ios - PhoneGap/iOS LocalNotification 应用程序在点击时崩溃 "View"

Question

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。有人有什么想法吗？

好的，我发现了问题，它在文件 AppDelegate.m 中，更准确地说在方法中:didFinishLaunchingWithOptions。该方法假定第一个选项参数是一个 url(但当我们通过本地通知启动应用程序时它不是。快速而肮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];
}
