ios - iPhone - UIImageView moves when Rotate Animation > 90 degree -


I am using this code to rotate my image 

  - ( IBAction) Spin: (ID) sender {[UIView startAnimations: zero reference: zero]; [UIView Set Animation Duration: 5.0]; [UIView Set AnimationBuginFrenchTant: Yes]; self.imgRad.transform = CGAffineTransformMakeRotation (arc4random ()% 360 * M_PI / 180); [UIView commitAnimations]; }   
 Now I have two problems.  
  First:  If the random number is greater than 90, then the image rotates near its center in the right corner and in relation to its random number. So much more number = the position of the image is close to the right corner. How can I fix that? Do I have to set my new  UIImageView  every time more than 90?  
  Second:  If the number is for example 300, then the image does not rotate 300 degrees, it spins only 60 degrees on the other side. How can I fix this problem?  
 Thank you very much!  
 
 
     
  •  The first problem may be due to an incorrect signal point when using the transformer  CAAnimation .  
  •  The second problem can be solved by using  NSNumber .   
     Code:    CABasicAnimation * rotation = [with CABasic Animation Animation: @ "Transformation.Rotation"]; Rotation.fromValue = [Flow with NSNumber Number: 0]; Rotation.toValue = [with NSN number number Flat: (ARC4RRM (~% 360 * M_PI / 180)] rotation.duration = 5.0f; rotation.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseInEaseOut]; Rotation.fillMode = kCAFillModeForwards; Rotation. removedOncompletion = no; [self. imgRad.layer addAnimation: for rotation forkey: @ "rotatationRandom"];

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
