修剪 NSDate 以仅显示日期 [英] Trim NSDate to show date only

问题描述

我已经解决了所有类似的问题，不幸的是没有解决我的问题，所以我问了它.我需要我的函数返回一个 NSDate 和只有日期，但我的返回值也包含时间，我已经尝试了 setTimeStyle noStyle 和我能想出的所有可能的解决方案，这里是代码:

I have been through all the similar questions, unfortunately non could solve my problem so I asked it. I need my function to return an NSDate and only date, but my return value contains timing as well, I have tried the setTimeStyle noStyle and every possible solution I could come up with, here is the code:

-(NSDate*)stringToDate{
    NSString *dateString = @"01-02-2010";
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"dd-MM-yyyy"];
    NSDate *date;
    date = [dateFormatter dateFromString:dateString];
    NSLog(@"%@",date);
    return date;
} 

输出为:2010-01-31 16:00:00 +0000

我想要的:2010-01-31

推荐答案

这行不通，当您打印 NSDate 对象时，它将打印整个日期.从日期获取字符串表示的方式是使用 NSDateFormatter

This can't work, when you print a NSDate object it will print the ENTIRE date. the way you get a string representation from a date is by using a NSDateFormatter

NSDateFormatter *format = [[NSDateFormatter alloc] init];
format.dateFormat = @"dd-MM-yyyy";

NSLog(@"%@", [format stringFromDate:[NSDate new]]);

如果你愿意，你可以把它放在 NSDate 的一个类别中.

you can put this in a category on NSDate if you so desire.
