ios layer 動畫 x y z軸 旋轉

x軸旋**

//第一種
cabasicanimation *theanimation;
theanimation=[cabasicanimation animationwithkeypath:@"transform.rotation.x"];
theanimation.duration=8;
theanimation.removedoncompletion = yes;
theanimation.fromvalue = [nsnumber numberwithfloat:0];
theanimation.tovalue = [nsnumber numberwithfloat:3.1415926];
[yourview.layer addanimation:theanimation forkey:@"animatetransform"];
//第二種
[uiview animatewithduration:1 delay:0 options:uiviewanimationoptioncurveeasein animations:^ completion:^(bool finished) ];

y軸旋**

cabasicanimation *theanimation;
theanimation=[cabasicanimation animationwithkeypath:@"transform.rotation.y"];
theanimation.duration=8;
theanimation.removedoncompletion = yes;
theanimation.fromvalue = [nsnumber numberwithfloat:0];
theanimation.tovalue = [nsnumber numberwithfloat:3.1415926];
[yourview.layer addanimation:theanimation forkey:@"animatetransform"];

z軸旋**

cabasicanimation *theanimation;
theanimation=[cabasicanimation animationwithkeypath:@"transform.rotation.z"];
theanimation.duration=8;
theanimation.removedoncompletion = yes;
theanimation.fromvalue = [nsnumber numberwithfloat:0];
theanimation.tovalue = [nsnumber numberwithfloat:3.1415926];
[yourview.layer addanimation:theanimation forkey:@"animatetransform"];

以上縮放是以view的中心點為中心縮放的，如果需要自定義縮放點，可以設定卯點：

//中心點
[yourview.layer setanchorpoint:cgpointmake(0.5, 0.5)];
//左上角
[yourview.layer setanchorpoint:cgpointmake(0, 0)];
//右下角
[yourview.layer setanchorpoint:cgpointmake(1, 1)];

可設引數

theanimation.repeatcount = 0;
theanimation.autoreverses = no;

旋轉的另一種實現：（以下**繞z軸旋轉180度）

[self.topviewcontroller.view.layer setanchorpoint:cgpointmake(0.5, 0.5)];
[self.topviewcontroller.view.layer settransform:catransform3dmakerotation(0, 0, 0, 1)];
[uiview animatewithduration:8 delay:0.0f options:uiviewanimationoptionallowuserinteraction | uiviewanimationcurveeasein animations:^ completion:^(bool finished) ];
