iOS8中的地址簿授权
自iOS 8更新以来，我有个问题需要获得访问AddressBook的权限。
在iOS 7中，系统询问用户我的应用程序是否被允许访问他的地址簿，但是自iOS8以来没有任何请求。 每次我在启动我的“MyGetAddressesOfContacts”函数之前检查ABAddressBookGetAuthorizationStatus，状态等于kABAuthorizationStatusNotDetermined。 就像你可以在这里看到的：
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusDenied)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No permission" message:@"This App has no permition to access your contacts. Please check it in your privacy settings of your device." delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
return nil;
}
// This AlertView pops up every time!
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Why this App needs your contacts" message:@"In the following your device will ask you whether this App is allowed to access your contacts. [...]" delegate:self cancelButtonTitle:@"I understand" otherButtonTitles: nil];
[alert show];
}
在此检查后，我将开始MyGetAddressesOfContacts功能，如下所示：
ABAddressBookRef addressBook = ABAddressBookCreate();
NSArray *contactArr = (NSArray *)CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook));
NSMutableDictionary *dPersons = [[NSMutableDictionary alloc] init];
for (int i = 0; i < [contactArr count]; i++)
{
ABRecordRef person = (ABRecordRef)CFBridgingRetain([contactArr objectAtIndex:i]);
NSString *firstName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);
NSString *lastName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonLastNameProperty);
NSString *sPersonName = [NSString stringWithFormat:@"%@ %@", firstName, lastName];
ABMultiValueRef address = ABRecordCopyValue(person, kABPersonAddressProperty);
NSString *sAddress;
for(CFIndex j = 0; j < ABMultiValueGetCount(address); j++)
{
CFDictionaryRef addressDict = ABMultiValueCopyValueAtIndex(address, j);
CFStringRef streetValue = CFDictionaryGetValue(addressDict, kABPersonAddressStreetKey);
CFStringRef cityValue = CFDictionaryGetValue(addressDict, kABPersonAddressCityKey);
CFStringRef countryValue = CFDictionaryGetValue(addressDict, kABPersonAddressCountryKey);
sAddress = [NSString stringWithFormat:@"%@ %@, %@", streetValue, cityValue, countryValue];
[dPersons setObject:sAddress forKey: [NSString stringWithFormat:@"%@%d %ld", @"AddressFromNameID", i, j]];
}
[dPersons setObject:sPersonName forKey: [NSString stringWithFormat:@"%@ %d", @"NameWithID", i]];
}
return dPersons;
希望有人能帮忙。
创建AB之后...
ABAddressBookRef addressBook = ABAddressBookCreate();
请拨打以下电话...
ABAddressBookRequestAccessWithCompletion(addressBook, nil);
这将显示提示让用户允许您的应用程序访问“联系人”; 作为第二个参数，您可能会得到结果回调并相应地执行操作。 请参阅Apple文档
