xCode编程教学两点之间距离的计算

iOSSDK-xCode编程教学:两点之间距离的计算计算两个object中点之间距离的计算,例如：两个UIImageView;-(void)loadView{[superloadView];//创建一个图像对象01UIImageView*imageView01=[[[UIImageViewalloc]initWithFrame:CGRectMake(200,200,60,60)]autorelease];//创建一个图像对象02UIImageView*imageView02=[[[UIImageViewalloc]initWithFrame:CGRectMake(200,300,60,60)]autorelease];//建立一个浮点函数floatdistance;//使用本章内容的程式计算两个object的距离distance=[selfdistanceFromPointX:imageView01.centerdistanceToPointY:imageView02.center];NSLog(@Distanceis%f,distance);}-(float)distanceFromPointX:(CGPoint)startdistanceToPointY:(CGPoint)end{floatdistance;//下面就是高中的数学，不详细解释了CGFloatxDist=(end.x-start.x);CGFloatyDist=(end.y-start.y);distance=sqrt((xDist*xDist)+(yDist*yDist));returndistance;}
