ios - CAAnimationGroup with CAKeyframeAnimation and CABasicAnimation -


i'm trying animate view along curved path , scale down @ same time:

cakeyframeanimation *pathanimation = [cakeyframeanimation animationwithkeypath:@"position"];     pathanimation.calculationmode = kcaanimationpaced;     pathanimation.fillmode = kcafillmodeforwards;     pathanimation.removedoncompletion = no;     //setting endpoint of animation     cgpoint endpoint = endcenter;     cgmutablepathref curvedpath = cgpathcreatemutable();     cgpathmovetopoint(curvedpath, null, vieworigin.x, vieworigin.y);     cgpathaddcurvetopoint(curvedpath, null, vieworigin.x+200, vieworigin.y-150, endpoint.x+100, endpoint.y+10, endpoint.x, endpoint.y);     pathanimation.path = curvedpath;     cgpathrelease(curvedpath);      // set scaling     cabasicanimation *resizeanimation = [cabasicanimation animationwithkeypath:@"transform.scale"];     resizeanimation.tovalue = [nsnumber numberwithdouble:0.4];     resizeanimation.fillmode = kcafillmodeforwards;     resizeanimation.removedoncompletion = no;      caanimationgroup *group = [caanimationgroup animation];     group.fillmode = kcafillmodeforwards;     group.removedoncompletion = yes; [group setanimations:[nsarray arraywithobjects: pathanimation, resizeanimation, nil]];     group.duration = 3.7f;     group.delegate = self;     [group setvalue:self.myview forkey:@"imageviewbeinganimated"];  self.myview.center = endcenter; self.myview.transform = self.myviewtransform; [self.myview.layer addanimation:group forkey:@"savinganimation"];

the problem instead of view scaling down gradually moves, gets scaled down, moves along path. need to scale down moves obviously.

solved doing this:

resizeanimation.fromvalue = [nsnumber numberwithdouble:1.0];

i don't understand why have this. seems should start default fromvalue of current transform.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
