如何在MKMapView中居我当前的位置？ [英] How to center my current location in MKMapView?

问题描述

我使用 showUserLocation MKMapView 中显示当前位置 $ c>启用。我还想将 mapview 集中到用户当前位置以及缩放的位置图。请帮我解决这个问题，因为我在stackoverflow上没有得到任何其他类似问题的帮助。

I am showing the current location in MKMapView by using showUserLocation enables. I also want to center the mapview to the user current location and also the zoomed map of location. Please help me regarding this as I don't get any help from other similar questions on stackoverflow.

我的代码如下：

- (void)viewDidLoad {
  [super viewDidLoad];
  [mapView setMapType:MKMapTypeStandard];
  [mapView setZoomEnabled:YES];
  [mapView setScrollEnabled:YES];
  [mapView setCenterCoordinate:mapView.userLocation.location.coordinate animated:YES];
  [mapView setDelegate:self];
}

推荐答案

以中心用户位置为准您可以使用以下代码：

For centering on user location, you can use the following code:

[mapView setCenterCoordinate:mapView.userLocation.location.coordinate animated:YES];

要放大特殊地点，你应该研究一下这些地区（ MKCoordinateRegion ）计算并运行，计算您所在地区的值并使用调用显示它：

For zooming on special locations, you should study how the regions (MKCoordinateRegion) are counted and work, count your values for the region and display it using call:

[mapView setRegion:myRegion animated:YES];
