还是不对,App有自主唤醒的能力的,只是条件被限制的很死。最好的例子,以前的Dropbox能通过滥用定位服务来实现不定期唤醒,在后台上传照片(这么做是因为iOS上唤醒条件实在是少的可怜)(iOS9好像不需要了)
https://www.dropbox.com/en/help/209
Here's how it works: Normally, photos and videos can upload while the Dropbox app is open and for only a few minutes after it is closed. But with background uploading turned on, the app will automatically resume unfinished uploads when it detects a significant change in your device's location. This feature is designed to make your Camera Upload feature work more efficiently and does not collect your location information.
无论在哪个定义里,iOS都是个多任务系统,部分程序如Safari/音乐是享受着能一直呆在后台的待遇的。(但是内存不够了Safari仍然会要重载)
主要问题还是Apple动作太慢了,API不够。
