私は自分のプロジェクトで TFHpple を使用しようとしています。これがそのコードです...理解するのはかなり簡単です:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSURL *url = [NSURL URLWithString:@"http://v1.myurl.com/somemethod"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request startAsynchronous];
}
- (void)viewDidUnload
{
[self setGpMapView:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSString *responseString = [request responseString];
// Use when fetching binary data
NSData *responseData = [request responseData];
TFHpple *doc = [[TFHpple alloc] initWithXMLData:responseData];
NSArray *elements = [doc searchWithXPathQuery:@"/entry"];
NSLog(@"count: %@",[elements count]);
}
- (void)requestFailed:(ASIHTTPRequest *)request
{
NSError *error = [request error];
}
その間に、http 要求呼び出しを行うために asihttp ライブラリも使用しています。コンソールで null が表示されます。xml をもう一度確認しました。タグが確実に存在することはわかっています。何か方法はありますか?
