show contact images along with contact name in tableview - iphone

Question

I want to show phone contacts along with the pic in table view in alphabetic order.
I have managed to show contact name in correct order but unable to show images in correct order.
I have been trying these for few days but couldn't succeed .
I know how to sort array but don't know how to sort the image data.
please help me guys.
here is my demo code:
NSArray *sortedFirstNames;
- (void)getPersonDetails
{
CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);
if (addressBook != nil)
{
NSLog(#"Succesful.");
NSArray *allContacts = (__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
NSUInteger i = 0;
NSMutableArray *firstNames = [[NSMutableArray alloc] init];
NSMutableArray *firstimages = [[NSMutableArray alloc] init];
for (i = 0; i < [allContacts count]; i++)
{
Person *person = [[Person alloc] init];
ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
NSString *lastName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);
NSString *fullName;
if (lastName == nil)
{
fullName = [NSString stringWithFormat:#"%#", firstName];
[firstNames addObject: fullName];
}
else if(firstName ==nil)
{
fullName = [NSString stringWithFormat:#"%#", lastName];
[firstNames addObject: fullName];
}
else
{
fullName = [NSString stringWithFormat:#"%# %#", firstName, lastName];
[firstNames addObject: fullName];
}
person.firstName = firstName;
person.lastName = lastName;
person.fullName = fullName;
//email
imgdata=(__bridge NSData*)ABPersonCopyImageDataWithFormat(contactPerson, kABPersonImageFormatThumbnail);
NSLog(#"newstris%#",imageStr);
if(imgdata==nil)
{
}
else
{
[firstimages addObject:imgdata];
}
[self.tableData addObject:person];
}
sortedFirstNames = [firstNames sortedArrayUsingSelector:#selector(localizedCaseInsensitiveCompare:)];
}
CFRelease(addressBook);
}
code for showing images in cell:
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
dispatch_async(queue, ^{
UIImage *image1;
// cell.imageView.frame = CGRectMake(0, 0, 50, 50);
if (person.imgdata==nil) {
image1=[UIImage imageNamed:#"default_profile_pic.jpg"];
}
else
{
image1 = [UIImage imageWithData:person.imgdata];
}
UIImageView *imageView = [[UIImageView alloc] initWithImage:image1];
imageView.frame = CGRectMake(6.5, 6.5, 45., 45.);
dispatch_sync(dispatch_get_main_queue(), ^{
[cell addSubview:imageView];
});
});
Thanks..

Answer 1

Answer is pretty simple.
Add a field in your Person class which stores a NSData.
Like:
#property (nonatomic, strong) NSData *imageData;
And use:
person.imageData = imgdata;

Answer 2

I too faced same issue. I have fixed this issue by associate object like this.
while loading source array:
objc_setAssociatedObject(hDetails, #"imageUrl", record, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
in cell for row at indexpath :
Record *record = objc_getAssociatedObject(hDetails,#"imageUrl");
for more reference see this :
How do I use objc_setAssociatedObject/objc_getAssociatedObject inside an object?
