I implemented Push notifications in iOS. I want my application to play a music (about 15sec) when I send a push message. I am currently getting the push message, and the music is being played only if the app is in the foreground. If the app is in the background, it shows up a notification, and when i tap it, it then plays the music.
但是,我如何自动发挥音乐的作用? 我认为,之所以能够做到这一点,是因为在西里,视听镜子可以在背景下运行。 因此,我只想让音乐在观看背景时起作用,并且得到推动。
Can anyone help me with this please?
Thanks, Nithin
Yes, there are two ways to do this.
www.un.org/spanish/ecosoc 传统方式在OS 7之前是登记音频游戏背景模式,并永远保持沉默,这样,在用户杀人之前,你就能够保持自己的背景,或者由于记忆低而死亡。
This way has many drawbacks, the user must launch your app once so that you can start playing the sound and every time the iPhone is shut off, the user need to relaunch your app when he turn on the iPhone.
这也将消耗大量电池。 每天20%-30%
