사이트 피드에서 읽고 UITableViewCell에 표시하는 작은 응용 프로그램을 작성했습니다. 사용자 정의보기 셀을 사용하고 내 UITableView 거꾸로 스크롤 매우 매끄럽지 않은 것처럼 스크롤에 망쳐 있습니다. 어떤 생각? 여기에 세포/데이터를 구축하지 세포 생성에, 초기화에 요청을 할 등 플러시 얻을로 dequeueReusableCellWithIdentifier 메소드를 호출 AFAIK 내있는 UITableViewCell에 대한 코드,iPhone UITableViewCell 성능 저하
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CustomCell";
CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
// cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil];
for(id currentObject in topLevelObjects) {
if([currentObject isKindOfClass:[UITableViewCell class]]) {
cell = (CustomCell *) currentObject;
break;
}
}
}
//MiceAppDelegate *AppDelegate = (MiceAppDelegate *)[[UIApplication sharedApplication] delegate];
if(dataArray != nil) {
//
//NSArray *promoArray = (NSArray *) promotions;
NSDictionary *datadict = [self.dataArray objectAtIndex:indexPath.row];
NSString *url = [datadict objectForKey:@"imageUrl"];
NSString *title = [datadict objectForKey:@"title"];
NSString *description = [datadict objectForKey:@"description"];
NSString *newAddressPartOfURL = [url stringByReplacingOccurrencesOfString:@" " withString:@"+"];
//NSLog([url stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]);
NSURLResponse *urlResponse;
NSData *data = [NSURLConnection sendSynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newAddressPartOfURL]] returningResponse:&urlResponse error:nil];
// Configure the cell.
UIImage *urlImage = [[UIImage alloc] initWithData:data];
// NSLog(@"%i",[imageView.image topCapHeight]);
cell.title.text = title;
cell.description.text = description;
cell.image.image = urlImage;
[urlImage release];
}
return cell;
}
