我正在使用 Apple 的新框架加载联系人。
-(void)getAllContactsWithNewFrameworkOfApple {
NSMutableArray *_contactsArray = [[NSMutableArray alloc]init];
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusDenied) {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:@"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can use contacts" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]];
// [self presentViewController:alert animated:TRUE completion:nil];
return;
}
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
// make sure the user granted us access
if (!granted) {
dispatch_async(dispatch_get_main_queue(), ^{
// user didn't grant access;
// so, again, tell user here why app needs permissions in order to do it's job;
// this is dispatched to the main queue because this request could be running on background thread
});
return;
}
NSError *fetchError;
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactIdentifierKey,CNContactGivenNameKey,CNContactFamilyNameKey,CNContactEmailAddressesKey,CNContactPhoneNumbersKey]];
BOOL success = [store enumerateContactsWithFetchRequest:request error:&fetchError usingBlock:^(CNContact *contact, BOOL *stop) {
[_contactsArray addObject:contact];
NSLog(@"I am %@", _contactsArray);
}];
if (!success) {
NSLog(@"error = %@", fetchError);
}else {
NSLog(@"End with Success %@", _contactsArray);
[self finalUsage:_contactsArray];
}
}];
}
最终使用这个数组并加载到 TableView 上的第二种方法是......
-(void) finalUsage: (NSMutableArray*)_contactsArray {
items = [[NSMutableArray alloc] init];
for (CNContact *contact in _contactsArray) {
_contact = [[Contacts alloc] init];
_contact.contactNumber = [[NSMutableArray alloc] init];
_contact.email = [[NSMutableArray alloc] init];
NSLog(@"I am Given Name is %@", contact.givenName);
NSLog(@"I am Given Name is %@", contact.familyName);
_contact.fName = contact.givenName;
_contact.lName = contact.familyName;
for (CNLabeledValue * emailValue in contact.emailAddresses){
NSString *emailString = emailValue.value;
NSString *emailLabel = emailValue.label;
NSLog(@"Contact is %@, %@", emailString, emailLabel);
[_contact.email addObject:emailString];
}
NSLog(@"\n\n\n...");
for (CNLabeledValue<CNPhoneNumber*> * phoneValue in contact.phoneNumbers){
NSString *phoneString =phoneValue.value.stringValue;
NSString *phoneLabel = phoneValue.label;
NSLog(@"Contact is phone %@ %@", phoneString,phoneLabel);
[_contact.contactNumber addObject:phoneString];
}
NSLog(@"\n\n\n");
[items addObject:_contact];
NSLog(@"no. of items in array %li",(unsigned long)items .count);
}
[self.tableData removeAllObjects];
_tableData = items;
[self updateSectionTiles];
_tableData = [self partitionObjects:_tableData collationStringSelector:@selector(fName)];
[_tableview_contacts setDelegate:self];
[_tableview_contacts setDataSource:self];
[_tableview_contacts reloadData];
}
现在它给出了错误
This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes. This will cause an exception in a future release.

并且使用谷歌的深度错误方法是

我怎么知道该块是结束，还是简单的编译处理程序？
如果我调用块的最后一行中的方法，它会在块结束之前调用。
任何指导帮助？
