我想在我的MapView上集成气象雷达.请任何人帮忙完成这项任务.我做了很多谷歌搜索但没有成功.请检查这个图像,我想这样做.
解决方法
为实现这个任务我做了类似的事情：
在头文件(.h)中
@interface RDViewController : UIViewController{
UIImage *image ;
}
@property (strong,nonatomic) IBOutlet MKMapView *mapView;
@property (strong,nonatomic) IBOutlet UIActivityIndicatorView *activityIndicator;
@property (strong,nonatomic) IBOutlet UIImageView *imageView;
在.m文件中
@implementation RDViewController
@synthesize mapView;
@synthesize activityIndicator;
@synthesize imageView;
- (void)viewDidLoad
{
NSURL *url = [NSURL URLWithString:
@"http://radar.weather.gov/ridge/Conus/RadarImg/latest_radaronly.gif"];
MapOverlay * mapOverlay = [[MapOverlay alloc] initWithImageData:[NSData dataWithContentsOfURL:url] withLowerLeftCoordinate:CLLocationCoordinate2DMake(21.652538062803,-127.620375523875420) withUpperRightCoordinate:CLLocationCoordinate2DMake(50.406626367301044,-66.517937876818)];
//<LatLonBox><north>50.406626367301044</north><south>21.652538062803</south><east>-66.517937876818</east><west>-127.620375523875420</west></LatLonBox>
[mapView addOverlay:mapOverlay];
[super viewDidLoad];
// Do any additional setup after loading the view,typically from a nib.
}
- (void)viewDidUnload
{
[self setImageView:nil];
[self setMapView:nil];
[self setActivityIndicator:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return YES;
}
#pragma Mark - MKOverlayDelgateMethods
- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay {
MapOverlay *mapOverlay = overlay;
MapOverlayView *mapOverlayView = [[MapOverlayView alloc] initWithOverlay:mapOverlay];
return mapOverlayView;
}
