This is how I request contacts framework access permission
-(void)askUserToAccessContacts
{
@try
{
if([CNContactStore class])
{
//iOS 9 or later
CNEntityType entityType = CNEntityTypeContacts;
if( [CNContactStore authorizationStatusForEntityType:entityType] == CNAuthorizationStatusNotDetermined)
{
CNContactStore * contactStore = [[CNContactStore alloc] init];
[contactStore requestAccessForEntityType:entityType completionHandler:^(BOOL granted, NSError * _Nullable error) {
if(granted){
DDLogVerbose(@"Permission granted for Contacts access...");
}
}];
}
else if( [CNContactStore authorizationStatusForEntityType:entityType]== CNAuthorizationStatusAuthorized)
{
DDLogVerbose(@"Permission granted for Contacts access !!!");
}
else
{
DDLogVerbose(@"Permission not granted for Contacts access !!!");
}
}
} @catch (NSException *exception) {
[[WriteLogger getWriteLogger] writeLog:@"AppDelegate" sourceClass:NSStringFromClass([self class]) methodName:NSStringFromSelector(_cmd) exception:exception exceptionDict:nil];
}
}
What could possibly cause the app to crash?
By the way, this crash is not occurring all the time, it happens randomly when I install the app and launch it for the first time.
