objective c - How do I change my iOS applications' entitlements? -

i need run next code turn off iphone screen .

on ios6:

void (*bksdisplayservicessetscreenblanked)(bool blanked) = (void (*)(bool blanked))dlsym(rtld_default, "bksdisplayservicessetscreenblanked");

and use:

bksdisplayservicessetscreenblanked(1); // 1 dim, 0 undim

it doesnt work. told me need com.apple.backboard.client entitlements work on iphone. dont know how set these entitlements. have seen several ways set entitlements confusing me, one.

yes, need code sign entitlements. but, no, doesn't have apple certificate on jailbroken phones. can false code sign, downloading ldid executable, , doing

cd myappname.app ldid -sentitlements.xml myappname

assuming app named myappname , made entitlements file entitlements.xml. believe entitlements file work you, if false code-signed ldid.

class="lang-xml prettyprint-override"><!doctype plist public "-//apple//dtd plist 1.0//en" "http://www.apple.com/dtds/propertylist-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.backboard.client</key> <true/> </dict> </plist>

even above method, place above entitlements file?

for jailbreak app/entitlement, need this. first, create file named entitlements.xml (or whatever like):

class="lang-xml prettyprint-override"><!doctype plist public "-//apple//dtd plist 1.0//en" "http://www.apple.com/dtds/propertylist-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.backboard.client</key> <true/> </dict> </plist>

you can add together more entitlements if need. illustration file grants app com.apple.backboard.client entitlement.

it doesn't matter where set file. key is:

you need modify xcode's sdksettings.plist file, as shown here. code_signing_required should set no. do not code sign app in xcode. in build settings, create sure code sign identity set don't code sign. after build app ios device (not simulator!), go directory on mac output files located. app named helloworld, you're looking helloworld.app folder. can differ depending on configuration, won't bother trying tell is. if in doubt, utilize command line find command. download ldid pre-built this location, or source here. copy entitlements.xml file same directory helloworld.app is. (note: don't have have here ... if set somewhere else, adjust command line show below). change directory directory entitlements.xml file is. fake code-sign command: class="lang-sh prettyprint-override">$ldid -sentitlements.xml helloworld.app/helloworld

after point, you'll need transfer entire helloworld.app folder install app on device. there's many ways that, , sounds have way.

i have whole process setup script, create easier.

note: not stating whether or not entitlement right entitlement utilize bksdisplayservicessetscreenblanked() phone call on ios 6. haven't tested that. know entitlement works allow utilize sbdimscreen() on lower ios versions. but, reply description of how add together kind of entitlement jailbreak app.
