SBSDKMRZScannerViewController Class Reference


                    
                    
                    delegate

The delegate. See SBSDKMRZScannerViewControllerDelegate protocol. Weak.

Declaration

Objective-C

@property (nonatomic, weak, nullable) id<SBSDKMRZScannerViewControllerDelegate> delegate;

Swift

weak var delegate: SBSDKMRZScannerViewControllerDelegate? { get set }


                    
                    
                    maxNumberOfAccumulatedResults

The maximum number of results to be accumulated when live-recognizing machine readable zones on sample buffers. This sets the second part of a requiredNumberOfEqualAccumulatedResults-of-maxNumberOfAccumulatedResults selector, e.g. 2 of 4 results must be equal. To make the selector less strict, select a higher value, e.g. 2 of 5 or even 2 of 6. Setting a value lower than requiredNumberOfEqualAccumulatedResults will throw an exception. Values less-than-or-equal to 0, will effectively turn off the result accumulation. The default value is 4.

Declaration

Objective-C

@property (nonatomic) NSUInteger maxNumberOfAccumulatedResults;

Swift

var maxNumberOfAccumulatedResults: UInt { get set }


                    
                    
                    requiredNumberOfEqualAccumulatedResults

The minimum number of equal results in the accumulator when live-recognizing machine readable zones on sample buffers. This sets the first part of a requiredNumberOfEqualAccumulatedResults-of-maxNumberOfAccumulatedResults selector, e.g. 2 of 4 results must be equal. To get less false positive results make the selector more strict by selecting a higher value, e.g. 3 of 4 or even 4 of 4. Setting a value higher than maxNumberOfAccumulatedResults will throw an exception. Values less-than-or-equal to 0, will effectively turn off the result accumulation. The default value is 2.

Declaration

Objective-C

@property (nonatomic) NSUInteger requiredNumberOfEqualAccumulatedResults;

Swift

var requiredNumberOfEqualAccumulatedResults: UInt { get set }


                    
                    
                    -initWithParentViewController:parentView:delegate:

Installs the receiver as child view controller onto the parent view controllers view using its entire bounds area.

Declaration

Objective-C

- (nullable instancetype)
    initWithParentViewController:
        (nonnull UIViewController *)parentViewController
                      parentView:(nonnull UIView *)parentView
                        delegate:
                            (nullable id<SBSDKMRZScannerViewControllerDelegate>)
                                delegate;

Swift

init?(parentViewController: UIViewController, parentView: UIView, delegate: SBSDKMRZScannerViewControllerDelegate?)

Parameters

`parentViewController`	The view controller the newly created instance is embedded into.
`parentView`	The view the newly created instance is embedded into.
`delegate`	The delegate of the receiver. If nil and the parentViewController conforms to the SBSDKMRZScannerViewControllerDelegate protocol, the parentViewController is automatically set as delegate.

Return Value

New instance of SBSDKMRZScannerViewController.
