ios7 - MKMapView禁用旋转

Question

我有一个使用MKMapView作为主要显示区域的应用程序。这应该始终朝北。但是无意间快速滑动并旋转，会导致指南针出现。

有什么办法可以阻止这种情况的发生并保持 View 向北锁定？我在这里看到了一些提示，但没有任何内容指的是任何内置机制。

Answer 1

快速浏览一下MKMapView上的Apple文档:

rotateEnabled A Boolean value indicating whether the map camera’s heading information is used.

@property(nonatomic, getter=isRotateEnabled) BOOL rotateEnabled Discussion When this property is set to YES and a valid camera is associated with the map, the camera’s heading angle is used to rotate the plane of the map around its center point. When this property is set to NO, the camera’s heading angle is ignored and the map is always oriented so that true north is situated at the top of the map view.

因此，您可以尝试将mapview rotationEnabled属性设置为“NO”。
