点击折线没有任何作用 - Google Maps IOS SDK

Question

阅读过类似的帖子并尝试了他们的解决方案，但对我没有任何效果。通过 XCode 6.x 在 IOS 模拟器上运行超级简单的 Google Maps SDK 1.9.x 示例，当我点击（好的，真的在模拟器中点击，这有什么不同吗？）没有任何记录，因为代码会让我相信它会，所以看起来 didTapOverlay 永远不会被调用。

#import "ViewController.h"
#import <GoogleMaps/GoogleMaps.h>

@interface ViewController ()

@end

@implementation ViewController {
    GMSMapView *mapView_;

}


- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    // Create a GMSCameraPosition that tells the map to display the
    // coordinate -33.86,151.20 at zoom level 6.
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:43.5157
                                                            longitude:-114.2933
                                                                 zoom:14];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled = YES;
    mapView_.settings.compassButton = YES;
    mapView_.settings.myLocationButton = YES;


    GMSMutablePath *path2 = [GMSMutablePath path];
    [path2 addCoordinate:CLLocationCoordinate2DMake(43.50618099,-114.34367)];
    [path2 addCoordinate:CLLocationCoordinate2DMake(43.50624301,-114.343572)];
    [path2 addCoordinate:CLLocationCoordinate2DMake(43.50635399,-114.343333)];

    GMSPolyline *rectangle2 = [GMSPolyline polylineWithPath:path2];
    rectangle2.spans = @[[GMSStyleSpan spanWithColor:[UIColor redColor]]];
    rectangle2.tappable = true;
    rectangle2.strokeWidth = 10.f;

    rectangle2.map = mapView_;

    NSLog(@"The code runs through here!");

    self.view = mapView_;

Answer 1

首先，如果您可以将相机启动到以下位置，将会更容易：

 GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:43.5157
                                                            longitude:-114.34367
                                                                 zoom:14];

这样您就可以在相机附近轻松看到您的折线。

然后在您的ViewController.h 头文件中，将您的界面更改为以下内容：

@interface ViewController : UIViewController<GMSMapViewDelegate>

所以你的视图控制器将是一个 GMSMapViewDelegate。

最后，在您的 self.view = mapView_; 下方添加以下行：

mapView_.delegate = self;

这一行会将您的视图控制器（即 GMSMapViewDelegate）分配给您的 mapView_ 的 delgate，以便您的 mapView_ 的委托将是 GMSMapViewDelegate，并且会调用 didTapOverlay 方法。
