Zoom to Geometry

RoshnaDsouza — Tue, 28 Apr 2015 04:06:57 GMT

-(void)zoomToGeometry:(AGSGeometry*)geometry withPadding:(CGFloat)padding animated:(BOOL)animated; doesn't zoom to geometry when the map is rotated , it works fine when the map rotation angle is 0.

Hi Roshna Dsouza,

I just tried it and it works for me. Can you share your code or explain what you are trying to do?

I have to check if the geometry is zoomed to a particular resolution It should be visible to the user/

This code below works perfectly fine when maps rotating angle is 0. but when rotating angle is other than 0 ,

[self.mapView zoomToGeometry:[self.editLayerManager geometry] withPadding:[defaultScale floatValue] animated:YES];

doesn't zoom to exact geometry with padding.

AGSMutableEnvelope *visibleAreaEnvelope = [self.mapView.visibleArea.envelope mutableCopy];

float zoomFactor = [levelScale doubleValue]/self.mapView.resolution;

[visibleAreaEnvelope centerAtPoint:[self.editLayerManager zoomToGeometryCenter]];

[visibleAreaEnvelope expandByFactor:zoomFactor];

if (![visibleAreaEnvelope containsEnvelope:[self.editLayerManager geometryEnvelope]]) {

[self.mapView zoomToGeometry:[self.editLayerManager geometry] withPadding:[defaultScale floatValue] animated:YES];

}

} else {

[self.mapView zoomToResolution:[levelScale doubleValue] withCenterPoint:[self.editLayerManager zoomToGeometryCenter] animated:YES];

}

Can you provide a demo project as a way to reproduce the issue? It will help us in debugging the problem, if there is one.
