apple-push-notifications - 适用于 Adob​​e Air 的推送通知 iOS native 扩展

Question

我正在为 Adob​​e AIR 开发 iOS native 扩展，它将获取推送通知的设备 token 。不幸的是，我不是那种喜欢 objective-C 的程序员，我不确定我使用的代码是否有问题。它编译没有问题，我可以将扩展与 AIR 一起使用，但看起来注册通知不会返回正面或负面影响。所以我想做的是在从 AIR 调用 RegisterDevice 函数时注册通知，如果它确实注册，则将设备 token 存储在 deviceTokenString 中，如果它没有注册并返回错误，我将错误存储在此字符串中.当调用 GetToken 函数时，我将 deviceTokenString 返回给 AIR，因此它是 token 或错误。在 AIR 应用程序中，我首先启动 RegisterDevice 函数，然后通过单击按钮启动 GetToken 函数。不幸的是，我既没有得到 token 也没有得到错误(也没有出现请求许可的弹出窗口)。我也试图将注册部分放在 didFinishLaunchingWithOptions 中，但看起来 didFinishLaunchingWithOptions 从未启动过。如果你们能看看代码是否可以，我将非常感激。或者，也许您有任何想法还有什么可能是错误的？我在配置门户中启用了推送 SSL 证书。这是我正在使用的代码

Answer 1

好的，

在撕掉我的头发 3 天后，我弄明白了。我没有设置代表，因为那会破坏 Adob​​e 的所有东西。我创建了现有委托(delegate)的自定义子类，并覆盖了与 APNS 相关的委托(delegate)函数。我的代码如下。

//empty delegate functions, stubbed signature is so we can find this method in the delegate
//and override it with our custom implementation
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{}

    - (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error{}


   //custom implementations of empty signatures above
void didRegisterForRemoteNotificationsWithDeviceToken(id self, SEL _cmd, UIApplication* application, NSData* deviceToken)
{
NSLog(@"My token is: %@", deviceToken);
}


 void didFailToRegisterForRemoteNotificationsWithError(id self, SEL _cmd, UIApplication* application, NSError* error)
{
NSLog(@"Failed to get token, error: %@", error);
}





// ContextInitializer()
//
// The context initializer is called when the runtime creates the extension context instance.
void PushContextInitializer(void* extData, const uint8_t* ctxType, FREContext ctx, 
                    uint32_t* numFunctionsToTest, const FRENamedFunction** functionsToSet) 
{

//injects our modified delegate functions into the sharedApplication delegate

id delegate = [[UIApplication sharedApplication] delegate];

Class objectClass = object_getClass(delegate);

NSString *newClassName = [NSString stringWithFormat:@"Custom_%@", NSStringFromClass(objectClass)];
Class modDelegate = NSClassFromString(newClassName);
if (modDelegate == nil) {
    // this class doesn't exist; create it
    // allocate a new class
    modDelegate = objc_allocateClassPair(objectClass, [newClassName UTF8String], 0);

    SEL selectorToOverride1 = @selector(application:didRegisterForRemoteNotificationsWithDeviceToken:);

    SEL selectorToOverride2 = @selector(application:didFailToRegisterForRemoteNotificationsWithError:);

    // get the info on the method we're going to override
    Method m1 = class_getInstanceMethod([jreporterNativePush class], selectorToOverride1);
    Method m2 = class_getInstanceMethod([jreporterNativePush class], selectorToOverride2);

    // add the method to the new class
    class_addMethod(modDelegate, selectorToOverride1, (IMP)didRegisterForRemoteNotificationsWithDeviceToken, method_getTypeEncoding(m1));

    class_addMethod(modDelegate, selectorToOverride2, (IMP)didFailToRegisterForRemoteNotificationsWithError, method_getTypeEncoding(m2));

    // register the new class with the runtime
    objc_registerClassPair(modDelegate);
}
// change the class of the object
object_setClass(delegate, modDelegate);


NSLog(@"completed crazy swap w/o bombing  w00t");

///////// end of delegate injection / modification code



*numFunctionsToTest = 1;

FRENamedFunction* func = (FRENamedFunction*) malloc(sizeof(FRENamedFunction) * 1);

func[0].name = (const uint8_t*) "registerPush";
func[0].functionData = NULL;
func[0].function = &registerPush;

*functionsToSet = func;
