Hmm... There's no such thing as "subclassing a rect". CGRect is a
structure, not a class.
my StrokeView:UIView class.m is this:
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
frame = CGRectMake(10, 10, 100, 100);
}
return self;
}
You've changed the value of the local variable "frame". If you want
to resize your view you will have to either change the frame before
calling super, or use self.frame = CGRectMake(10, 10, 100, 100) after
self has been initialized.
- (void)drawRect:(CGRect)rect
{
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(context, 2.0);
CGContextSetStrokeColorWithColor(context, [UIColor
whiteColor].CGColor);
CGContextStrokePath(context);
}
You asked for the current path to be stroked, but you haven't told the
context what the current path is. Somewhere in there before the
StrokePath you probably want to do:
CGContextAddRect(context, CGRectMake( <... whatever rect you like
here...>));
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.
Do you ever allocate the strokeView? You've declared that your
UIViewController knows about a stroke view, but you've not actually
created one (at least not with this code example).
It would seem that there is a lot here you don't understand. I would
recommend going back and looking at some basic examples and perhaps
some of the sample code to see if you can learn a bit more.
