Re: [jira] [Created] (WEEX-19) Weex(iOS)，If want to let the frame adjust content's height, you need set frame(0, 0, width, NAN), but it sometime will crash

[Adam Feng]

Setting instance’s frame to NAN can adjust content’s height by layout,  and I 
have tried in playground, it’s ok and did not crash.  So maybe it’s relevant to 
your native environment,  I need more information about the crash(e.g. the 
crash log, the init code.)

Thanks.
