当应用程序在后台打开时获取警报消息.当我启动应用程序时从后台关闭应用程序时,它不会给我提示警报消息.当应用程序首次启动时,handleOpenURL无法在
JavaScript中调用.以下是代码
didFinishLaunchingWithOptions代码
NSURL* url = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey];
NSString* invokeString = nil;
if (url) {
invokeString = [url absoluteString];
NSLog(@"iPaperReeder launchOptions = %@",url);
}
self.viewController.invokeString = invokeString;
AppDelgate.m
if (!url) { return NO; }
NSString* jsString = [NSString stringWithFormat:@"window.setTimeout(function(){ handleOpenURL(\"%@\"); },1)",url];
[self.viewController.webView stringByEvaluatingJavaScriptFromString:jsString];
// all plugins will get the notification,and their handlers will be called
[[NSNotificationCenter defaultCenter] postNotification:[NSNotification notificationWithName:CDVPluginHandleOpenURLNotification object:url]];
return YES;
function handleOpenURL(url) {
alert('invoke: ' + url);
}
请帮我.
解决方法
我认为你做得不对,请按照我的代码如下：
您可以轻松解决此问题.
在“CDVHandleOpenURL.m”文件中,您需要更改以下代码：
NSString* jsString = [NSString stringWithFormat:@"document.addEventListener('deviceready',function(){if (typeof handleOpenURL === 'function') { handleOpenURL(\"%@\");}});",url];
至
NSString* jsString = [NSString stringWithFormat:@"if (typeof handleOpenURL === 'function') { handleOpenURL(\"%@\");} else { window._savedOpenURL = \"%@\"; }",url,url];
这将完美地运作.
祝你好运
