我打電話給web服務從xcode 4編寫.net輸出是一個json字符串.when該調用與URL使用靜態ip地址它給出error.HTTP錯誤404.0 - 未找到。但工作時相同的URL被稱爲localhost.the代碼如下從xcode獲取json

- (void)viewDidLoad 
{  
    [super viewDidLoad]; 
    NSURL *url=[NSURLURLWithString:@"http:// static ip address where serviceis located(169.254.216.8)/restGroceryService/WebService/insertList?prods=apples,bananas,milk"]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
    NSData *data = [NSData dataWithContentsOfURL:url]; 
    NSString *pageSource = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
    NSLog(@"page source%@",pageSource); 
    NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil]; 
    NSArray *array = [json objectForKey:@"result"]; 
    NSDictionary *store = [array objectAtIndex:0]; 
    NSNumber *storeId = [store objectForKey:@"storeId"]; 
    NSNumber *total = [store objectForKey:@"TOTAL"]; 
    self.priceTextField.text =[total stringValue]; 
    NSString *storeName = [store objectForKey:@"storeName"]; 
    self.storNameTextField.text = storeName; 
}

爲什麼有這麼多的新行被賦予？你喜歡滾動嗎？ – 2012-07-10 19:41:46

我認爲您使用的是本地IP，並且您嘗試使用3G網絡訪問它。它不會工作。您必須連接到本地wifi或使用外部IP地址。 – George 2012-07-10 20:59:26

NSURL *url=[NSURL URLWithString:@"your address"];/<------ here was the error 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
    NSData *data = [NSData dataWithContentsOfURL:url]; 
    NSString *pageSource = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
    NSLog(@"page source%@",pageSource); 
    NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil]; 
    NSArray *array = [json objectForKey:@"result"]; 
    NSDictionary *store = [array objectAtIndex:0]; 
    NSNumber *storeId = [store objectForKey:@"storeId"]; 
    NSNumber *total = [store objectForKey:@"TOTAL"]; 
    self.priceTextField.text =[total stringValue];
