Question

How to detect an arrived SMS in code? and how can I auto check if it contains specific strings? for example I wanna send SMS to the Iphone which contains “specifString” and I want the receiver Iphone auto open my app.

Answer 1

You cannot, get a notification when a person receives a SMS, but you can enter a special url in that SMS that then would launch your application when clicked.

In your Info.plist you have to define some key-value pairs:

And then your app is launched when url like this is clicked:

yourapp://?foo=1&bar=2

as you can see, you can pass parameters to your app.

In your app you get a special event, when your app is launched from an url.

4.1 and earlier:

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 
{
  // Do something with the url here
}

**4.2 and later **

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
    // Do something with the url here
}
