How add entitlement "com.apple.springboard.launchapplications" for jailbreak iPhone [duplicate] - ios

Question

I have some problems.
I want use in my app next function:
int SBSLaunchApplicationWithIdentifier(CFStringRef displayIdentifier, Boolean suspended);
I add SpringboardServices.framework in my project
I add URL Schemes for my app
Created the file entitlement.xml with
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.springboard.launchapplications</key>
<true/>
</dict>
</plist>
Paste entitlement.xml in `Developer/Xcode/DerivedData/MyApp-efjwoxgwdyixnfassijmwtptxvlj/Build/Products/Debug-iphoneos/
Paste ldid in Developer/Xcode/DerivedData/MyApp-efjwoxgwdyixnfassijmwtptxvlj/Build/Products/Debug-iphoneos/
Did ./ldid -Sentitlement.xml MyApp.app/MyApp in console.
It's good working
But I saw some problem:
I did ./ldid -e MyApp.app/MyApp and saw next in console(double output entitlement.xml):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "apple.com/DTDs/PropertyList-1.0.dtd">;
<plist version="1.0">
<dict>
<key>com.apple.springboard.launchapplications</key>
<true/>
</dict>
</plist>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "apple.com/DTDs/PropertyList-1.0.dtd">;
<plist version="1.0">
<dict>
<key>com.apple.springboard.launchapplications</key>
<true/>
</dict>
</plist>
I create MyApp.ipa file consist with:
ItunesArtwork
Payload
|---MyApp.app
|---Info.plist
I installed this ipa file on my jailbreak iPhone via iTools
MyApp is run but can't do some function. I try authorization via Internet and it's false. But when I installed app without added entitlement an didn't do some instruction with ldid, application working fine.
P.S: i didn't set in true Targets->AppName->Summary->Entitlements property (is it true or false ?)
Please help me
