Question

in the
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row==[self.peopleDataController countOfList]){
static NSString *CellIdentifier = #"LastMoreCell";
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;
moreButton = [[UIButton alloc] initWithFrame:CGRectMake(140, 2, 42, 42)];
[moreButton setImage:[UIImage imageNamed:#"more.png"] forState:UIControlStateNormal];
[moreButton addTarget:self action:#selector(showMoreRows:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:moreButton];
return cell;
}
}
-(void) showMoreRows:(id)sender {
MyAuraAppDelegate *delegate = (MyAuraAppDelegate *) [[UIApplication sharedApplication] delegate];
refreshlast = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
refreshSpinner.hidesWhenStopped = YES;
refreshlast.center = CGPointMake([[sender superview] superview].bounds.size.width / 2.0f, [[sender superview] superview].bounds.size.height / 2.0f);
[sender setHidden:YES];
[[sender superview].superview addSubview: refreshSpinner];
[refreshlast startAnimating];
dispatch_queue_t dloadQueue = dispatch_queue_create("People refresh", NULL);
dispatch_async(dloadQueue, ^{
if ([[[GlobalVariable sharedInstance] peopleList] count] >0) {
_peopleDataController = [_peopleDataController initPeopleListWithCoordinate:delegate.locationCoordinate2D auraId:delegate.myToken offset:0];
NSLog(#"eerrrr %d",_peopleDataController.peopleList.count);
// _peopleDataController.peopleList=[[GlobalVariable sharedInstance] peopleList];
for (int i=0; i< [_peopleDataController.peopleList count]; i++) {
[[[GlobalVariable sharedInstance] peopleList ] addObject:[_peopleDataController.peopleList objectAtIndex:i]];
}
_peopleDataController.peopleList =[[GlobalVariable sharedInstance] peopleList] ;
NSLog(#"eerrr33r %d",_peopleDataController.peopleList.count);
}
dispatch_async(dispatch_get_main_queue(), ^{
[self performSelector:#selector(addItem) withObject:nil afterDelay:2.0];
});
});
dispatch_release(dloadQueue);
}
but my UIActivityIndicatorView refresh last not show,can you give me some clue?

Answer 1

i found my mistake is :[sender superview].superview is the tabview not the tableviewcell
so last i modify my code:
-(void) showMoreRows:(id)sender {
UIButton *button=(UIButton*)sender;
MyAuraAppDelegate *delegate = (MyAuraAppDelegate *) [[UIApplication sharedApplication] delegate];
refreshlast = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
refreshSpinner.hidesWhenStopped = YES;
UITableViewCell *lastcell=(UITableViewCell*)[button superview];
refreshlast.center = CGPointMake(lastcell.frame.size.width / 2.0f, lastcell.frame.size.height / 2.0f);
NSLog(#"ddd %f",lastcell.frame.size.height);
[button setHidden:YES];
[lastcell addSubview:refreshlast];
[refreshlast startAnimating];
dispatch_queue_t dloadQueue = dispatch_queue_create("People refresh", NULL);
dispatch_async(dloadQueue, ^{
if ([[[GlobalVariable sharedInstance] peopleList] count] >0) {
_peopleDataController = [_peopleDataController initPeopleListWithCoordinate:delegate.locationCoordinate2D auraId:delegate.myToken offset:0];
NSLog(#"eerrrr %d",_peopleDataController.peopleList.count);
// _peopleDataController.peopleList=[[GlobalVariable sharedInstance] peopleList];
for (int i=0; i< [_peopleDataController.peopleList count]; i++) {
[[[GlobalVariable sharedInstance] peopleList ] addObject:[_peopleDataController.peopleList objectAtIndex:i]];
}
_peopleDataController.peopleList =[[GlobalVariable sharedInstance] peopleList] ;
NSLog(#"eerrr33r %d",_peopleDataController.peopleList.count);
}
dispatch_async(dispatch_get_main_queue(), ^{
[self performSelector:#selector(addItem) withObject:nil afterDelay:2.0];
});
});
dispatch_release(dloadQueue);
}
