如何在PhoneGap中处理自定义URL方案以进行冷启动？

问题描述

我使用handleOpenURL（）作为自定义网址计划，从电子邮件中的链接启动我的应用程序。工作完美，我可以根据链接中的网址参数在我的应用程序。

I'm using handleOpenURL() for a Custom URL Scheme to launch my app from a link in an email. Works perfectly and I can do stuff in my app based on the URL parameters in the link.

问题是handleOpenURL（）似乎没有得到调用，当我的应用程序做冷启动（不在后台运行）。是否有其他处理程序可用于冷启动与已运行的实例？

The problem is handleOpenURL() doesn't seem to get call when my app does a cold start (not running in the background). Is there another handler that I can use for a cold start vs an already running instance?

或

有一个全局变量，我可以读，将告诉我什么调用URL是？

Is there a global variable that I can read that will tell me what the invoke URL was? I read about invokeString, but it never seems to be set?

我正在使用PhoneGap 2.0

推荐答案

如果仔细阅读应用程序上面的注释：handleOpenURL方法，您可能会理解：

if you read carefully the comment above the application:handleOpenURL method, you will probably understand:

// this happens while we are running ( in the background, or from within our own app )
// only valid if Calinda-Info.plist specifies a protocol to handle
- (BOOL) application:(UIApplication*)application handleOpenURL:(NSURL*)url

没有运行。我的解决方案是调整项目与以下更改：

This methods will not be called if the application is not running. My solution was to tweak project with the following changes:

MainViewController.h

MainViewController.h

@interface MainViewController : CDVViewController
@property (nonatomic, retain) NSString *URLToHandle;
@end

MainViewController.m

MainViewController.m

- (void) webViewDidFinishLoad:(UIWebView*) theWebView
{
     if (self.URLToHandle)
     {
         NSString* jsString = [NSString stringWithFormat:@"window.setTimeout(function() {handleOpenURL(\"%@\"); },1);", self.URLToHandle];
         [theWebView stringByEvaluatingJavaScriptFromString:jsString];
     }
     [...]
}

- (void)dealloc
{
    self.URLToHandle = nil;
    [super dealloc];
}

@synthesize URLToHandle;

AppDelegate.m

AppDelegate.m

- (BOOL) application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    [...]
    self.viewController = [[[MainViewController alloc] init] autorelease];
    self.viewController.useSplashScreen = YES;
    self.viewController.wwwFolderName = @"www";
    self.viewController.startPage = @"index.html";
    self.viewController.view.frame = viewBounds;

    // Patch for handleOpenURL
    ((MainViewController *)self.viewController).URLToHandle = URLToHandle;

    [...]
}

另外注意：测试时确保停止xcode。当xcode运行应用程序将抛出异​​常。如果我停止xcode这个解决方案工作正常。

Additional note: when testing make sure you stop xcode. When xcode was running application would throw an exception. if I stop the xcode this solution works fine.
