iphone - Rotation to a specific angle not working -


i have image of cartoon face rotate shaking head little bit left right (as when hearing music) specific duration of time 5-7 seconds. so, doing following:

-(void)rotation{  cabasicanimation *rotate = [cabasicanimation animationwithkeypath:@"transform.rotation.z"]; [rotate setfromvalue:[nsnumber numberwithfloat:0.0]]; [rotate settovalue:[nsnumber numberwithfloat:45]]; [rotate setduration:5.0]; [rotate setautoreverses:yes]; [rotate settimingfunction:[camediatimingfunction functionwithname: kcamediatimingfunctioneaseineaseout]];  [[faceimage layer] addanimation:rotate forkey:@"danglefaceimage"];  }

but image spinning ball! think code not correct @ all. how can rotation?

you have work on setting anchor point of layer. place anchor point of layer containing face @ lower mid bottom. rotation take place point. appear head tilting neck.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
