little more help with a CATiledLayer
- by Brodie4598
Okay so I am trying to adapt an online tutorial for CATiledLayer to use in my app. The example uses a PDF but I need to display a JPG.
I'm getting close, but I just cant figure this out. Should I be using a UIImage or something else?
#import <QuartzCore/QuartzCore.h>
#import "practiceViewController.h"
@implementation practiceViewController
- (void)viewDidLoad
{
[super viewDidLoad];
NSBundle *bundle = [[NSBundle mainBundle]autorelease];
NSString *path = [bundle pathForResource:@"H-5" ofType:@"jpg"];
NSData *data = [NSData dataWithContentsOfFile:path];
image = [UIImage imageWithData:data];
CGRect pageRect = CGRectMake(0, 0, 1600, 2400);
CATiledLayer *tiledLayer = [CATiledLayer layer];
tiledLayer.delegate = self;
tiledLayer.tileSize = CGSizeMake(1024.0, 1024.0);
tiledLayer.levelsOfDetail = 1000;
tiledLayer.levelsOfDetailBias = 1000;
tiledLayer.frame = pageRect;
myContentView = [[UIView alloc] initWithFrame:pageRect];
[myContentView.layer addSublayer:tiledLayer];
CGRect viewFrame = self.view.frame;
viewFrame.origin = CGPointZero;
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:viewFrame];
scrollView.delegate = self;
scrollView.contentSize = pageRect.size;
scrollView.maximumZoomScale = 1000;
[scrollView addSubview:myContentView];
[self.view addSubview:scrollView];
}
- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView
{
return myContentView;
}
- (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx
{
NEED HE:LP WITH THIS
}
@end
