Question

Image of my screen 我想显示一个带有地点选择器的地图。我创建了所需的API，并将其添加到AppDelegate.m中。然后，我在视图控制器中实现了以下代码：

 - (void)location
{
    GMSPlacePickerConfig *config = [[GMSPlacePickerConfig alloc] initWithViewport:nil];
    GMSPlacePickerViewController *placePicker = [[GMSPlacePickerViewController alloc] initWithConfig:config];
    placePicker.delegate = self;
    [self presentViewController:placePicker animated:YES completion:nil];
}

- (void)placePicker:(GMSPlacePickerViewController *)viewController didPickPlace:(GMSPlace *)place {
    [viewController dismissViewControllerAnimated:YES completion:nil];

    NSLog(@"Place name %@", place.name);
    NSLog(@"Place address %@", place.formattedAddress);
    NSLog(@"Place attributions %@", place.attributions.string);
}

- (void)placePickerDidCancel:(GMSPlacePickerViewController *)viewController {
    [viewController dismissViewControllerAnimated:YES completion:nil];

    NSLog(@"No place selected");
}

我得到了GMSPlacePickerViewController但在我的针脚下没有地图。有什么想法吗？

使用视口初始化placePickerConfig时：nil默认为用户的当前位置。执行所有这些操作之前，请确保您具有用户的位置。像这样初始化GMSPlacePickerConfig时，通过提供恒定的地图坐标来测试地图：

let center = CLLocationCoordinate2DMake(-33.86, 151.20)
let northEast = CLLocationCoordinate2DMake(center.latitude + 0.001, center.longitude + 0.001)
let southWest = CLLocationCoordinate2DMake(center.latitude - 0.001, center.longitude - 0.001)
let viewport = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)

然后使用视口初始化placePickerConfig。我使用了swift，因为我不了解obj-c，但是您可以轻松地将其转换。如果这是问题所在，则需要先获取用户的坐标

使用GMSPlacePickerViewController IOS时看不到地图
