PhoneGap / iOS LocalNotification应用程序在点击“查看”时崩溃

我在这里遇到麻烦：我将应用程序设置为不在后台运行，并且我使用我在github上找到的localNotification插件设置dailyInterval本地通知： https ： //github.com/phonegap/phonegap-plugins /树/主/ iPhone / LocalNotification

当通知弹出时应用程序崩溃，我点击“查看”…看起来正在发送的东西，它不知道发生了什么。 我，也不知道是什么，因为Objective C对我来说是一门外语。 有人有主意吗？

Answer 1

好的，我发现了问题，它位于文件AppDelegate.m中，更确切地说是在方法中：didFinishLaunchingWithOptions。 该方法假设第一个选项参数是一个url（但是当我们通过本地通知启动应用程序时，它不是。快速和脏的修复是注释代码：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //commented out because it makes the app crash at startup with local notification... /*NSArray *keyArray = [launchOptions allKeys]; if ([launchOptions objectForKey:[keyArray objectAtIndex:0]]!=nil) { NSURL *url = [launchOptions objectForKey:[keyArray objectAtIndex:0]]; self.invokeString = [url absoluteString]; NSLog(@"Mosa_fr_en-busi launchOptions = %@",url); }*/ return [super application:application didFinishLaunchingWithOptions:launchOptions]; } 

Answer 2

如果有人有兴趣，我会重新编写localNotification插件 – 你现在可以添加回调和声音。 我喜欢这个问题，因为我遇到了同样的问题。 我也把它包含在GIT项目中。

一个更好的解决方案是这样的：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSArray *keyArray = [launchOptions allKeys]; if ([keyArray count] > 0) { id option = [launchOptions objectForKey:[keyArray objectAtIndex:0]]; if ([option isKindOfClass:[NSURL class]]) { NSURL *url = (NSURL *)option; self.invokeString = [url absoluteString]; NSLog(@"ContactInbox launchOptions = %@",url); } } return [super application:application didFinishLaunchingWithOptions:launchOptions]; } 

如果有人知道PhoneGap对URL有什么关键，那么用实际键替换[keyArray objectAtIndex:0]部分会更好。

我在本地通知时遇到了类似的问题。 我选择的解决方案有点不同（尽管非常相似）。 我正在使用检查本地通知启动选项（UIApplicationLaunchOptionsLocalNotificationKey）。

这是一个简短的例子：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey]; if( localNotif ) { // Do whatever you need to do with that local notitication } else { NSArray *keyArray = [launchOptions allKeys]; if ([launchOptions objectForKey:[keyArray objectAtIndex:0]]!=nil) { NSURL *url = [launchOptions objectForKey:[keyArray objectAtIndex:0]]; self.invokeString = [url absoluteString]; } } return [super application:application didFinishLaunchingWithOptions:launchOptions]; }
