SBSDKImageEditingViewController
@interface SBSDKImageEditingViewController : UIViewController
A UIViewController subclass to show and edit an image. The user can move edge and corner handlers to redefine the polygon manually and rotate the image in 90 degree steps (counter) clockwise. This class cannot be instanced from a storyboard. Instead it is installing itself as a child view controller onto a given parent view controller.
-
The uncropped input image. If polygon is nil, the receiver tries to detect and set a polygon from the image. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic, strong, nonnull) UIImage *image;
Swift
var image: UIImage { get set }
-
The queue being used to detect a document on the image. Defaults to a serial concurrent queue.
Declaration
Objective-C
@property (nonatomic, strong, nonnull) dispatch_queue_t processingQueue;
Swift
var processingQueue: DispatchQueue { get set }
-
The current polygon. If nil, the default, fully enclosing, polygon is used. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic, copy, nullable) SBSDKPolygon *polygon;
Swift
@NSCopying var polygon: SBSDKPolygon? { get set }
-
The number of clockwise rotations.
Declaration
Objective-C
@property (nonatomic) NSInteger rotations;
Swift
var rotations: Int { get set }
-
The rendering color of non-snapped edges. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic, strong, nonnull) UIColor *edgeColor;
Swift
var edgeColor: UIColor { get set }
-
The rendering color of magnetically snapped edges. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic, strong, nonnull) UIColor *magneticEdgeColor;
Swift
var magneticEdgeColor: UIColor { get set }
-
The color of anchor points. The default value is nil, which means that anchors will be white. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic, strong, nullable) UIColor *anchorPointsColor;
Swift
var anchorPointsColor: UIColor? { get set }
-
The width of the edges. The default value is 2. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic) CGFloat edgeLineWidth;
Swift
var edgeLineWidth: CGFloat { get set }
-
The cropped and rotated image. This is the final result of the receiver. Must be called on the main-thread!
Declaration
Objective-C
@property (nonatomic, readonly, nullable) UIImage *croppedImage;
Swift
var croppedImage: UIImage? { get }
-
Enables or disables crop functionality. Default is YES.
Declaration
Objective-C
@property (nonatomic, getter=isCropEnabled) BOOL cropEnabled;
Swift
var isCropEnabled: Bool { get set }
-
Enables or disables rotation functionality. Default is YES.
Declaration
Objective-C
@property (nonatomic, assign, unsafe_unretained, readwrite, getter=isRotationEnabled) BOOL rotationEnabled;
Swift
var isRotationEnabled: Bool { get set }
-
The insets of the contents: image and handles. Defaults to (12, 12, 12, 12).
Declaration
Objective-C
@property (nonatomic) UIEdgeInsets contentInsets;
Swift
var contentInsets: UIEdgeInsets { get set }
-
Delegate for result callback methods.
Declaration
Objective-C
@property (nonatomic, weak, nullable) id<SBSDKImageEditingViewControllerDelegate> delegate;
Swift
weak var delegate: SBSDKImageEditingViewControllerDelegate? { get set }
-
Designated initializer. Installs the receiver as child view controller onto the parent view controllers view using its entire bounds area.
Declaration
Objective-C
- (nonnull instancetype)initWithParentViewController: (nonnull UIViewController *)parentViewController containerView: (nonnull UIView *)container;
Swift
init(parentViewController: UIViewController, containerView container: UIView)
Parameters
parentViewController
The view controller the newly created instance is embedded into.
container
The view to embed the receivers view into. Must be a descendant of parentViewControllers view.
-
Asks the controller to rotate input image
Declaration
Objective-C
- (void)rotateInputImageClockwise:(BOOL)clockwise animated:(BOOL)animated;
Swift
func rotateInputImageClockwise(_ clockwise: Bool, animated: Bool)
Parameters
clockwise
The rotation direction. If set YES, rotates clockwise, counterclockwise otherwise.
animated
If set to YES, animates the rotation.
-
Updates the navigation bars buttons of the receiver by calling the appropriate delegate functions.
Declaration
Objective-C
- (void)updateNavigationBarItems;
Swift
func updateNavigationBarItems()
-
Updates the toolbars buttons of the receiver by calling the appropriate delegate functions.
Declaration
Objective-C
- (void)updateToolBarItems;
Swift
func updateToolBarItems()
-
Tells the receiver to apply changes immediately. Calls the appropriate delegate method when finished.
Declaration
Objective-C
- (void)applyChanges;
Swift
func applyChanges()
-
Tells the receiver to cancel changes immediately. Calls the appropriate delegate method.
Declaration
Objective-C
- (void)dismissChanges;
Swift
func dismissChanges()
