我们如何获得的UIImageView坐标编程方式？ [英] How do we get the coordinates of an UIImageView programmatically?

问题描述

我想获得的UIImageView坐标编程。我该怎么做呢？

I would like to get the coordinates of an UIImageView programmatically. How do I do this?

例如我有一个正方形。我想获得的所有角落的坐标。我该怎么继续？

For example I have a square. I want to get the coordinates of all the corners. How must i proceed?

NSLog("%f", ImageView.frame.origin.x);
NSLog("%f", ImageView.frame.origin.y);

我得到广场的左上坐标。

I get the topleft coordinate of the square.

我必须说，广场（ImageView的）转动，这就是为什么我一定要得到它的坐标。

I must say that the square (imageview) rotates and that's why I must get it's coordinates.

推荐答案

在其坐标坐标空间？

每个UIView的具有其自己的坐标空间。您可以通过请求其边界。

Each UIView has its own coordinate space. You can refer to a view's size in its own coordinate space by asking for its bounds.

一个视图在其父视图的大小和位置被称为其架。在你的榜样，你要求其父图像视图的左上角视图的坐标空间。

A view's size and position in its parent view is called its frame. In your example, you're asking for the image view's top left corner in its parent view's coordinate space.

如果这就是你想要做什么，然后尝试这些：

If that's what you want to do, then try these:

frame.origin.x
frame.origin.y
frame.size.width
frame.size.height

通过添加这些一起，你可以得到任何坐标：例如，在X的右上方协调会

By adding those together you can get any coordinate: for example, the x coordinate of the top right would be

frame.origin.x + frame.size.width
