The class has been improved through several Xojo releases, offering more options and modernizing its look and feel to match recent iOS releases. In this post, let’s talk about using one of those small but useful improvements to MobileImagePicker with Xojo 2026r2, the SelectionLimit property.

On previous releases, when using the MobileImagePicker to select pictures from the device gallery (using MobileImagePicker.Sources.Photos), the user was allowed to choose as many pictures as they wanted to… but maybe that was not what your app logic expected!

Now you can use MobileImagePicker.SelectionLimit to set that expectation, so the user must comply with the limits your app needs.

If the logic of any of your existing apps allows the user to select as many pictures as they want, then there is nothing you need to do, the existing code will continue to work as expected. That is because the default value of the MobileImagePicker.SelectionLimit is 0. Or if you want to be more explicit, you can set the property to MobileImagePicker.UnlimitedSelection.

When setting the MobileImagePicker.SelectionLimit property to any other value, the iOS modal dialog will display that limit to the user so they know exactly what is expected.

Do you want to see it in action? Open the iOS > ImagePicker example project from the IDE. Once opened, select the Pressed event handler from the Button1 item in the project navigator to access the associated Code Editor. Then, modify the existing code like this:

ImagePicker.Source = MobileImagePicker.Sources.Photos
ImagePicker.SelectionLimit = 2
ImagePicker.Show()

We set the maximum limit of selected images to two. Run the app in the simulator, click on the Pick Pictures button, and the following modal will be shown, allowing you to choose a maximum of two images:

In summary

Alongside the big features highlighted in each Xojo release, there are a lot of other improvements and helpful additions. Take a look at the full list of updates in the Release Notes.

Select Multiple Images

Starting with Xojo 2025r2, we’ve updated the MobileImagePicker for iOS to use a more modern controller under the hood. As a result, users can now select multiple photos at once (depending on the needs of your app) and also take advantage of additional features available in the new image selector.

In addition, as a result of this change, we’re now able to capture and provide more complete EXIF metadata for each selected image.

The best part is, you don’t need to change a single line of code to take advantage of these new capabilities. However, due to the asynchronous nature of iOS, the Selected event handler of the MobileImagePicker will now fire once for each image the user selects. Be sure to account for that in your app’s logic. You may want to check out the updated “MobilePicture-Metadata” example project for guidance.

Choose Your Camera Source

When MobileImagePicker.Source was set to Camera, it defaulted to the device’s rear camera, which works well for most scenarios. However, some apps may need to use the front camera by default. While users could always switch cameras with a tap, it’s even better if your app can save them that extra step.

Now, if your app requires the front camera by default, you can set the source to the new enum value: Source.FrontCamera.
