以编程方式请求访问联系人
以编程方式请求访问联系人
提问于 2012-09-29 06:37:54
自从更新到iPhone6之后，我注意到我将联系人添加到iOS地址簿的代码不再起作用。我认为这是一个与权限相关的问题，因为苹果现在需要用户权限才能访问联系人(修复this问题)。
我本以为这个应用会自动请求访问联系人的权限，就像下面的截图一样，但它没有。尝试添加联系人时出现ABAddressBookErrorDomain error 1失败。
是否需要以编程方式启动access to contacts request对话框？这是怎么做到的呢？

这对我来说是个完美的把戏！
在iOS6上，苹果引入了新的隐私控制，用户可以通过每个应用程序控制联系人和日历的访问。因此，在代码端，您需要添加一些方法来请求权限。在iOS5或更早的版本中，我们总是可以调用
ABAddressBookRef addressBook = ABAddressBookCreate();获取地址簿没有任何问题，但在iOS6中，如果你没有权限，这个调用将只返回空指针。这就是为什么我们需要更改方法来获取ABAddressBookRef的原因。
__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
accessGranted = granted;
dispatch_semaphore_signal(sema);
});
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
dispatch_release(sema);
}
else { // we're on iOS 5 or older
accessGranted = YES;
}
if (accessGranted) {
// Do whatever you want here.
}在代码中，信号量用于阻塞直到响应，而ABAddressBookRequestAccessWithCompletion将在应用程序之前没有请求的情况下请求许可。否则，它将只遵循设置-隐私-联系人中的设置。

对于联系人框架：
- (void)checkPermissionForCNContacts
{
switch ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts])
{
case CNAuthorizationStatusNotDetermined:
{
[[[CNContactStore alloc] init] requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES)
[self showCNContactPicker];
}];
}
break;
case CNAuthorizationStatusRestricted:
case CNAuthorizationStatusDenied:
// Show custom alert
break;
case CNAuthorizationStatusAuthorized:
[self showCNContactPicker];
break;
}
