On iOS 7, the app height and width needs to be set to device height and width to view port to resolve the issue. Below is a sample code to be included in onModuleLoad to resolve the issue.
ViewPort viewPort = new MGWTSettings.ViewPort(); viewPort.setTargetDensity(DENSITY.MEDIUM); viewPort.setUserScaleAble(false) .setMinimumScale(1.0).setMinimumScale(1.0).setMaximumScale(1.0); viewPort.setHeightToDeviceHeight(); viewPort.setWidthToDeviceWidth();
