ios - Swing animation with depth -

in app, have pop banner jumps every time user gets notification server, pop looks sign attached strings top of screen (not code strings lol).

i'm trying achieve swing animation, not side side! , forth, acutely bottom yz point should change, looks popup sign coming towards user, , back, , on....

i hope clear question, matter bugging me long time now.. thanks! !

and again, sorry bad drawing.

this code did far:

// container calayer *container = [calayer layer]; container.frame = cgrectmake(50, 50, 100, 100); [self.view.layer addsublayer:container];   //create plane  calayer *purpleplane = [self addplanetolayer:container                                         size:cgsizemake(100, 100)                                     position:cgpointmake(250, 150)                                        color:[uicolor purplecolor]];    [container addsublayer:imageview.layer];    //apply transform plane  catransform3d t = catransform3didentity;  //add perspective!!!  t.m34 = 1.0/ -100;  //t.m34 = 1.0/ -500;  t = catransform3drotate(t, degtorad(45.0), 0, 1, 0);   purpleplane.transform = t;   catransform3d transform = catransform3didentity; // transform.m34 = 1.0 / -50; container.transform = transform;  cakeyframeanimation *animation = [cakeyframeanimation animationwithkeypath:@"transform"]; animation.values = [nsarray arraywithobjects:                      [nsvalue valuewithcatransform3d:catransform3drotate(transform, 0.8 * m_pi / 2, 100, 100, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, 0 * m_pi / 2, 100, 100, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, -0.6 * m_pi / 2, 100, 1, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, 0 * m_pi / 2, 100, 1, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, 0.3 * m_pi / 2, 100, 1, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, 0 * m_pi / 2, 100, 1, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, -0.1 * m_pi / 2, 100, 1, 0.2)],                     [nsvalue valuewithcatransform3d:catransform3drotate(transform, 0 * m_pi / 2, 100, 1, 0.2)],                        // [nsvalue valuewithcatransform3d:catransform3drotate(transform, 2 * m_pi / 2, 100, 1, 5)],                     //   [nsvalue valuewithcatransform3d:catransform3drotate(transform, 3 * m_pi / 2, 100, 1, 100)],                     //   [nsvalue valuewithcatransform3d:catransform3drotate(transform, 4 * m_pi / 2, 100, 1, 100)],                     nil]; animation.duration = 5; [container addanimation:animation forkey:animation.keypath]; 

as notice, in code, there no effect of view swinging towards you, , that's i'm looking for.

thanks, cheers

sound looking zoom in / out animation, like:

uiview *thestrigviewthing = ...  [uiview animatewithduration: 0.2 delay: 0.0 options: uiviewanimationoptioncurveeasein animations:^{             [thestrigviewthing settransform: cgaffinetransformmakescale(2.0f, 2.0f)];         } completion:^(bool finished) {             [uiview animatewithduration: 0.2 delay: 0.0 options: uiviewanimationoptioncurveeaseout animations:^{                 [thestrigviewthing settransform: cgaffinetransformidentity];             } completion:nil];         }];
