尝试使用NSDate将NSTextField转换为字符串

Question

-(void)updateString

    {
        NSString * timeStampString = @"1316641549";
        NSTimeInterval _interval=[timeStampString doubleValue];
        NSDate *date = [NSDate dateWithTimeIntervalSince1970:_interval];
        NSLog(@"%@", date);

        [webView reload:0];
        [self.textField setStringValue:@"hi",date];
    }

有人能快点告诉我，我做错了什么吗？我试图将我的文本字段设置为等于我的日期，但[self.textField setStringValue:@"hi",date];返回“参数太多”格式化需要什么？ textField是一个NSTextField。谢谢！

Answer 1

NSString *dateString = [NSDateFormatter localizedStringFromDate:date 
                                                      dateStyle:NSDateFormatterShortStyle 
                                                      timeStyle:NSDateFormatterFullStyle];

[self.textField setStringValue:[NSString stringWithFormat:@"hi %@", dateString]];

Answer 2

NSString *Datestr = [NSDateFormatter localizedStringFromDate:[NSDate date] dateStyle:NSDateFormatterLongStyle timeStyle:NSDateFormatterMediumStyle];
