UIImagePickerController - crops picture to square (in portrait)

Question

I'm using the UIImagePickerController to take and edit a picture. it works fine in landscape, but in portrait it will crop the picture into a square (does not allow to reduce the image to fit fully into the square crop field like in landscape. Any ideas?

code:

-(IBAction)initCamera:(id)sender{

//Init imagePicker instance
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setDelegate:self];

[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setShowsCameraControls:YES];
[imagePicker setAllowsEditing:YES];

[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}

Solution 1

Check out GKImagePicker library, it allows to set your custom image crop area, like this:

self.imagePicker = [[GKImagePicker alloc] init];
self.imagePicker.cropSize = CGSizeMake(320, 90);
self.imagePicker.delegate = self;

[self presentModalViewController:self.imagePicker.imagePickerController animated:YES];

I know its really late to answer this question, But someone may find this helpful.

Change

[imagePicker setAllowsEditing:YES]; 

To

[imagePicker setAllowsEditing:NO];

Thanks, Jay

You can provide a custom cropping UI, but there is no way to change just the cropping rectangle of the standard one.

This link might help with that.

Thanks. I'm just wondering why cropping works ok for landscape (I can fit the whole image into the cropping square, so nothing gets lost), but not for portrait, where it doesn't allow to fit the image into the square.

it doesn't allow to set camera as sourcetype. It works with gallery only!

[Andrey Zverev]

@George it allows to use images from both gallery and camera.

I updated the answer to include a sample line for setting sourceType

@JoshLehman I am having same problem and this looks perfect but I can not see how you can set the source.

@RecycledSteel You should use self.imagePicker.imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;

This simply disables cropping. Imagine a use-case where someone wanted to upload a full-size portrait, yet wanted to crop out parts of a landscape photo.

[Jay Pandya]

@carbocation yes that can be a case. But thats whole new functionality i guess, that you can manage by checking imageOrientation property of image in didFinishPickingImage: delegate method of UIImagePickerController

When i add GK Library and images , it gives me errors . What to do .?
