Question

I have a scrollview of images, I will like to tab them and will pushed to another view.

once i tab on the image, the whole view should push to another view. this my ScrollView.h as the following

@interface PeekPagedScrollViewController : UIViewController <UIScrollViewDelegate>

@property (nonatomic, strong) IBOutlet UIScrollView *scrollView;
@property (nonatomic, strong) IBOutlet UIPageControl *pageControl;

@end

and this is my images array as follow

- (void)viewDidLoad {
    [super viewDidLoad];

    // Set up the image you want to scroll & zoom and add it to the scroll view
    self.pageImages = [NSArray arrayWithObjects:
                       [UIImage imageNamed:@"photo1.png"],
                       [UIImage imageNamed:@"photo2.png"],
                       [UIImage imageNamed:@"photo3.png"],
                       [UIImage imageNamed:@"photo4.png"],
                       [UIImage imageNamed:@"photo5.png"],
                       nil];

so what i need when user touch the photo go to another detailViewController; for example if selected Photo1 this photo enlarge on another viewcontroller so if anybody knows the solution or suitable tutorial

Was it helpful?

Solution 2

Add a UITapGestureRecognizer to the UIScrollView, set the delegate yourself and then this method should give you the index of the tapped image:

- (void)singleTapGestureCaptured:(UITapGestureRecognizer *)gesture{

    CGPoint touchPoint = [gesture locationInView:<yourScrollView>];

    NSUInteger touchedPage = floorf(touchPoint.x / <yourScrollView>.frame.size.width);
    if ([<arrayOfImages> count>] > 1) {

        touchedPage = touchedPage % ([<arrayOfImages> count] - 1);
    }

    NSLog(@"Touched page: %d", touchedPage);

    //Use touchedPage and push the next view controller here

}

To add the gesture recognizer, add these lines into viewDidLoad (or you can use the IB):

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapGestureCaptured:)];
[<yourScrollView> addGestureRecognizer:singleTap];

OTHER TIPS

Better use UITableView and load all images in UITableViewCell using lazy loading, and when you select any image then didSelectRowAtIndexPath will give you index for selected image and in this way you can navigate and pass data from one viewController to nextViewController.

Refer Lazy load images in UITableView

Better use UITableview or GMGridView for this example code following.

[theApp.fullViewModeObject.statusDicts addObjectsFromArray:statusDicts];
[self.navigationController pushViewController:theApp.fullViewModeObject animated:YES];

theApp.fullViewModeObject is fullviewmode class object [theApp.fullViewModeObject.statusDicts] is array for loading image details
