Is It Possible to NSLog C Structs (Like CGRect or CGPoint)?

You can try this:

NSLog(@"%@", NSStringFromCGPoint(cgPoint));

There are a number of functions provided by UIKit that convert the various CG structs into NSStrings. The reason it doesn't work is because %@ signifies an object. A CGPoint is a C struct (and so are CGRects and CGSizes).

NSLog(@"%@", CGRectCreateDictionaryRepresentation(rect));

There are a few functions like:

NSStringFromCGPoint  
NSStringFromCGSize  
NSStringFromCGRect  
NSStringFromCGAffineTransform  
NSStringFromUIEdgeInsets

An example:

NSLog(@"rect1: %@", NSStringFromCGRect(rect1));

I use the following macro to help me out with NSRect:

#define LogRect(RECT) NSLog(@"%s: (%0.0f, %0.0f) %0.0f x %0.0f",
    #RECT, RECT.origin.x, RECT.origin.y, RECT.size.width, RECT.size.height)

You could do something similar for CGPoint:

@define LogCGPoint(POINT) NSLog(@"%s: (%0.0f, %0.0f)",
    #POINT POINT.x, POINT.y);

Using it as follows:

LogCGPoint(cgPoint);

Would produce the following:

cgPoint: (100, 200)
