我在这里遇到了麻烦：我将应用程序设置为不在后台运行，并且我正在使用我在 github 上找到的 localNotification 插件设置 dailyInterval localnotification：https ://github.com/phonegap/phonegap-plugins /tree/master/iPhone/LocalNotification

当通知弹出时，应用程序崩溃了，我点击“查看”......看起来好像正在发送一些东西，但它不知道发生了什么。我也不知道发生了什么，因为 Objective C 对我来说是一门外语。有人有想法么？

好的，我发现了问题，它在文件 AppDelegate.m 中，更准确地说是在方法中：didFinishLaunchingWithOptions。该方法假定第一个选项参数是一个 url（但不是当我们通过本地通知启动应用程序时。快速而肮脏的解决方法是注释代码：

- (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];
}

如果有人感兴趣，我已经重新编写了 localNotification 插件 - 您现在可以添加回调和声音。我喜欢这个问题的修复，因为我遇到了同样的事情。我也将它包含在 GIT 项目中。

更好一点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 期望 URL 的键是什么，最好[keyArray objectAtIndex:0]用实际键替换部分。

我对本地通知也有类似的问题。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];
}
