objective c - IOS crash only in release -

-

i have crash can't reproduce , don't understand crashlog. managed symbolize crashlog should bit useful. error when building release (archiving , uploading hockeyapp). can point me in right direction? objective-c , ios knowledge bit lacking:

exception type:  exc_crash (sigabrt) exception codes: 0x0000000000000000, 0x0000000000000000 triggered thread:  0  ___exceptionpreprocess + 122 _objc_exception_throw + 34 +[nsexception raise:format:] + 108 -[uinib instantiatewithowner:options:] + 852 -[nsbundle(uinsbundleadditions) loadnibnamed:owner:options:] + 160 0x43a2e -[uitableview _delegateviewforheaderinsection:] + 36 ___96-[uitableview _sectionheaderview:withframe:forsection:floating:reuseviewifpossible:willdisplay:]_block_invoke + 82 +[uiview(animation) performwithoutanimation:] + 68 -[uitableview _sectionheaderview:withframe:forsection:floating:reuseviewifpossible:willdisplay:] + 542 -[uitableview _sectionheaderviewwithframe:forsection:floating:reuseviewifpossible:willdisplay:] + 58 -[uitableview _updatevisibleheadersandfootersnow:] + 2374 -[uitableview _updatevisiblecellsnow:isrecursive:] + 2864 -[uitableview layoutsubviews] + 182 -[uiview(calayerdelegate) layoutsublayersoflayer:] + 510 -[calayer layoutsublayers] + 132 ca::layer::layout_if_needed(ca::transaction*) + 356 ca::layer::layout_and_display_if_needed(ca::transaction*) + 12 ca::context::commit_transaction(ca::transaction*) + 220 ca::transaction::commit() + 320 __aftercacommithandler + 128 ___cfrunloop_is_calling_out_to_an_observer_callback_function__ + 16 ___cfrunloopdoobservers + 274 ___cfrunlooprun + 910 _cfrunlooprunspecific + 472 _cfrunloopruninmode + 102 _gseventrunmodal + 132 _uiapplicationmain + 1436 0x28082 _tlv_initializer + 2

btw, can release build still debug? since nto error when debugging both on 2 different physical devices of simulator ones.

debug builds have no optimisation enabled (-o0), whereas release builds have optimisation enabled (-o3 or -os). can go build settings on xcode in debug configuration , temporarily turn optimisation level - keep other debug goodies (symbols etc) flush out release mode bug.

also, can set release mode:

1.go "project" command in xcode application menu , chose "edit scheme"(shortcut: ⌘< )

2.select "run project name" in left pane

3.in right pane, under "info" tab change "build configuration" "release"

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
