Iphone 从MapView中选择位置

我在考虑一个应用程序，用户可以在iphone应用程序上选择一个位置。我在谷歌上搜索了一下，没有发现任何有用的东西

我的问题是，是否可以让用户使用MapKit/CLLocation从iphone应用程序中选择位置？如果是，请帮助我从哪里开始

谢谢

看一看。答案不仅告诉您如何获取坐标，还告诉您如何在地图上放置pin（注释）。

您可以在地图上添加长按手势识别器：

UILongPressGestureRecognizer* lpgr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 1.5;
lpgr.delegate = self;
[self.map addGestureRecognizer:lpgr];
[lpgr release];

在handle long press方法中，获取CLLocationCordinate2D：

- (void) handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer {
if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
    /*
     Only handle state as the touches began
     set the location of the annotation
     */

    CLLocationCoordinate2D coordinate = [self.map convertPoint:[gestureRecognizer locationInView:self.map] toCoordinateFromView:self.map];

    [self.map setCenterCoordinate:coordinate animated:YES];

  // Do anything else with the coordinate as you see fit in your application

   }
}
