crashed in iPhone 6 about tocropviewcontroller HOT 12 CLOSED

Hi Arjun! Glad you're enjoying the app!

Oh dear! I remember seeing that once or twice during development in the simulator, but never on the device. I did a bit of research just now and it looked like it's an issue that arrises if a memory warning occurs.

How big is the image you were trying to crop?

hi tim thanks for reply
images size is 1.9 MB

Hrmm, and what was its pixel resolution? When you're manipulating it in the crop controller, it gets decompressed into raw pixel data, which can take up a lot more memory than what's on disk.

I might have to look into making the controller a bit more memory efficient. Or if worse comes to worse, you can always downscale your images before sending them to the crop controller.

750X1334 resolution.i was pick image in image picker controller and pass to image in cropview.when i click done button it will happen .

from tocropviewcontroller.

Aw. That's absolutely tiny. That shouldn't be causing any memory issues. :S

I'm not sure then. Is it happening reliably each time you use the cropper?
And, just in case, are you doing any rotations to the image?

No, i am not doing any rotation,it will come 4 times each of 10 using crop. and when i click done button also show in log -----<<<>>>> <UIVisualEffectView 0x15f66cf10> is being asked to animate its opacity. This will cause the effect to appear broken until opacity returns to 1.

Hrmm... there's literally none of my code in that call stack. I wonder what's going on. :S

iMAGE RESOLUTION (3264.0, 2448.0) orientation 0 scale 2.000000 and returncropped image resolution is {6528, 4892}
when convert into byte 1203580 bytes using
let imageData = UIImageJPEGRepresentation(image, 0.0)
any idea reduse size but not dimension ?

from tocropviewcontroller.

[self.image croppedImageWithFrame:cropFrame angle:angle] when call this method dimention is double. how to change?

from tocropviewcontroller.

My app is crashing as well when trying to crop a very large image. The image is 3.3MB in size and with resolution 3264x2448 which is a photo taken using iPhone 6 plus. If I don't reduce the crop area but use the full size and press the Done button, half of the time it will crash the app with error 'Received memory warning.' Sometimes I can even see the white apple logo after the crash but the device is not restarting, it just go back to home screen :)

I have uploaded a sample image that i used here:

hi lori57

please change UIImage+CropRotate.m file

• (UIImage *)croppedImageWithFrame:(CGRect)frame angle:(NSInteger)angle
  {
  UIGraphicsBeginImageContextWithOptions(frame.size, YES, 1.0f);
  {
  }
  }

hope it help

from tocropviewcontroller.

Oh! That actually did it! I didn't think to look there; I was looking at my actual layout code to try and figure out what was going on. I can't believe I completely missed that.

Anyway, I've updated it in the repo now (I elected to use the image.scale property instead of 1.0f just in case). Please give it a try and tell me if it's working for you now (And I'll reopen this issue).

Thanks again!
