[英]iOS App crashes when launched from local notification
我已經為我的應用設置了每日提醒本地通知。 該應用程序在后台運行時效果很好。 但是,當應用程序關閉/未運行時,當用戶在通知中點擊“啟動”時,應用程序將啟動主屏幕,然后返回主屏幕。
我在這里嘗試了許多代碼解決方案,其中大多數涉及以下方面:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (notification) {
// handle your notification here.
}
}
但是無論我把它放在哪里,該應用程序都會啟動,但現在變成黑色。
這是我的代碼,有人可以幫我弄清楚在這里做什么嗎? 請不要,我正在使用Dreamweaver / phonegap來構建應用程序。

對於本地通知,您需要在中添加以下內容:
- (void)applicationDidFinishLaunchingWithOptions:(UIApplication *)application
{
UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
}
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
}
事實證明...
我不確定為什么會崩潰,但是如果其他任何人遇到此問題,則通知將在您的構建版本發布時啟動該應用程序。。。調試或其他狀態。
因此,當您運行時,請運行RELEASE,它應該可以正常工作!
