Is It Possible to NSLog C Structs Like CGRect or CGPoint

Question

I want to be able to debug C structures without having to explicitly type every property that they consist of   i e  I want to be able to do something like this   CGPoint cgPoint   CGPointMake 0 0   NSLog       cgPoint     Obviously the      won t work  hence the question

Yes  you can use bellow few functions like  First you have to convert CGPoint struct into string  see example  1  NSStringFromCGPoint    2  NSStringFromCGSize    3  NSStringFromCGRect    4  NSStringFromCGAffineTransform    5  NSStringFromUIEdgeInsets    For example   1  NSLog   NSStringFromCGPoint        NSStringFromCGRect cgPointValue      Like this

Since Stack Overflow   s broken RSS just resurrected this question for me  here   s my almost-general solution  JAValueToString  This lets you write JA DUMP cgPoint  and get cgPoint    0  0  logged

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

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

You can use NSValue for this  An NSValue object is a simple container for a single C or Objective-C data item  It can hold any of the scalar types such as int  float  and char  as well as pointers  structures  and object ids   Example        CGPoint cgPoint   CGPointMake 10 30       NSLog        NSValue valueWithCGPoint cgPoint      OUTPUT   NSPoint   10  30    Hope it helps you
