ios - NSAttributedString drawInRect disappears when the frame is offset -


i have strange problem. when offset frame/rect use draw nsattributedstring

my text disappears. ideas why? here image simple offset of 40 px.

r.size = [self.text boundingrectwithsize:r.size                                      options:nsstringdrawinguseslinefragmentorigin                                      context:nil].size;     r.origin.y +=40;     [[uicolor orangecolor] setfill];     cgcontextfillrect(ctx, r);     [self.text drawinrect:r];

result:

enter image description here

and here without offset. enter image description here

how draw attributedtext @ given offset?

i don't know why question has not yet been addressed. serious issue nsattributedstring api hope apple acknowledges soon, either in documentation or patching implementation.

for time being, can work around issue translating graphics context before drawing string.

cgcontextref context = whatever; cgcontextsavegstate(context); cgcontexttranslatectm(context, x, y); // draw here cgcontextrestoregstate(context);

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
