A simple, customizable square scale and crop view controller
##Usage
Simply import the cropper with #import BASSquareCropperViewController.h
Listen to the following delegate methods:
- (void)squareCropperDidCropImage:(UIImage *)croppedImage inCropper:(BASSquareCropperViewController *)cropper- (void)squareCropperDidCancelCropInCropper:(BASSquareCropperViewController *)cropper
and handle them according to how your app should function.
Initialize the cropper with an image and a minimum side length as so (0.0f side length means no limit):
BASSquareCropperViewController *squareCropperViewController = [[BASSquareCropperViewController alloc] initWithImage:imageToCrop minimumCroppedImageSideLength:400.0f];
Don't forget to set the delegate! squareCropperViewController.squareCropperDelegate = self;
From here, it's recommended to present this view controller modally, but not required.
If you want to retrieve the finished cropped rect versus the original image, simply access the property cropRect on your BASSquareCropperViewController in the delegate callback before you dismiss it.
##Customization
The following properties can be set to adjust the look and feel of the cropper:
@property (nonatomic, strong) UIColor *backgroundColor;
@property (nonatomic, strong) UIColor *borderColor;
@property (nonatomic, strong) UIColor *excludedBackgroundColor;
@property (nonatomic, strong) UIFont *doneFont;
@property (nonatomic, strong) UIColor *doneColor;
@property (nonatomic, copy) NSString *doneText;
@property (nonatomic, strong) UIFont *cancelFont;
@property (nonatomic, strong) UIColor *cancelColor;
@property (nonatomic, copy) NSString *cancelText;
Simply initialize the cropper and set whichever of these as is fitting, for example:
squareCropperViewController.backgroundColor = [UIColor whiteColor];
squareCropperViewController.borderColor = [UIColor redColor];
squareCropperViewController.doneColor = [UIColor orangeColor];
squareCropperViewController.doneFont = [UIFont fontWithName:@"Avenir-Roman" size:30.0f];
squareCropperViewController.doneText = @"FINISHED";
squareCropperViewController.cancelColor = [UIColor greenColor];
squareCropperViewController.cancelFont = [UIFont fontWithName:@"Avenir-Black" size:25.0f];
squareCropperViewController.cancelText = @"STOP";
squareCropperViewController.excludedBackgroundColor = [UIColor blackColor];
This would look like hot garbage, but you get the idea. Anything left unmodified will be defaulted to what is shown in the screenshots.
