How can I set my mapview to automatically zoom in on user's current location?
提问by user1953744
When I click on the "Map" button in my tab bar, it pulls up my Map View Controller, and shows the user's current location on the mapview (I'm using the following code):
当我点击标签栏中的“地图”按钮时，它会拉出我的地图视图控制器，并在地图视图上显示用户的当前位置（我正在使用以下代码）：
[mapview setShowsUserLocation:YES];
Super easy. But if I want the map to automatically zoom in on the user's current location, how do I go about doing this (in xCode)?
超级容易。但是，如果我希望地图自动放大用户的当前位置，我该怎么做（在 xCode 中）？
Thanks :)
谢谢 ：）
