intwidth=rect.width();// 获取矩形的宽度intheight=rect.height();// 获取矩形的高度 1. 2. 判断两个矩形是否相交 我们可以使用Rect类的intersect()方法来判断两个矩形是否相交。如果两个矩形相交,那么intersect()方法会返回true,并且会修改当前矩形的坐标,使其变为两个矩形的交集。例如: Rectrect1=newRect(0...

首先,我们需要创建一个Rect对象,可以使用new Rect()来实现。以下是创建一个Rect对象的代码: Rectrect=newRect(); 1. 这段代码将创建一个名为rect的Rect对象。 2. 设置矩形的坐标和大小 接下来,我们需要设置矩形的坐标和大小。Rect类提供了几种方法来设置矩形的位置和大小。以下是设置矩形坐标和大小的代码: rect...
10. CGRect与NSValue转换 在NSArray,NSDictionary容器中只能存储Objetive-C对象,不能直接存储C结构体,所有需要存储矩形时,需要将其转换为NSValue值。 CGRect rect = CGRectMake(0,0,100,200); NSValue*value =[NSValue valueWithCGRect:rect]; CGRect newRect= [value CGRectValue];...
Rect parallels a convention that is supported by a type converter, such that properties that take a Rect as their value can specify a Rect as a formatted string. The type converter generates a new Rect value based on processing the string. The type converter functions both for XAML uses and...
