Cordova iOS 3.7.0 handleOpenURL coldstart fix

cordova-ios-3.7.0-handleopenurl-fix

// I'm not saying this is the best solution, it's just a temp fix which works in my case to solve
//   the issue where a passed in url is not propagated to the handleOpenURL js function upon
//   coldstart on iOS Cordova 3.7.0.
//   Stay tuned on this issue for a better fix: https://issues.apache.org/jira/browse/CB-7606

// replace processOpenUrl in CDVViewController.m by this:

- (void)processOpenUrl:(NSURL*)url pageLoaded:(BOOL)pageLoaded
{
    NSString* readyState = [webView stringByEvaluatingJavaScriptFromString:@"document.readyState"];
    // for coldstart
    if (!pageLoaded) {
      pageLoaded = [readyState isEqualToString:@"interactive"];
    // for resume
    } else if ([readyState isEqualToString:@"loaded"] || [readyState isEqualToString:@"complete"]) {
      pageLoaded = true;
    }

    if (pageLoaded) {
      // calls into javascript global function 'handleOpenURL'
      NSString* jsString = [NSString stringWithFormat:@"if (typeof handleOpenURL === 'function') { handleOpenURL(\"%@\");}", url];
      [webView stringByEvaluatingJavaScriptFromString:jsString];
    } else {
        // save for when page has loaded
        self.openURL = url;
    }
}

// or replace it by this one which seems a bit more robust:
- (void)processOpenUrl:(NSURL*)url pageLoaded:(BOOL)pageLoaded
{
    if (!pageLoaded) {
        // query the webview for readystate
        NSString* readyState = [webView stringByEvaluatingJavaScriptFromString:@"document.readyState"];
        pageLoaded = [readyState isEqualToString:@"loaded"] || [readyState isEqualToString:@"complete"];
    }

    if (pageLoaded) {
        // calls into javascript global function 'handleOpenURL'
      dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 100 * NSEC_PER_MSEC), dispatch_get_main_queue(), ^{
        NSString* jsString = [NSString stringWithFormat:@"if (typeof handleOpenURL === 'function') { handleOpenURL(\"%@\");}", url];
        [webView stringByEvaluatingJavaScriptFromString:jsString];
      });
    } else {
        // save for when page has loaded
        self.openURL = url;
    }
}

Instead of messing with dispatch_after, I made a small patch that keeps track of the pageDidLoad callback, see https://gist.github.com/kapejod/85bd38cd74971741ee15
