Simple way to change the position of UIView

Question

I change the position of a UIView with following codes without changing size of the view   CGRect f   aView frame  f origin x   100     new x f origin y   200     new y aView frame   f    Is there more simple way to change only the view position

I found a similar approach  it uses a category as well  with gcamp s answer that helped me greatly here  In your case is as simple as this   aView topLeft   CGPointMake 100  200     but if you want for example to centre horizontal and to the left with another view you can simply   aView topLeft   anotherView middleLeft

Other way   CGPoint position   CGPointMake 100 30    self setFrame  CGRect          origin   position         size   self frame size       This i save size parameters and change origin only

aView center   CGPointMake 150  150      set center   or  aView frame   CGRectMake  100  200  aView frame size width  aView frame size height       set new position exactly   or  aView frame   CGRectOffset  aView frame  10  10       offset by an amount   Edit   I didn t compile this yet  but it should work    define CGRectSetPos  r  x  y   CGRectMake  x  y  r size width  r size height    aView frame   CGRectSetPos  aView frame  100  200

UIView s also have a center property  If you just want to move the position rather than resize  you can just change that - eg   aView center   CGPointMake 50  200    Otherwise you would do it the way you posted

In my work we not use macros  So the solution provide by  TomSwift inspired to me  I see the implementation for CGRectMake and create the same CGRectSetPos but without macros   CG INLINE CGRect CGRectSetPos CGRect frame  CGFloat x  CGFloat y      CGRect rect    rect origin x   x  rect origin y   y    rect size width   frame size width  rect size height   frame size height    return rect      To use I only put frame  X and Y  viewcontroller view frame   CGRectSetPos viewcontroller view frame  100  100     Work for me

I had the same problem  I made a simple UIView category that fixes that    h   import  lt UIKit UIKit h gt     interface UIView  GCLibrary    property  nonatomic  assign  CGFloat height   property  nonatomic  assign  CGFloat width   property  nonatomic  assign  CGFloat x   property  nonatomic  assign  CGFloat y    end    m    import  UIView GCLibrary h     implementation UIView  GCLibrary   -  CGFloat  height       return self frame size height     -  CGFloat  width       return self frame size width     -  CGFloat  x       return self frame origin x     -  CGFloat  y       return self frame origin y     -  CGFloat  centerY       return self center y     -  CGFloat  centerX       return self center x     -  void  setHeight  CGFloat  newHeight       CGRect frame   self frame      frame size height   newHeight      self frame   frame     -  void  setWidth  CGFloat  newWidth       CGRect frame   self frame      frame size width   newWidth      self frame   frame     -  void  setX  CGFloat  newX       CGRect frame   self frame      frame origin x   newX      self frame   frame     -  void  setY  CGFloat  newY       CGRect frame   self frame      frame origin y   newY      self frame   frame      end

CGRectOffset has since been replaced with the instance method offsetBy    https   developer apple com reference coregraphics cgrect 1454841-offsetby  For example  what used to be  aView frame   CGRectOffset aView frame  10  10    would now be  aView frame   aView frame offsetBy dx  CGFloat 10   dy  CGFloat 10
