i'm "attempting" to add a stroke to a rect, and i realized that
NSBezierPath is not available on iPhone SDK, so i'm forced to subclass
the rect...
my StrokeView:UIView class.m is this:
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
frame = CGRectMake(10, 10, 100, 100);
}
return self;
}
- (void)drawRect:(CGRect)rect
{
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(context, 2.0);
CGContextSetStrokeColorWithColor(context, [UIColor whiteColor].CGColor);
CGContextStrokePath(context);
}
now in my may app controller.h i have the following:
@class StrokeView;
@interface AppController : UIViewController
{
StrokeView *strokeViewClass;
}
@property (nonatomic, retain) StrokeView *strokeViewClass;
and in the implementation file, i'm calling for the class to be added
as a subview with this:
#import "StrokeView.h"
[self.view insertSubview:strokeViewClass atIndex:1];
totally doesn't work.
