Title
Body
I'd like to create a UIImage object from the current graphics context. More specifically, my use case is a view that the user can draw lines on. They may draw incrementally. After they are done, I'd like to create a UIImage to represent their drawing. Here is what drawRect: looks like for me now: - (void)drawRect:(CGRect)rect { CGContextRef c = UIGraphicsGetCurrentContext(); CGContextSaveGState(c); CGContextSetStrokeColorWithColor(c, [UIColor blackColor].CGColor); CGContextSetLineWidth(c,1.5f); for(CFIndex i = 0; i < CFArrayGetCount(_pathArray); i++) { CGPathRef path = CFArrayGetValueAtIndex(_pathArray, i); CGContextAddPath(c, path); } CGContextStrokePath(c); CGContextRestoreGState(c); } ... where _pathArray is of type CFArrayRef, and is populated every time touchesEnded: is invoked. Also note that drawRect: may be invoked several times, as the user draws. When the user is done, I'd like to create a UIImage object that represents the graphics context. Any suggestions on how to do this?
