ios - How to rotate UIImageview anticlock wise -


I am using the following code for the full rotate image for the clock clock 

 < code> - (zero) runSpinAnimationOnView: (UIView *) Viewing Period: (CGFLoAet) Duration Rotation: (CGFLoate) Repeat: (Float) Repeat; {CABasicAnimation * RotationAnimation; Rotation animation = [with CABasic animation animation: @ "transform. Rotation.z"]; Rotation animation.Tavaluos = [NSNumber Number: Flowmet: Rotation * 2.0 / * Full Rotation * / * Rotation * Period]; Rotation animation Period = period; Rotation animation resolution = yes; Rotation animation.repeatcode = repeat; [view.layer addAnimation: rotation for animation: @ "rotation animation"]; }   
 and is calling it  
  [manually run animation animationview: _ cycle image duration: 0.1 rotation: repeat MOPI: 13];   
 This image rotates in the direction of clockwise and puts good locks, but can rotate the same image and the same animation and duration clockwise. Please help   
 
 
 For an anti-clockwise rotation,  rotationAnimation.toValue  Set a  negative  value, for example  
  rotationAnimation.toValue = @ (- 2.0 * M_PI); For a complete anti-clockwise rotation

The circuit has the following specifications: The present value of swift SW15-0 on the D2 board should be shown in four hexadecimal four sections of HEX3-0. This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
