由於未捕獲的異常“ NSInvalidArgumentException”而終止應用程序，原因：“-[MKUserLocation標記]：

Question

我只是比較兩個值，但有時應用程序崩潰。 如何處理。

NSString *  markerid = [_selectedCoordinate objectForKey:@"markerid"];
    for(CustomAnnotations *annotation in _mapView.annotations){
        if(annotation.tag == [markerid integerValue]){
            [_mapView selectAnnotation:annotation animated:NO];
            return;
        }
    }

Answer 1

地圖注釋也包含用戶位置注釋，請檢查[annotation class] != [MKUserLocation class]或[annotation class] == [CustomAnnoation class]然后獲取注釋的標簽

NSString *  markerid = [_selectedCoordinate objectForKey:@"markerid"];
for(CustomAnnotations *annotation in _mapView.annotations){
    if([annotation class] != [MKUserLocation class]) {
        if(annotation.tag == [markerid integerValue]) {
            [_mapView selectAnnotation:annotation animated:NO];
            return;
        }
    }
}
