* To compile for ip5(armv7 (cputype (12) cpusubtype (11)), should set "Build Active Architecture Only" to No. As default the debug mode is set to YES and compile for current device. But be care the build for armv7s will make the lib or app about 1 time larger that before.
* Combin i386 and arm into universal version won't make the target app larger. fo it only get the target architecture binary.
