Some basic animation effects of a layer

#define Kradiantodegrees (Radian) (Radian * 180.0)/(M_PI)

• Flashing

[Self.testView.layer addanimation:[self opacityforever_animation:0.5] forkey:nil];

• Mobile

[Self.testView.layer addanimation:[self Duration:3 move:[nsnumber numberwithinteger:200]] forkey:nil];

• Zoom

[Self.testView.layer addanimation:[self scale:[nsnumber numberwithinteger:1] Orgin:[nsnumber Numberwithinteger:3] Durtimes:1 Rep:maxfloat] Forkey:nil];

• Combination

Nsarray *myarray = [Nsarray arraywithobjects:[self opacityforever_animation:0.5], [self duration:1.0f move:[NSNumber NUMBERWITHFLOAT:200.0F]], [self scale:[nsnumber numberwithfloat:1.0f] Orgin:[nsnumber numberwithfloat:3.0f] DurTimes : 2.0f Rep:maxfloat], nil];

[Self.testView.layer addanimation:[self groupanimation:myarray durtimes:3.0f rep:maxfloat] forkey:nil];

• Path

Cgmutablepathref Mypah = cgpathcreatemutable ();

Cgpathmovetopoint (Mypah, nil,30, 77);

Cgpathaddcurvetopoint (Mypah, Nil, 50, 50, 60, 200, 200, 200);//Here is the control point.

[Self.testView.layer addanimation:[self keyframeanimation:mypah durtimes:5 rep:maxfloat] forkey:nil];

• Rotation

[Self.testView.layer addanimation:[self Rotation:2 degree:kradiantodegrees (All) Direction:1 Repeatcount:maxfloat] Forkey:nil];

• Removed from

[Self.testView.layer removeallanimations];
