我尝试将日期格式设置如下：
NSDateFormatter *dformat = [[NSDateFormatter alloc]init];
[dformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];
NSDate *date = [dformat dateFromString:datestr];
But the date will be nil, so, can anyone tell me how to set the dateformat, thx!
但是日期将为零，所以，谁能告诉我如何设置日期格式，谢谢！

Try this:
尝试这个：
NSDateFormatter *dformat = [[NSDateFormatter alloc]init];
[dformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZ"];
NSDate *date = [dformat dateFromString:datestr];
Add ZZZto the end of your formatter.
添加ZZZ到格式化程序的末尾。

Try out this code
试试这个代码
NSString *datestr = @"2013-08-06T03:51:54+00:00";
NSDateFormatter *dformat = [[NSDateFormatter alloc]init];
[dformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssz"];
NSDate *date = [dformat dateFromString:datestr];
use small zwhere z give you - with the specific non-location format. Where that is unavailable, falls back to localized GMT format. Use one to three letters for the short format or four for the full format. In the short format, metazone names are not used unless the commonlyUsed flag is on in the locale
在 z 给你的地方使用小 z- 使用特定的非位置格式。如果不可用，则回退到本地化的 GMT 格式。短格式使用一到三个字母，完整格式使用四个字母。在短格式中，除非在 locale 中打开了 commonUsed 标志，否则不使用 metazone 名称

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyy-MM-dd'T'HH:mm:ssZ";
NSDate *date;
NSError *error;
[formatter getObjectValue:&date forString:dateString range:nil error:&error];
