Place Views Relative to Cutout
In order to add a view related to the size and/or position of the Anyline cutout view,
implement the ALScanViewDelegate
method scanView:updatedCutoutWithPluginID:frame:
.
This method is called each time the Anyline SDK updates the cutout view. In order to use this delegate, you have to subscribe to events in your scan view by setting a delegate:
-
Swift
-
Objective-C
scanView.delegate = self
scanView.delegate = self;
Then, you may use the frames provided by the following method as a way to say, position any UI guides displayed over the scan view:
-
Swift
-
Objective-C
func scanView(_ scanView: ALScanView, updatedCutoutWithPluginID pluginID: String, frame: CGRect) {
self.positionOverlayOnCutoutWithFrame(frame)
}
- (void)scanView:(ALScanView *)scanView updatedCutoutWithPluginID:(NSString *)pluginID frame:(CGRect)frame {
[self positionOverlayOnCutoutWithFrame:frame];
}
The pluginID
parameter can be used to distinguish between children plugins cutouts in a running plugin composite. If a cutout is hidden, a CGRectZero
value will passed by the frame.
