UIImage vs NSImage: Drawing to an off screen image in iOS

Question

In mac osx (cocoa), It is very easy to make a blank image of a specific size and draw to it off screen:

NSImage* image = [[NSImage alloc] initWithSize:NSMakeSi         


        

Answer 1

Something like this:

UIGraphicsBeginImageContextWithOptions(mySize, NO, 0.0f);       
CGContextRef context = UIGraphicsGetCurrentContext();
UIGraphicsPushContext(context);

[myImage drawInRect:myImageRect];
[myText drawAtPoint:myOrigin withFont:myFont];

UIGraphicsPopContext();
UIImage *myNewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
