Here is my sample code:
SData *imageData = (NSData *)CFBridgingRelease(ABPersonCopyImageDataWithFormat(ref, kABPersonImageFormatThumbnail)) ;
CFStringRef firstName1, lastName1;
firstName1 = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
lastName1 = ABRecordCopyValue(ref, kABPersonLastNameProperty);
NSString *name=[[NSString alloc]init];
if ([[NSString stringWithFormat:#"%#",firstName1] isEqualToString:#"(null)"] && [[NSString stringWithFormat:#"%#",lastName1] isEqualToString:#"(null)"])
{
name = #"No Name";
}
else if([[NSString stringWithFormat:#"%#",firstName1] isEqualToString:#"(null)"] && ![[NSString stringWithFormat:#"%#",lastName1] isEqualToString:#"(null)"])
{
name = [NSString stringWithFormat:#"%#",lastName1];
}
else
{
name = [NSString stringWithFormat:#"%#",firstName1];
}
name= [ name capitalizedString];
EmailandCotactsModel *emailmodel=[[EmailandCotactsModel alloc]init];
emailmodel.emailemailstring=(__bridge NSString *)(contno);
emailmodel.emailusernamestring=name;
if(!imageData)
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"NoImage" ofType:#"png"];
NSData *photoData = [NSData dataWithContentsOfFile:path];
emailmodel.emailimagesData=photoData;
}
else
{
emailmodel.emailimagesData=imageData;
}
[emailarray addObject:emailmodel];
callsmsDataBool=NO;
NSLog(#"table email count %d and i %d",emailarray.count,tablecountint);
if(emailarray.count==tablecountint)
{
NSLog(#"table email reload");
tablecountint=tablecountint+10;
dispatch_async( dispatch_get_global_queue(0,0),^{
[self reloadtable];
});
NSLog(#"perform selection in bg");
}
}
}
[self.tableview reloadData];
if(!emailarray.count && [socialstring isEqualToString:#"Email"])
{
selectedlabel.text=#"Emails not found";
}
else if(emailarray.count && [socialstring isEqualToString:#"Email"])
{
// selectedlabel.text=#"Email";
selectedlabel.text=[NSString stringWithFormat:#"%ld",nPeople];
}
else if(!emailarray.count && [socialstring isEqualToString:#"SMS"])
{
selectedlabel.text=#"Phone no's not found";
}
else if(emailarray.count && [socialstring isEqualToString:#"SMS"])
{
selectedlabel.text=#"SMS";
}
else
{
selectedlabel.text=#"";
}
[tableview reloadData];
Any valuable suggestions will be appreciated....
Thanks in advance.

Answer 1

After getting all contacts in one array copy ten contacts to another array and cal table reload method with that new array by calling this method initially lowerlimit = 0 and upperlimit=10;
-(void)tabledataloadingmethod
{
for (lowerlimit=0+lowerlimit; lowerlimit<upperlimit; lowerlimit++)
{
if (lowerlimit<[self.array1 count])
{
OBJECT *obj=[self.array1 objectAtIndex:lowerlimit];
[self.array2 addObject:obj];
}
}
[self.tbleview reloadData];
}
in table delagete method cellforrowatindex use this
if ([self.array2 count]==indexPath.row)
{
UITableViewCell *cell1=[self.tbleview dequeueReusableCellWithIdentifier:#"cells"];
if(cell1==nil)
{
cell1=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"Cells"];
}
cell1.textLabel.textColor = [UIColor whiteColor];
cell1.textLabel.text=#"Loading more...";
[self performSelector:#selector(loadmorecells) withObject:nil afterDelay:0.2];
return cell1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if ([self.array2 count]>0 && ([self.array2 count]<[self.array1 count]))
{
return [self.array2 count]+1;
}
else
{
return [self.array2 count];
}
}
here we increment lowerlimit and upperlimit in loadmorecells method
-(void)loadmorecells
{
lowerlimit = upperlimit;
upperlimit = upperlimit +10;
[self tabledataloadingmethod];
}
