NSDateFormatter与UTC无法正常工作 [英] NSDateFormatter not working properly with UTC

问题描述

我有以下日期：2011-04-29T14：54：00-04：00

I have the following date: 2011-04-29T14:54:00-04:00

当它运行以下代码时将其转换为日期，由于某种原因，日期为空：

When it runs through the following code to convert it to a date, the date is null for some reason:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZ"];
NSDate *date = [dateFormatter dateFromString:localDate];
[dateFormatter release];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-mm-dd"];
NSLog(@"%@", [formatter stringFromDate:date]);

任何帮助将不胜感激

已解决：

好的，我明白了。出于某种原因，此方法不起作用。

Ok, I figured it out. For some reason, this method doesn't work.

NSDate *date = [dateFormatter dateFromString:localDate];

这适用。希望它对某人有帮助！

This works instead. Hope it helps someone!

NSError *error = nil;
NSDate *date = nil;
[dateFormatter getObjectValue:&date forString:localDate range:nil error:&error];
