Only a limited number of contacts are displayed on a mobile device, compared to a PC
I'm uploading a map. And I add pins to the map based on the address of the contacts in the address book. I have some weird cases where some contacts (maybe 2 out of 10) are not thrown onto the card. I have verified the address which is valid. But the pin doesn't fall off. What could be the reason for this.
for (i = 0; i<[groupContentArray count]; i++) {
person = ABAddressBookGetPersonWithRecordID(addressbook,[[groupContentArray objectAtIndex:i] intValue]);
ABMultiValueRef addressProperty = ABRecordCopyValue(person, kABPersonAddressProperty);
NSArray *address = (NSArray *)ABMultiValueCopyArrayOfAllValues(addressProperty);
NSLog(@"Address %@", address);
for (NSDictionary *addressDict in address)
{
addAnnotation = nil;
firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
NSString *country = [addressDict objectForKey:@"Country"];
NSString *streetName = [addressDict objectForKey:@"Street"];
NSString *cityName = [addressDict objectForKey:@"City"];
NSString *stateName = [addressDict objectForKey:@"State"];
if (streetName == (id)[NSNull null] || streetName.length == 0 ) streetName = @"";
if (stateName == (id)[NSNull null] || stateName.length == 0 ) stateName = @"";
if (cityName == (id)[NSNull null] || cityName.length == 0 ) cityName = @"";
if (country == (id)[NSNull null] || country.length == 0 ) country = @"";
NSString *fullAddress = [streetName stringByAppendingFormat:@"%@/%@/%@", cityName, stateName, country];
mapCenter = [self getLocationFromAddressString:fullAddress];
if(stateName != NULL || country != NULL || streetName != NULL || cityName != NULL){
if ((mapCenter.latitude == 0) && (mapCenter.longitude == 0))
{
// Alert View
}
else{
addAnnotation = (MyAddressAnnotation *)[mapView dequeueReusableAnnotationViewWithIdentifier:[groupContentArray objectAtIndex:i]];
if(addAnnotation == nil){
addAnnotation = [[[MyAddressAnnotation alloc] initWithCoordinate:mapCenter title:firstName SubTitle:lastName Recordid:[groupContentArray objectAtIndex:i] ]autorelease];
[mapView addAnnotation:addAnnotation];}
}
}
}
CFRelease(addressProperty);
}
Edit: I am editing my question and will be more specific. I am using code to delete contacts on my mapView. On my Mac PC if 20 contacts are dropped on the card. All 20 pins drop accurately and work fine. But when I use IPhone or iPad, the number of contacts decreases. That is, out of 20 pins that I throw, only 4 contacts are displayed on the map. I cannot understand the reason for this.

This code:
else {
addAnnotation = (MyAddressAnnotation *)[mapView dequeueReusableAnnotationViewWithIdentifier:[groupContentArray objectAtIndex:i]];
if (addAnnotation == nil) {
addAnnotation = [[[MyAddressAnnotation alloc] initWithCoordinate:mapCenter title:firstName SubTitle:lastName Recordid:[groupContentArray objectAtIndex:i] ]autorelease];
[mapView addAnnotation:addAnnotation];
}
}
doesn't make sense.
The method dequeueReusableAnnotationViewWithIdentifier
is for deleting object MKAnnotationView
objects - not id<MKAnnotation>
.
The dequeuing code belongs to the delegate method viewForAnnotation
anyway, not here.
Here you should just create your annotation objects ( MyAddressAnnotation
) and call addAnnotation
them.
I also highly recommend that you change the name of your annotation variable from addAnnotation
to something else so you can't confuse it with the map view method addAnnotation
.
