您在屏幕上有註釋。該註釋是緯度和寬度值。

NSArray *data = [root objectForKey:@"data"]; 
    for (NSArray *row in data) { 
    NSNumber * latitude = [[row objectAtIndex:22]objectAtIndex:1]; 
    NSNumber * longitude = [[row objectAtIndex:22]objectAtIndex:2]; 
    NSString * crimeDescription = [row objectAtIndex:18]; 
    NSString * address = [row objectAtIndex:14]; 

    CLLocationCoordinate2D coordinate; 
    coordinate.latitude = latitude.doubleValue; 
    coordinate.longitude = longitude.doubleValue; 
    MyLocation *annotation = [[MyLocation alloc] initWithName:crimeDescription address:address coordinate:coordinate] ; 
    [_mapView addAnnotation:annotation]; 
}
