中的MKMapView

Question

在我的應用程序使用UIActivityIndi​​cator我下載KML文件，並顯示其數據在map.How顯示一個活動的指標，同時下載數據（竊聽初始化下載過程中的UIButton後停止下載完成時和銷填充圖）？

Answer 1

您只需啓動活動的指標裝載在初始部分一樣喜歡在全視圖只圖有那麼

-(void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    //I have use drag and drop method for activity indicator and map it with outlet without fail and then implement it. 
    activityIndicator.hidden = TRUE; 
} 

-(void)viewWillAppear:(BOOL)animated 
{ 
    [super viewWillAppear:animated]; 
    activityIndicator.hidden = FALSE; 
    [activityIndicator startAnimating]; 
} 

下面的方法將後調用加載地圖所以，

- (void)mapViewDidFinishLoadingMap:(MKMapView *)mapView 
{ 
     [activityIndicator stopAnimating]; 
     activityIndicator.hidden = TRUE; 
} 

我認爲它會爲你
