返回nil为dateFromString调用NSDateFormatter

Question

我得到nil为下面的代码中的日期变量返回。我无法找到日期格式的任何问题，任何人都可以帮忙吗？

NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; 
[formatter setDateFormat:@"EEE MMM dd HH:mm:ss zzz yyyy"]; 

NSString *dateString = [[NSString alloc] initWithFormat:@"%@", @"Mon Apr 05 04:37:28 UTC 2010"]; 
NSDate *date = [formatter dateFromString:dateString]; 

Answer 1

尝试

NSDate *date = [formatter dateFromString:@"Mon Apr 05 04:37:28 GMT 2010"]; 

或

NSDate *date = [formatter dateFromString:@"Mon Apr 05 04:37:28 +0000 2010"];
