Использование parse_str()
.
$str = 'pg_id=2&parent_id=2&document&video';
parse_str($str, $arr);
print_r($arr);
В iOS7 rectForMapRect:
и mapRectForRect:
устарели и теперь являются частью класса MKOverlayRenderer
. Я бы предпочел использовать методы MapView
mapRectThatFits: edgePadding:
. Вот пример кода:
MKMapRect visibleRect = self.mapView.visibleMapRect;
UIEdgeInsets insets = UIEdgeInsetsMake(50, 50, 50, 50);
MKMapRect biggerRect = [self.mapView mapRectThatFits:visibleRect edgePadding:insets];
последний Swift для 2017 ...
func updateMap() {
mkMap.removeAnnotations(mkMap.annotations)
mkMap.addAnnotations(yourAnnotationsArray)
var union = MKMapRectNull
for p in yourAnnotationsArray {
// make a small, say, 50meter square for each
let pReg = MKCoordinateRegionMakeWithDistance( pa.coordinate, 50, 50 )
// convert it to a MKMapRect
let r = mkMapRect(forMKCoordinateRegion: pReg)
// union all of those
union = MKMapRectUnion(union, r)
// probably want to turn on the "sign" for each
mkMap.selectAnnotation(pa, animated: false)
}
// expand the union, using the new #edgePadding call. T,L,B,R
let f = mkMap.mapRectThatFits(union, edgePadding: UIEdgeInsetsMake(70, 0, 10, 35))
// NOTE you want the TOP padding much bigger than the BOTTOM padding
// because the pins/signs are actually very tall
mkMap.setVisibleMapRect(f, animated: false)
}
Как насчет преобразования visibleMapRect
в CGRect
с rectForMapRect:
, получая новый CGRect
с CGRectInset
, а затем преобразовывая его обратно в MKMapRect
с mapRectForRect:
?
