UIScrollView loading an image
- by treasure
i must say i m not very good at this. and you probably know that (cause noone bothers to answer my questions) but i will keep on trying!!!
lol
here it goes!
i wanted to find an "easy" way to use the pinch/zoom function on my app!
so i decided to use a UIScrollView.
so far so good.
i load my image from an sqlite db like so:
- (void)loadView {
self.title = @"ScrollView";
imageView = [[UIImageView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
imageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.backgroundColor = [UIColor blackColor];
self.view = imageView;}
and
- (void)viewWillAppear:(BOOL)animated {imageView.image = entity.imageA}
I followed a tutorial but i cnnot seem to be able to load my image at all:
- (void)vieDidLoad {
imageView = [[UIImageView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
imageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.backgroundColor = [UIColor blackColor];
//when i have this it does load the image but when i cant load my own data!!
/*UIImageView *tempImageView = [[UIImageView alloc] initWithImage:[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://www.austinbull.com/clonemines.png"]]]];
[self setMyImage:tempImageView];
[tempImageView release];*/
myScrollView.contentSize = CGSizeMake(imageView.frame.size.width, imageView.frame.size.height);
myScrollView.maximumZoomScale = 4.0;
myScrollView.minimumZoomScale = 0.75;
myScrollView.clipsToBounds = YES;
myScrollView.delegate = self;
[myScrollView addSubview:imageView];
self.view = scrollView;
[window makeKeyAndVisible];
}
(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
return myImage;
}
any help would be appreciated!
thank you for your time!
