ios - Scale UIView using UISlider -

i'm trying scale uiview using uislider result not approach:

- (void)setscale:(float)scale {    cgaffinetransform transform = cgaffinetransformscale(myview.transform, scale, scale);             myview.transform = transform;  } 

thanks

you want change scale based on identity transform (which represents object without changes). code works:

- (void)sliderdidchangevalue:(id)sender {     // slider     uislider *slider = sender;      // view or use ivar if have in 1     uiview *view = [self.view viewwithtag:12];      cgaffinetransform transform = cgaffinetransformscale(cgaffinetransformidentity, slider.value, slider.value);     view.transform = transform; } 

when create slider may want start value @ 1 if view starting @ full size.
