUtc setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
// Cast the input string to NSDate
NSDate* utcDate = [formatterUtc dateFromString:[formatterUtc stringFromDate:@""2016-10-07T19:22:34.3192343+00:00" "]];
// Set up an NSDateFormatter for the device's local time zone
NSDateFormatter* formatterLocal = [[NSDateFormatter alloc] init];
[formatterLocal setDateFormat:format];
[formatterLocal setTimeZone:[NSTimeZone localTimeZone]];
// Create local NSDate with time zone difference
NSDate* localDate = [formatterUtc dateFromString:[formatterLocal stringFromDate:utcDate]];
NSTimeInterval seconds = [[NSDate date] timeIntervalSinceDate:localDate];
