问题描述

嗨我想创建一个天气应用程序.我的天气应用程序是这样的，当用户单击天气"选项卡时，应在表格视图中显示当前位置的天气详细信息.对于相同的当前位置，当天，第二天和第二天的天气详细信息第二天之后应该显示在tableview.please任何人给我任何形式的代码或任何链接，关于如何在iphone中. 谢谢

解决方案

您将不得不使用NSDate，

首先使用当前时间构建一个NSDate对象

NSDate *today = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"HH:mm:ss"];
NSString *currentTime = [dateFormatter stringFromDate:today];
[dateFormatter setDateFormat:@"dd.MM.yyyy"];
NSString *currentDate = [dateFormatter stringFromDate:today];

现在currentDate是字符串对象，您可以在屏幕上用UILabel显示它，

同样，您可以创建日期并获取第二天的字符串对象.

WeatherAPI

这些不是特定于iPhone的，而是免费的天气API.

解决方案

You will have to use NSDate ,

First Construct an NSDate object with current time

NSDate *today = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"HH:mm:ss"];
NSString *currentTime = [dateFormatter stringFromDate:today];
[dateFormatter setDateFormat:@"dd.MM.yyyy"];
NSString *currentDate = [dateFormatter stringFromDate:today];

Now currentDate is the string object, you can display it with UILabel on screen,

likewise you could create date and get the string object for Next day .....
