hi,
i got a very basic question on iphone development. so i add an uiview via IB
and try to update it by making my own interface called updateInterface(). in
the update interface i put this code:
CGRect frame = [polyView frame];
NSArray*polypath = [[selfclass]pointsForPolygonInRect:frame
numberOfSides:[myPolynumberOfSides]];
CGContextRefmyContext = UIGraphicsGetCurrentContext();
int i = 0;
CGContextSetRGBStrokeColor(myContext, 0, 0, 1, 1);
for (NSValue* value in polypath) {
CGPoint point = [value CGPointValue];
if (i == 0) {
CGContextMoveToPoint(myContext, point.x, point.y);
i++;
}
else {
CGContextAddLineToPoint(myContext, point.x, point.y);
}
}
CGContextClosePath(myContext);
im trying to draw a polygon here built by lines from one point to antoher. the
"pointsForPolygonInRect" is working properly but my UIview(polyView) isnt
showing anything. i dont really understand what happened up there, i just
googled it around working for a proper method. im very new to cocoa-dev so
please do a more human language ;)
thank you
