CGAffineTransform 仿射轉移
1宣告陣列
2套用要轉換的參數

CGAffineTransform tf=CGAffineTransformIdentity; tf=CGAffineTransformTranslate(tf, img_x,img_y);//平移 tf=CGAffineTransformRotate(tf, radian);//旋轉 tf=CGAffineTransformScale(tf, 1.0f, 1.0f);//縮放 [imageView setTransform:tf];//將view套用整個轉移 [imageView setNeedsDisplay];//重畫畫面
