问题描述
我只是创建项目，并在我的第一个viewController中添加了 MKMapView ，但是我看到的是！地图完全卡住，意味着无法滚动/放大等.
I just create project and in my first viewController added MKMapView but what I'm seeing! Map is totally stuck means not able to scroll/zoom in-out and etc.
在Xcode 9中添加Map是Bug还是做任何错误?最新系统是否需要其他设置?
Is it Bug or doing any mistake to add Map in Xcode 9? Is there any additional setup required for latest system?
我没有写任何代码，所以这里不添加我的代码.
I did not write any code so here not adding my code.
推荐答案
MKMapView在XCode 9中非常缓慢...这是苹果方面的已知问题.如果要获得更快的性能，请使用移动设备而不是模拟器进行测试.请注意，此时XCode 9不适用于iOS 11.1.2.发现了很难的方法.
MKMapView is very sluggish in XCode 9... this is a known problem on Apple's side. If you want to see faster performance, use your mobile device rather than the simulator for testing. Be advised that XCode 9 doesn't work with iOS 11.1.2 at this point. Found that out the hard way.
在这一点上，我的应用程序不需要滚动，但是我必须按住约5-7秒钟才能显示我的图钉.
At this point, my app doesn't require scrolling, but I am having to press and hold for about 5 - 7 seconds to get my pin to appear.
好玩的时光.
