Xamarin Ios String Format issue

Question

Hi,

We have encountered an issue in our mobile app displaying a formatted string. This happens only in iPhone. On Android it works perfectly.
The code is like:

        public string FormatHours(double hours)
        {
            int actualHours = (int)hours;
            int actualMinutes = (int)((hours - Math.Truncate(hours)) * 60);

            return string.Format(TranslationService.Get("FormatString.Time"), actualHours, actualMinutes);
        }

This is defined in our viewmodel, and we use that property normally via data-binding.
The FormatString.Time value is: hh\h:mm\m

In the Android version the time is correctly formatted like: 4h 16m
But in Ios we show the string format placeholder all the time like: hh\h:mm\m

Any idea what might be the problem?

Tried on different locales, but same issue.

Hello,

Welcome to Microsoft Q&A!

I guess the string format is invalid on iOS .

You can simply combine the string manually as below .

   public string FormatHours(double hours)  
           {  
               int actualHours = (int)hours;  
               int actualMinutes = (int)((hours - Math.Truncate(hours)) * 60);  
     
               return actualHours + "h " + actualMinutes + "m";  
     
           }
