这是我迄今为止的评论。 我使用了以下文字:toDateUsingFormat
, 使用了NSDateFormatter
, 载体上通过。 我不使用当地人,因为日期没有地方化。
if ( 0 == [string rangeOfString:@","].length ) {
result = [string toDateUsingFormat:@"d MMM y H:m:s z"];
} else {
result = [string toDateUsingFormat:@"E, d MMM y H:m:s z"];
}
Edit:
缩略语
NSDate *result = nil;
NSError *error = nil;
[dataFormatter getObjectValue:&result forString:dateString errorDescription:&error];
