Multi resolution bitmaps

FMX TMS iCL
1

I'm just getting started with my first iOS app using XE6 and iOS 7.  I like the native UI capabilities that come with the iCL but I've noticed that for icons for toolbar items or tab bar items you can only specify one bitmap of a specific size.  My app is going to be used on both retina and non-retina ipads so I need to provide both sizes of bitmaps.  How do you do this with the current iCL for XE6?  If there is no way, when will this capability be added?


Thanks

Hi, 


You need to create 2 images, for instance 'MyImage.png' with the size for non-retina screens and 'MyImage@2x.png' for retina screens. Add them both to your application through the deployment window.

You can access the native control and add the image programmatically:

TMSFMXNativeUIToolBar1.Items[0].Item.setImage(TUIImage.Wrap(TUIImage.OCClass.imageNamed(NSStr('MyImage'))));

Depending on the screen size, it will automatically use one of the added images.

You will need to add the units iOSApi.UIKit and iOSApi.Foundation

Kind Regards, 
Pieter
