QUESTION
i have a map kit view and when the app loads, it gets the users current location and tracks it. It then runs a function to focus on the users location which I've also linked to a button so the user can navigate around and then focus back to their location span.
In this function i set the span to 0.01 but when i print the span value its different. When the app runs and focuses for the first time, the latitude span is printing at 0.00745918279325508
Then when i hit the focus button which runs the exact same function, the lat span is printing at 0.0102124663369167 and its noticeably zoomed out
Why is it doing this when I've already set it to 0.01? here is my code:
...ANSWER
Answered 2017-Sep-18 at 10:20According to Apple docs:
When setting a new region, the map may adjust the value in the region parameter so that it fits the visible area of the map precisely. This is normal and is done to ensure that the value in the region property always reflects the visible portion of the map. However, it does mean that if you get the value of that property right after calling this method, the returned value may not match the value you set.
So, when you apply span, it creates the region which is best fit for your request. It will not be exactly same as what you have requested.
