如何将NSDate格式化程序与日期数组一起使用? [英] How to use NSDate formatter with an array of dates?

问题描述

我正在尝试从当前日期开始生成一个30天的数组，并将它们放入格式正确的数组中.我目前有一个正在运行的生成器，可以从当前日期起30天并将其放入数组中，但是我不知道如何为数组使用NSDate格式化程序.我知道如何对单个项目使用格式化程序，但是如何格式化数组中的所有日期?我想要的格式是(月日).这是我的代码:

I'm trying to generate an array of 30 days from the current date and put them into an array formatted correctly. I currently have a working generater to get 30 days from the current date and put it into an array but I don't know how to use NSDate formatter for an array. I know how to use the formatter for a single item but how can I format all the dates in my array? The format that I would like is (Month Day). Here's my code:

NSMutableArray* dates = [[NSMutableArray alloc] init];
    int numberOfDays=30;
    NSDate *startDate=[NSDate date];
    NSDate *tempDate=[startDate copy];
    for (int i=0;i<numberOfDays;i++) {
        NSLog(@"%@",tempDate.description);
        tempDate=[tempDate dateByAddingTimeInterval:(60*60*24)];
        [dates addObject:tempDate.description];
    }

    NSLog(@"%@",dates);

谢谢您的任何帮助.

推荐答案

像这样使用，

NSMutableArray* dates = [[NSMutableArray alloc] init];
    int numberOfDays=30;
    NSDate *startDate=[NSDate date];
    NSDate *tempDate=[startDate copy];
    for (int i=0;i<numberOfDays;i++) {
        NSLog(@"%@",tempDate.description);
        tempDate=[tempDate dateByAddingTimeInterval:(60*60*24)];
     NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"MM/dd"];
    NSString *dateString = [dateFormat stringFromDate:tempDate];
    tempDate=[dateFormat dateFromString:dateString];
    [dateFormat release];

        [dates addObject:tempDate.description];
    }

    NSLog(@"%@",dates);
