A view allowing user to specify a rectangle area in an image. The user can drag the corner to resize it, move the entire bounding box, or use 2 fingers like a pinch gesture to move and resize the bounding box. The color and size of the dots on the corner can be customized.
Very easy! It is created to be a drop-in component, so no static library, no extra dependencies.
Just copy ImageCropView.h and ImageCropView.m to your project,
and implement ImageCropViewControllerDelegate protocol.
Use it like UIImagePicker:
- (void)cropImage:(UIImage *)image{
ImageCropViewController *controller = [[ImageCropViewController alloc] initWithImage:image];
controller.delegate = self;
[[self navigationController] pushViewController:controller animated:YES];
}- (void)ImageCropViewController:(ImageCropViewController *)controller didFinishCroppingImage:(UIImage *)croppedImage{
image = croppedImage;
imageView.image = croppedImage;
[[self navigationController] popViewControllerAnimated:YES];
}- (void)ImageCropViewControllerDidCancel:(ImageCropViewController *)controller{
imageView.image = image;
[[self navigationController] popViewControllerAnimated:YES];
}Using FXBlurView, you can now blur the parts of the image outside the crop area. This is not for blurring the final cropped image. Just set the blurredBackground property in the same place you set the delegate, like so:
controller.blurredBackground = YES;To set the minimum height and width of a cropped image, simply change the IMAGE_MIN_HEIGHT and IMAGE_MIN_WIDTH variables at the top of ImageCropView.m.
The project comes with a working example (as target ImageCropView) to demostrate the usage.
