Photo orientation issue in Three20's TTPhotoViewController ?

Question

Hey There,

I'm currently having some troubles with TTPhotoViewController : I try to display some photos (taken from my iPhone 3GS camera), and the orientation of the displayed pictures are almost always erroneous ...

I mean that for example a photo taken in landscape mode will sometimes be displayed correctly, sometimes it will be upside down, sometimes it will be rotated ...

I've also noticed that a photo taken in portrait mode will be rotated (and so will take more than the whole screen), but rotating the iPhone will make it fit the screen well ...

I think I'm going mad :) any help would be greatly appreciated, thanks by advance.

EDIT : It seems it's a matter of size. I tried to downscale my picture and TTPhotoViewController doesn't screw up anymore, and then I try to rescale it to its initial size and the problem is occuring again. I can't understand that problem as a "memory limit" one, as my picture was taken with my iPhone ; moreover a UIImageView display it well ...

If anyone has a suggestion ...

Answer 1

You probably set size: attribute of the photoSource to some wrong value.

Edit: Unfortunately i don't have another suggestion for your problem, however i have a warning. You should definitely scale your image before display, 1536x2048 is way too large for iphone to handle, and totally unnecessary for a 320x480 screen. Otherwise you are sure to have app crashes due to low memory in the future - if not now.
