向MKMapView添加子視圖（不是覆蓋圖）

Question

我想在iOS地圖視圖的點擊點處添加一個小的子視圖，以便在滾動和縮放地圖視圖時添加子視圖時也可以縮放和滾動。任何幫助？我試過的代碼如下：

- (void)viewDidLoad 
{ 
    UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(foundTap:)]; 
    tapRecognizer.numberOfTapsRequired = 1; 
    tapRecognizer.numberOfTouchesRequired = 1; 
    [self.myMapView addGestureRecognizer:tapRecognizer]; 
} 

- (IBAction)foundTap:(UITapGestureRecognizer *)recognizer 
{ 
    CGPoint point = [recognizer locationInView:self.myMapView]; 
    dotimage = [[UIView alloc]initWithFrame:CGRectMake(point.x,point.y , 10, 10)]; 
    dotimage.backgroundColor = [UIColor redColor]; 
    [self.myMapView addSubview:dotimage]; 
} 

視圖dotimage未移動並且滾動地圖視圖。

你的做法是錯誤的，你不能認爲添加在地圖子視圖縮放，你必須在自來水中添加自定義針，自定義針應該看起來像要添加您的看法..

你可以試試在你下面

- (void)viewDidLoad 
{ 
     UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomView:)]; 
     [recognizer setNumberOfTapsRequired:1]; 
     [map addGestureRecognizer:recognizer]; 
     [recognizer release]; 
} 

- (void)addCustomView:(UITapGestureRecognizer*)recognizer 
{ 
    CGPoint tappedPoint = [recognizer locationInView:map]; 
    //Get the coordinate of the map where you tapped 
    CLLocationCoordinate2D coord= [map convertPoint:tappedPoint toCoordinateFromView:map]; 

    //Add Annotation 
    /* Create a custom annotation class which takes coordinate */ 
    CustomAnnotation *ann=[[CustomAnnotation alloc] initWithCoord:coord]; 
    [map addAnnotation:ann]; 

} 

然後代碼map delegate功能

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{ 
    if([annotation isKindOfClass:[CustomAnnotation class]]) 
    { 
     //Do your annotation initializations 

     // Then return a custom image that looks like your view like below 
     annotationView.image=[UIImage imageNamed:@"customview.png"]; 
    } 
} 

一切順利..
