所以我在地图上散布了一堆注释......一切都只是花花公子.现在我需要能够设置地图的位置和缩放,以便它们完全适合.我怎样才能做到这一点？

我在找到MKAnnotationView异步请求完成后更新自定义映像的方法时遇到问题,并提供有关注释状态的信息.到目前为止,我有这个:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {

    static NSString *identifier = @"EstacionEB";   
    if ([annotation isKindOfClass:[EstacionEB class]]) {
        EstacionEB *location = (EstacionEB *) annotation;

        CustomPin *annotationView = (CustomPin *) [_mapita dequeueReusableAnnotationViewWithIdentifier:identifier];
        if (annotationView == nil) {
            annotationView = [[CustomPin alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
        } else {
            annotationView.annotation = annotation;
        }

        UIImage * image = [UIImage imageNamed:[NSString stringWithFormat:@"%@.png", [location elStatus]]];

        annotationView.enabled = YES;
        annotationView.canShowCallout = YES;
        annotationView.image = image;

        NSDictionary *temp = [[NSDictionary alloc] 
                              initWithObjects:[NSArray arrayWithObjects:annotationView, location, nil]
                              forKeys:[NSArray arrayWithObjects:@"view", …

在用户点击引脚,查看标注并点击显示详细视图控制器的显示按钮后,如何保持与MKAnnotation对象关联的数据？我想在详细视图控制器中显示与引脚相关的所有数据.

我有一个简单的MKAnnotation类,看起来像:

#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
@interface VoiceMemoryAnnotation : NSObject <MKAnnotation> {
    NSString * blobkey;
}
@property (nonatomic, retain) NSString * blobkey;

-(id)initWithBlobkey:(NSString *) key andCoordinate:(CLLocationCoordinate2D) c;
@end

我实现了回调"viewForAnnotation"

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id     <MKAnnotation>)annotation
{
    MKPinAnnotationView*singleAnnotationView = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:nil];


// PM: this pin will have a callout (i.e. dont' forget to override title function! Else exception thrown)
    singleAnnotationView.canShowCallout = YES;

// PM: add disclosure button
    UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

// PM: when user taps disclosure button, bring …

我现在使用Map Kit和Core Location,需要从邮政编码或城市/州获取位置信息.有什么办法吗？

我有以下文件:

annotation.h:

#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>

@interface annotation : NSObject <MKAnnotation>

@property(nonatomic, assign) CLLocationCoordinate2D coordinate;
@property(nonatomic, copy) NSString *title;
@property(nonatomic, copy) NSString *subtitle;


@end

annotation.m:

#import "annotation.h"

@implementation annotation

@synthesize coordinate, title, subtitle;

@end

在主代码中,它在NSURL其他地方找到了:

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
[spinner stopAnimating];

// json parsing
results = [NSJSONSerialization JSONObjectWithData:data options:nil error:nil];

NSMutableArray * locations = [[NSMutableArray alloc] init];
CLLocationCoordinate2D location;
annotation * myAnn;

NSArray *pins = mapView.annotations;

if ([pins count])
{
    [mapView removeAnnotations:pins];
}

/* loop through the array, …

如何将mapView集中在MKAnnotationView的calloutAccessory上？我知道如何将地图置于实际的annotationView中心,但我不知道如何将地图置于annotationView的calloutAccessory中心.有任何想法吗？

// This centers the map on the MKAnnotationView. However, I need to be able to
// center the map on the MKAnnotationView's calloutAccessory.
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    id<MKAnnotation> annotation = view.annotation;
    [self.mapView setCenterCoordinate:[annotation coordinate] animated:YES];
}

所以我正在开发一个项目,其中包括在地图周围放置注释的许多用途.屏幕上会出现注释(这是一个具有更大圆形范围的自定义图像),理想情况下,我希望用户为:

1. 如果它们在注释的范围内,则通知
2. 如果圆形针脚重叠超过25%,则不允许在另一个注释范围内放置另一个注释

我认为这是一个非常独特的问题,对于有人帮忙应该很有趣,所以玩得开心!谢谢大家!

我regionDidChangeAnimated用于我的mapView.我想检测用户缩放或拖动地图的时间.正在检测拖动,但我似乎无法检测用户缩放地图的时间.我试着用:

func mapView(mapView: MKMapView, regionWillChangeAnimated animated: Bool) {
    print("region will change")
}

但是当我缩放我的地图时,它不起作用.

完整代码:

var locationManager: CLLocationManager = CLLocationManager()
var startLocation: CLLocation!

@IBOutlet weak var mapView: MKMapView!

override func viewDidLoad() {
    super.viewDidLoad()

    //get current location
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.delegate = self
    locationManager.requestWhenInUseAuthorization()
    locationManager.startUpdatingLocation()

    self.mapView.showsUserLocation = true
    startLocation = nil

    let mapDragRecognizer = UIPanGestureRecognizer(target: self, action: "didDragMap:")
    mapDragRecognizer.delegate = self
    self.mapView.addGestureRecognizer(mapDragRecognizer)
    self.mapView.pitchEnabled = true
    self.mapView.showsBuildings = true

}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [CLLocation]) {
    let location = locations.last …

我有一张地图,在这张地图上我有自定义注释引脚.所有引脚都有相同的自定义图像 当我点击一个图钉时,我需要更改这个注释的图像.我之前使用的是谷歌地图:

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
    if marker.userData as? Int != nil {
        let marker_tag = marker.userData as! Int
        Datas.selectedMarkerIndex = marker_tag

        if let selectedMarker = mapView.selectedMarker {
            selectedMarker.icon = UIImage(named: "marker_gray")
        }
        mapView.selectedMarker = marker
        marker.icon = UIImage(named: "marker_red")                        
    }
    return true
}

这工作正常.但我不知道如何使用MapKit.我想改变选择的标记(图钉)图像.我怎样才能做到这一点？

我也尝试了这个,但没有工作 如何使用Swift在mapkit上更改非选定的注释图像

这是我的代码:

class CustomPointAnnotation: MKPointAnnotation {
    var pinImageName:String!
    var userData:Int!
}

extension MyView: MKMapViewDelegate {

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
    let …

我的项目是带有很多注释点的地图，由于有pickerView，用户可以查找特定的注释。一切正常，只是所有注释点的列表似乎随机显示。我想按字母顺序对注释进行排序。

这是我当前的工作代码：

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        return self.mapView.annotations[row].title ?? "No title"

    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        self.mapView.selectAnnotation(self.mapView.annotations[row], animated: true)
    }

我曾尝试实现这一点，但没有成功...

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

let sortedNames = self.mapView.annotations.sorted(by: {$0.title < $1.title})
        return sortedNames[row].title ?? "No title"

    }

我有这个错误：

无法转换类型为'String ??'的值 到预期的参数类型'UIContentSizeCategory'

任何提示将不胜感激。
