javascript - How to call some Objective C code in a PhoneGap app on startup?

Question

I have a PhoneGap app up and running using JavaScript and HTML.

On app startup I need to run some Objective C code (I don't know anything about Objective C. I just have some code that I need to copy + paste so it runs when the app starts).

Where do I put that code in my Phonegap project? Is there some kind of event listener or a main function?

Answer 1

在您的 AppDelegate.m 文件中查找名为：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //ADD YOUR OBJECTIVE-C CODE HERE
    return YES;
}

另一种可能的选择：

您可能还有其他类，例如 XXXViewController.h/.m。如果是这种情况，请检查是否有一个方法称为：

- (void)viewDidLoad
{
    [super viewDidLoad];
    //INSERT YOUR OBJECTIVE-C CODE HERE.
}

Answer 2

您需要使用插件。通过这样做，您可以创建本机目标 C 类，然后从 PhoneGap 中的 Javascript 调用它们。
