UIAlertView with a lot of buttons seems destroyed iOS 6 - ios

Question

There is an issue with an UIAlertView when i add to this a lot of buttons. Then the alertView seems to be destroyed. This happens only to prior version of iOS 7. On iOS 7 and posterior versions it seems ok.Here is a screenshot of my problem.Can i fix it?
- (void) sortTotalMnhmeia{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Ταξινόμηση" message:#"Επιλέξτε είδος ταξινόμησης" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Αξιοθέατα",#"Δραστηριότητες",#"Διαμονή",#"Χωριά",#"Προϊόντα",#"Όλες οι κατηγορίες",nil];
[alert show];
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0)
{
NSLog(#"Cancel Tapped.");
}
else if (buttonIndex == 1)
{
[self.mapView removeAnnotations:self.annotations];
[self.annotations removeAllObjects];
self.annotations=[[NSMutableArray alloc] init];
NSLog(#"yo %d",self.annotations.count);
for(int i=0; i<self.allGroups.count; i++){
Group *assistantGroup=assistantGroup=[self.allGroups objectAtIndex:i];
if ([assistantGroup.secondLevel intValue]==1) {
if ([assistantGroup.thirdLevel intValue]==1) {
self.chooseMarker=#"Museum";
}
else if ([assistantGroup.thirdLevel intValue]==2) {
self.chooseMarker=#"Art";
}
else if ([assistantGroup.thirdLevel intValue]==3) {
self.chooseMarker=#"Religious";
}
else if ([assistantGroup.thirdLevel intValue]==4) {
self.chooseMarker=#"Monument";
}
else if ([assistantGroup.thirdLevel intValue]==5) {
self.chooseMarker=#"Natural";
}
else if ([assistantGroup.thirdLevel intValue]==6) {
self.chooseMarker=#"Beach";
}
NSLog(#"************ %# %# %#",assistantGroup.title,assistantGroup.latitude,assistantGroup.longitude);
Annotation *ann = [[Annotation alloc] initWithLong:[assistantGroup.longitude doubleValue] Lat:[assistantGroup.latitude doubleValue] iconNumber:0];
ann.title = assistantGroup.title;
ann.subtitle=#"";
ann.type=self.chooseMarker;
[self.annotations addObject:ann];
}
//ann.type=assistantGroup.kind;
}
[self.mapView addAnnotations:self.annotations];
}
.....
}

You should consider using a modal view controller instead since using lots of buttons in an AlertView can be confusing. I don't see the reason adding lots of buttons to a single alert view. A modal VC has all the flexibility you are looking for. Otherwise an action sheet would be preferable too.
But to answer the question: Add a "More" button last that spawns a second AlertView with the buttons that don't fit the first alert view. Alert VCs don't rescale the way they do on iOS versions above 7.0.
