UIImage+FloodFill.m:423

Or may be memory issue,
App is crashing when trying to multiple fill.
Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)

Seems this is the same issue

Does anybody fix this?

Hi Chintan Dave,
Seems we can fix this issue by adding thread on setting image,
And now I am getting thread issue on 71 row
CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
Also getting thread issue, trying to fix with async thread on main thread, but no results.

Can you please help me fix this?

Can you provide me image for which you are getting this issue?

[goharika]

I am trying to draw something like this, and when filling this boxes.
And in image above you can see the message error.

[Chintan-Dave]

I tried playing with that image is working ok for me.

Can you give more specific detail so that we can reproduce it?

[goharika]

It doesn't happen always.
Sometimes when I doing much fills, that brings me this issue
Crashed: com.apple.main-thread
0 0x102a76838 -[UIImage(FloodFill) floodFillFromPoint:withColor:andTolerance:useAntiAlias:] (UIImage+FloodFill.m:423)
1 0x102a75044 -[UIImage(FloodFill) floodFillFromPoint:withColor:andTolerance:] (UIImage+FloodFill.m:28)

I have tried to fix this by add set image part in thread, and give for him a time. See in screenshot
But that gives me some time, and after again the same.
