ios - 我们可以打开 watch 扩展上的联系人吗

Question

如何在 watch 扩展中以编程方式打开 iPhone 的联系人，就像我们在 iOS 中使用地址簿一样。

提前致谢

Answer 1

通常从您使用的 WatchKit 扩展与 iPhone 通信

+ (BOOL)openParentApplication:(NSDictionary *)userInfo reply:(void(^)(NSDictionary *replyInfo, NSError *error)) reply;    // launches containing iOS application on the phone. userInfo must be non-nil

WKInterfaceController的方法类(class)。

因此，例如，您可以将 Storyboard中按钮的 IBAction 附加到此方法

- (IBAction)callPhoneAppButtonTapped
{
    NSDictionary *dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:@"text to display on iPhone", @"key", nil];

    [InterfaceController openParentApplication:dictionary reply:^(NSDictionary *replyInfo, NSError *error) {
        NSLog(@"Reply received by Watch app: %@", replyInfo);
    }];
}

注:为了从通讯簿中获取数据，用户需要授予您的应用权限。但应用程序将在后台启动，用户将专注于 Watch，因此最好在您的 iPhone 应用程序中请求此权限。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
        ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL,  nil), ^(bool granted, CFErrorRef error) {
    if (!granted){
        NSLog(@"Access denied");
        return;
    }
    NSLog(@"Access granted");
});
}

为了处理 openParentApplication:reply 发送的消息在您的 AppDelegate 实现中

- (void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
    NSLog(@"Request received by iOS app");
    NSDictionary *dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:@"your value to return to Apple Watch", @"key", nil];

    // Here your app will be launch in background. Fetch AddressBook or other data you need.
    // Remember to call reply block in the end.  

    // Example of saving data to Address Book
    NSString *firstName;
    NSString *lastName;

    firstName = @"Maggie";
    lastName = @"Peggie";

    ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, nil);
    ABRecordRef contact = ABPersonCreate();

    ABRecordSetValue(contact, kABPersonFirstNameProperty, (__bridge CFStringRef) firstName, nil);
    ABRecordSetValue(contact, kABPersonLastNameProperty, (__bridge CFStringRef)lastName, nil);

    ABAddressBookAddRecord(addressBookRef, contact, nil);
    ABAddressBookSave(addressBookRef, nil);

    reply(dictionary);
}
