How to communicate other installed ios apps & pass text

// SENDER SIDE

-(IBAction) openReceiverApp:(id)sender {

// Opens the Receiver app if installed, otherwise displays an error

UIApplication *ourApplication = [UIApplication sharedApplication];

NSString *str= @”Pass text to receiver App” ;

NSString *URLEncodedText = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSString *ourPath = [@”ReceiverAppText://” stringByAppendingString:URLEncodedText];

NSURL *ourURL = [NSURL URLWithString:ourPath];

if ([ourApplication canOpenURL:ourURL]) {

[ourApplication openURL:ourURL];

}

else {

//Display error

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@”Receiver Not Found” message:@”The Receiver App is not installed. It must be installed to send text.” delegate:nil cancelButtonTitle:@”OK” otherButtonTitles:nil];

[alertView show];

[alertView release];

}

}

// RECEIVER SIDE

In the Project Navigator, expand the Supporting Files group and open the Receiver-Info.plist file.

You can add a new row by going to the menu and clicking Editor > Add Item. Set up a URL Types item by adding a new item. Expand the URL Types key, expand Item 0, and add a new item, “URL schemes”. Fill in “ReceiverAppText” for Item 0 of “URL schemes” and your company identifier for the “URL Identifier”.

 

& to catch the text from sender app, you have to implement a provided method of ios,

 

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

    // Display text
    UIAlertView *alertView;
    NSString *text = [[url host] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    alertView = [[UIAlertView alloc] initWithTitle:@"Text" message:text delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];
    [alertView release];
    return YES;
}
Thats it !
