ios项目开发（天气预报项目）

本项目基于 《使用storyboards建立 Navigation Controller and Table View》 http://uliweb.cpython.org/tutorial/view_chapter/424

创建， 代码中使用了 静态的 tableviewcell

增加了 textview,url,json数据解析

部分代码片段:

ViewController.m 增加

[objc]view plaincopyprint?

1. - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {  

2. if ([segue.identifier isEqualToString:@"cityinfo"]) {  

3. NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];  

4. UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];  

6. if ([[[cell textLabel] text] isEqualToString: @"北京"]) {  

7. NSError *error;  

8. NSURL *URL = [NSURL URLWithString:@"http://m.weather.com.cn/data/101010100.html"];  

9. NSData *data = [NSData dataWithContentsOfURL:URL];  

10. NSDictionary *Dic = [NSJSONSerialization JSONObjectWithData:data  

11. options:NSJSONReadingMutableContainers  

12. error:&error];  

14. NSDictionary *Info = [Dic objectForKey:@"weatherinfo"];  

16. cityViewController *destViewController = segue.destinationViewController;  

18.            destViewController.textcontent = [NSString stringWithFormat: @"今天是 %@  %@  %@  的天气状况是：%@  %@ ",[Info objectForKey:@"date_y"],[Info objectForKey:@"week"],[Info objectForKey:@"city"], [Info objectForKey:@"weather1"], [Info objectForKey:@"temp1"]];
