I’ve been having a problem to show large images on a scrollview, the images

  • 0

I’ve been having a problem to show large images on a scrollview, the images are 2,4 – 4,7 MB. It runs fine on the 3GS and on the simulator. But whenever I try to run on a 3G or iPod Touch 2G, it crashes.

I searched across the web and found the “imageNamed is evil” article. Ok I changed all my image calls to imageWithContentsOfFile: but it still crashes, the only different that I see is that now images are deallocated after I leave the view just fine. But the memory usage is still very high.

Here is a screenshot of Instruments.

First peak is a video I show at startup, then the tableview shows a lot of images, until then no problems.

When I enter a 1,1mb – 2576 x 1000 picture

When I enter a 4,8mb – 7822 x 1000 picture

By the way the app was tested on iOS 4 and 3.1.2

Do you have any tips? Because this problem is driving me nuts.

Since now thanks a lot!

    I ended up using UIWebView, I had to use smaller (in MB, not dimensions) images but it’s working on, the only problem Is that I can’t zoom… Using the scalePageToFit I can zoom but the image fits horizontally not vertically, that sux.

    I will try to keep this issue updated.

    If someone has this problem I would advice to use webview or an adapter version of three20 image viewer that handles memory better.
