IOS仅在发布时崩溃

Question

我遇到了无法重现的崩溃，我真的不明白崩溃日志。我终于设法象征着崩溃日志，所以它应该有点用处。我只在构建发布时存档错误（存档并上传到hockeyapp）。谁能指出我正确的方向？我的Objective-c和iOS知识有点缺乏：

是的，我可以做一个发布版本但仍在调试吗？因为我在两个不同的物理设备以及任何模拟器上调试时都不会出现此错误。

Answer 1

Debug builds have no optimisation enabled (-O0), whereas release builds have optimisation enabled (-O3 or -Os). You can just go into the build settings on Xcode in the Debug configuration and temporarily turn up the optimisation level - this will keep all the other debug goodies (symbols etc) but hopefully also flush out the release mode bug.

also, you can set release mode:

1.Go to "Project" command in an Xcode application menu and chose "Edit Scheme"(Shortcut: ⌘< )

2.Select "Run Project name" in left pane

3.In right pane, under "Info" tab change "Build Configuration" to "Release"
