Question

iPad crash or how to catch this

Hi, first of all Titanium is a wonderful software, thank You for it.

This shall be a small app for our customer, some kind of eBook, he wants just to swipe through pages.
So nothing really special about this, working perfectly in iPad simulator, but crashing after random swipe actions.
Somebody an idea ?

Thanks

Now shortly to my problem:

var scrollData = [];
for (i=0; i<=199; i++) {        
    var myV = Titanium.UI.createImageView({
        top: 0,
        height:fullSight,
        width: 1024,
        image: 'book/' + bigChapter[i] + '.jpg'
    });
    checkSpecialPage(i);
     v.push(myV);
     scrollData.push(v[i]);    
}
var allChapters = v;

var view1 = Titanium.UI.createScrollableView({
    views: scrollData,
    backgroundColor:'#FFF',
    showPagingControl:false,
    pagingControlHeight:30,
    maxZoomScale:2.0,
    currentPage:0,
        showVerticalScrollIndicator:false,
        showHorizontalScrollIndicator:false
});
controllerWindow.add(view1);

So it's clear

You have 200 of 1024px wide images that you load on the device, which is bad. I guess you need to find a way to add/close the images one by one, or at least less images at once.

Answer 2

Run the application from xcode on the ipad and try to see on the gdb debugger console where is crashing.

Thanks, just done. It is generating low memory crashes:
