Question

I am working with MvvmCross Monotouch.

Here is the Binding Code that actually works very well on the iOS Simulator.

{ this, "{'Title':{'Path':'NavigationBarTitle'}}

However, it does not work when I deploy it on my real iPad (iPad 2).

Application Output:
===================
MvxBind: Warning:   0.69 Failed to create target binding for from NavigationBarTitle to Title

I am glad to see it works on the iOS Simulator but, is there any reason why it does not work on the real iPad?

Answer 1

One situation I’ve seen this type of error occur in is in release builds where the monotouch linker optimises the image size and removes the apparently unused property required for binding.

To workaround this, I generally include a fake bit of code to trick the linker into including the required properties – e.g. Here’s a monodroid sample file which does the same sort of thing:

This is one of the disadvantages of using mvvmcross currently – it can lead to larger binary image sizes.
