Antonio GarcĂa commented on CB-8028: ------------------------------------ I have the same problem with v3.7.0 & iOS 8.1. When the app is closed the {{(void)processOpenUrl:(NSURL*)url pageLoaded:(BOOL)pageLoaded}} method is called a first time from this stack trace: {code} 0 -[CDVViewController processOpenUrl:pageLoaded:] at CDVViewController.m:1011 1 -[CDVViewController processOpenUrl:] at CDVViewController.m:1030 2 -[AppDelegate application:openURL:sourceApplication:annotation:] at AppDelegate.m:102 3 -[UIApplication _applicationOpenURL:payload:] () 4 -[UIApplication _callInitializationDelegatesForMainScene:transitionContext:] () 5 -[UIApplication _runWithMainScene:transitionContext:completion:] () 6 -[UIApplication workspaceDidEndTransaction:] () 7 __31-[FBSSerialQueue performAsync:]_block_invoke () 8 __CFRUNLOOP_IS_CALLING_OUT_TO_A_BLOCK__ () 9 __CFRunLoopDoBlocks () 10 __CFRunLoopRun () 11 CFRunLoopRunSpecific () 12 -[UIApplication _run] () 13 UIApplicationMain () 14 main at ./UrlSchema/platforms/ios/UrlSchema/main.m:32 15 start () {code} As {{pageLoaded == NO}} then {{document.readyState}} is evaluated {code} NSString* readyState = [webView stringByEvaluatingJavaScriptFromString:@"document.readyState"]; {code} At this moment the DOM isn't loaded, but the problem is that {{readyState}} returns "complete" and {{pageLoaded}} changes to YES. Therefore the javascript {{handleOpenURL}} invocation fails. A possible solution would be to check the existence of the {{handleOpenURL}} function within the DOM: {code} if (!pageLoaded) { // query the webview for readystate NSString* readyState = [webView stringByEvaluatingJavaScriptFromString:@"document.readyState"]; pageLoaded = ([readyState isEqualToString:@"loaded"] || [readyState isEqualToString:@"complete"]); if(pageLoaded){ pageLoaded = [[webView stringByEvaluatingJavaScriptFromString:@"(typeof handleOpenURL === 'function')"] boolValue]; } } {code} > handleOpenURL doesn't work properly when app is being launched for the first > time > --------------------------------------------------------------------------------- > > Key: CB-8028 > URL: https://issues.apache.org/jira/browse/CB-8028 > Project: Apache Cordova > Issue Type: Bug > Components: iOS > Affects Versions: 3.7.0 > Reporter: Antonio Laguna > Assignee: Shazron Abdullah > > Hi! > Please bear in mind that this is my first issue being reported here but I > thought it to be worth it. > So, we've been developing a Cordova application lately and we decided to add > a notification center plugin to be able to launch the application from it, > taking advantage of the url-scheme on iOS. > We discovered that it worked flawlessly when it was launched and the app was > in background but it wasn't when the app was closed and tried to launch from > there. > So I dug deeper. > Since this is an Ionic application, I thought the issue was due to Angular > not being ready at the appropriate time or something like that so I just put > something really low-level which didn't depend on any library: > {code:javascript} > window.foo = 'bar'; > {code} > And then checked with a timeout (after app was ready) to see if it was there. > But it wasn't. > So I dug deeper. > So the issue seems to come on this function which is on the > {{CDDViewController}} class > {code} > - (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' > NSString* jsString = [NSString stringWithFormat:@"if (typeof > handleOpenURL === 'function') { handleOpenURL(\"%@\");}", url]; > [self.webView stringByEvaluatingJavaScriptFromString:jsString]; > } else { > // save for when page has loaded > self.openURL = url; > } > } > {code} > The thing is that the second check for {{pageLoaded}} is positive even though > the page is clearly at a really early stage.
