Something like this should work for you:

<pre><code>NSView* myView; // The view you are converting coordinates to
NSPoint globalLocation = [ NSEvent mouseLocation ];
NSPoint windowLocation = [ [ myView window ] convertScreenToBase: globalLocation ];
NSPoint viewLocation = [ myView convertPoint: windowLocation fromView: nil ];
if( NSPointInRect( viewLocation, [ myView bounds ] ) ) {
 // Do your thing here
}
</code></pre>

I don't personally use this many local variables but hopefully this make this example clearer.

Use NSView's convertPoint:fromView: method with fromView as nil to covert a point in window coordinates to a view's coordinate system.

After converting the mouse point to the view's coordinate system, I would use NSView's mouse:inRect: method instead of NSPointInRect as the former also accounts for flipped coordinate systems.

Alternatively, you could use a <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/EventOverview/TrackingAreaObjects/TrackingAreaObjects.html" rel="noreferrer">Tracking Area Object</a>.

Some code making use of mouse:inRect: (the recommended way; that accounts for flipped coordinates)

<pre><code>CGPoint point = [self convertPoint:[event locationInWindow] fromView:nil];
CGRect rect = [self bounds];
if ([self mouse:point inRect:rect]) {
}

None of these answers take into account that a view might not be rectangular. 

Here is an universal method that works on non-rectangular views as well. Think watch-face or a complex path shape.

This code snippet will give you a localPoint from a globalPoint (aka globalToLocal). (GlobalPoint in 0,0 window space) If you change the argument to "toView" then you get a "localToGlobal" point. 

<pre><code>let localPoint = convertPoint(aPoint, fromView: self.window?.contentView) 
</code></pre>

The bellow code would return true or false if the point was inside the path or not. 

<code>CGPathContainsPoint(someCGPath,nil,localPoint,true)</code>

NOTE:
aPoint is a globalPoint derived from the parameter in hitTest, it can also be derived from:

<pre><code>(self.window?.mouseLocationOutsideOfEventStream)!
</code></pre>

NOTE: 
There might be a more correct way of doing this. But this works,and doesn't care about flipped views.

blocks|key|539605|text|NSView+isMousePoint函数适用于我，而不必担心任何CG。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|539606|func+isMouseInView(view:+NSView)+->+Bool?+{

The NSView <a href="https://developer.apple.com/documentation/appkit/nsview/1483237-ismousepoint" rel="noreferrer">isMousePoint</a> function works for me, without having to worry about anything CG.

<pre><code>func isMouseInView(view: NSView) -&gt; Bool? {
 if let window = view.window {
 return view.isMousePoint(window.mouseLocationOutsideOfEventStream, in: view.frame)
 }
 return nil
}
</code></pre>

I need to find if the mouse position is inside an NSView's rect.

I'd use <code>NSPointInRect(point, rect)</code>, but I'd need to convert the rect coordinates to screen coordinates and I'm not sure how. Any help would be much appreciated!

我需要找出鼠标位置是否在NSView的矩形内。我会使用NSPointInRect(point, rect)，但我需要将矩形坐标转换为屏幕坐标，并且我不确定如何转换。任何帮助都将不胜感激！
