Recently, I worked on a class derived from UIScrollView. In order to dump the CGRect's conveniently, I mean better than NSStringFromCGRect(), I introduced the following macro:
#ifdef DEBUG
#define DBG(format, ...) NSLog(@"%d,%s,"format,__LINE__,__FUNCTION__,##__VA_ARGS__);
#define DUMP_RECT(rect) DBG("\n" \
#rect"\n" \
"....x:|%.0f|\n" \
"....y:|%.0f|\n" \
"....width:|%.0f|\n" \
"....height:|%.0f|\n", \
rect.origin.x, \
rect.origin.y, \
rect.size.width, \
rect.size.height)
#else
#define DBG(format, ...)
#define DUMP_RECT(rect)
#endif
Note the stringizing operator (#) operator to dump the "rect". Its sample use in LPTSCrollView class:
- (void)reset
{
...
DUMP_RECT(self.frame)
DUMP_RECT(self.bounds)
...
}
Its sample outputs:
2014-08-29 16:15:03.829 PhotonPro[18253:60b] 98,-[LPTScrollView reset],
self.frame
....x:|0|
....y:|0|
....width:|320|
....height:|568|
2014-08-29 16:15:03.830 PhotonPro[18253:60b] 100,-[LPTScrollView reset],
self.bounds
....x:|0|
....y:|0|
....width:|320|
....height:|568|
Hopefully, it will help somebody!
