私はObjective-Cにかなり慣れていないのでUITableView
、非同期呼び出しの後に更新するのに問題があります。からデータが取り込まれたテーブル ビューがありNSMutableArray
ます。.net Web サービスからの JSON 応答から配列を設定します。wsdl2objc
Web サービスから JSON を取得するために使用しています。
これが私のコードです:
@interface NewsViewController : UITableViewController <ServiceSoapBindingResponseDelegate>
@property (nonatomic, strong) News *news;
@property (nonatomic, retain) NSMutableArray *newsList;
-(void) updateNewView:(NSMutableArray*) result;
-(void) loadNewsFromRemoteServer;
@end
-(void) viewDidLoad
{
_newsList = [[NSMutableArray alloc] init];
[self loadNewsFromRemoteServer];
[super viewDidLoad];
}
-(void) loadNewsFromRemoteServer
{
NSString *customerID = @"xxx";
NSString *uniqueID = @"xxx";
ServiceSoapBinding *bNews = [[ServiceSvc ServiceSoapBinding] retain];
bNews.logXMLInOut = YES;
ServiceSvc_GetNews *cRequest = [[ServiceSvc_GetNews new] autorelease];
cRequest.id_ = customerID;
cRequest.uniqueId = uniqueID;
[bNews GetNewsAsyncUsingParameters:cRequest delegate:self];
}
-(void) operation:(ServiceSoapBindingOperation *)operation completedWithResponse:(ServiceSoapBindingResponse *)response
{
NSArray *responseHeaders = response.headers;
NSArray *responseBodyParts = response.bodyParts;
NSMutableArray *newsListFromWebserver = [[NSMutableArray alloc] init];
for(id header in responseHeaders) {
// here do what you want with the headers, if there's anything of value in them
}
for(id bodyPart in responseBodyParts) {
if ([bodyPart isKindOfClass:[SOAPFault class]]) {
// You can get the error like this:
//NSLog(@"new list :: RESPONSE FROM SERVER :: %@",((SOAPFault *)bodyPart).simpleFaultString);
continue;
}
//Get News List
if([bodyPart isKindOfClass:[ServiceSvc_GetNewsResponse class]]) {
ServiceSvc_GetNewsResponse *body = (ServiceSvc_GetNewsResponse*)bodyPart;
NSString *nList = body.GetNewsResult; //JSON FORMAT
NSLog(@"new list :: RESPONSE FROM SERVER :: nList %@", nList);
NSDictionary *resultsDictionary = [nList objectFromJSONString] ;
for (NSDictionary * dataDict in resultsDictionary) {
News *newNews = [[News alloc] init];
_news = newNews;
_news.newsTitle = [NSString stringWithFormat:[dataDict objectForKey:@"Title"]];
_news.newsBody = [NSString stringWithFormat:[dataDict objectForKey:@"Body"]];
_news.newsDate = [NSString stringWithFormat:[dataDict objectForKey:@"NewDate"]];
[newsListFromWebserver addObject:_news];
[_news release];
}
}
}
[self performSelectorOnMainThread:@selector(updateNewView:) withObject:newsListFromWebserver waitUntilDone:NO];
[newsListFromWebserver release];
}
-(void) updateNewView:(NSMutableArray*) result
{
_newsList = result;
NSLog( @"new list - number of news :: %u", [_newsList count]);
[self.tableView reloadData];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
//Get the object from the array.
News *cNews = [_newsList objectAtIndex:indexPath.row];
cell.textLabel.text = cNews.newsDate;
cell.detailTextLabel.text = cNews.newsTitle;
cell.imageView.image = [UIImage imageNamed:@"bullet.png"];
return cell;
}
私のアプリケーションはこれをコンソールに記録します:
2012-09-08 22:36:45.463 xxx[45630:13a03] new list - number of news :: 1
2012-09-08 22:36:45.465 xxx[45630:13a03] *** -[__NSArrayM objectAtIndex:]: message sent to deallocated instance 0x79a3680
の呼び出しに失敗[_newsList objectAtIndex:indexPath.row]
しtableView:cellForRowAtIndexPath:
ます。何か助けはありますか?前もって感謝します
