类似问题在 iOS 7 的设备崩溃后 App 能正常启动，目前测试发现崩溃后不能正常启动发生在 iOS 9
& & 17:10:31 +08:00
你就不能使用 DSYM 把这个 crash 日志解析出来吗，这谁能看懂！
& & 17:11:32 +08:00
启动超时？看看 AppDelegate 里面的 didFinishLaunch 里面是不是死循环了？
& & 17:31:45 +08:00
@ 仔细看了看是启动时间接近 20s 了，被系统干掉了，估计 iOS 9 的机制，目前还在寻找费时的地方
& & 17:34:16 +08:00
@ 天真了，就是没有奔溃异常被捕捉到，不然就 不会提问，
& & 18:07:37 +08:00
装个 fabric ，捕获比较容易
& & 18:14:39 +08:00
@ 目前是用的友盟统计，没有成功记录崩溃信息，因为项目中混合很多 C++的静态库与代码实现， fabric 有什么特别？

内存吃紧了。
& & 18:48:49 +08:00
& & 19:02:18 +08:00
第三方库装多了吧
& & 02:06:12 +08:00 via iPhone
@ 友盟当然不能和这个专业的比

Exception Note:

应该是是超时被干掉了。
可以用 hopper disassembler 打开你的二进制文件 go to fileo ffset ： 7080236
就可以看到是什么问题了
& & 14:57:21 +08:00
@ 只能是最后一招试试了，正向的问题都需要逆向方案去解决了?
& & 16:16:21 +08:00
此处收楼了，最后比对 commit 发现是 cocoapods pod 'MMPlaceHolder', '~& 1.9',代码中没有使用该库，迷之 BUG 告一段落了
