iPhone + Twitter API：转换时间？ [英] iPhone + Twitter API: Converting time?

问题描述

从现在开始，有没有一种简单的方法可以将从twitter获得的时间戳转换为unix时间或分钟？我可以解析字符串并自己转换所有内容，但我希望有一种方法可以转换，不需要。下面是带有时间戳的created_at元素的示例。

Is there an easy way to convert the time stamp you get from twitter into unix time or minutes since now? I could parse through the string and convert everything myself but I'm hoping there is a way to convert that doesn't need that. Here is an example of a created_at element with a time stamp.

推荐答案

您可以使用NSDateFormatter，如下所示：

You can use NSDateFormatter with something like this :

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
[dateFormatter setLocale:usLocale]; 
[usLocale release];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
[dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4];

// see http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns
[dateFormatter setDateFormat: @"EEE MMM dd HH:mm:ss Z yyyy"];

NSDate *date = [dateFormatter dateFromString:[currentDict objectForKey:@"created_at"]];
[dateFormatter release];

NSTimeInterval seconds = [date timeIntervalSince1970];
