ios項目開發（天氣預報項目）

本項目基於 《使用storyboards建立 Navigation Controller and Table View》 http://uliweb.cpython.org/tutorial/view_chapter/424

創建， 代碼中使用了 靜態的 tableviewcell

增加了 textview,url,json數據解析

部分代碼片段:

//
//  cityViewController.h
//  weather1
//

//
#import <UIKit/UIKit.h>
@interface cityViewController : UIViewController
@property (strong, nonatomic) IBOutlet UITextView *text1;
@property (strong, nonatomic) IBOutlet NSString *textcontent;
@end

- (void)viewDidLoad
{
    [super viewDidLoad];
self.text1.text= textcontent;
// Do any additional setup after loading the view.
}

//
//  ViewController.h
//  weather1

@interface ViewController : UITableViewController
@end

ViewController.m 增加

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"cityinfo"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

if ([[[cell textLabel] text] isEqualToString: @"北京"]) {
NSError *error;
NSURL *URL = [NSURL URLWithString:@"http://m.weather.com.cn/data/101010100.html"];
NSData *data = [NSData dataWithContentsOfURL:URL];
NSDictionary *Dic = [NSJSONSerialization JSONObjectWithData:data
 options:NSJSONReadingMutableContainers
 error:&error];

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

cityViewController *destViewController = segue.destinationViewController;

            destViewController.textcontent = [NSString stringWithFormat: @"今天是 %@  %@  %@  的天氣狀況是：%@  %@ ",[Info objectForKey:@"date_y"],[Info objectForKey:@"week"],[Info objectForKey:@"city"], [Info objectForKey:@"weather1"], [Info objectForKey:@"temp1"]];

        }
    }
}
