iOS reason: 'Invalid Region <center:+113.15000000, +23.02000000 span:+1.25000000, +1.25000000>'

原因：latitude 113，已經超過範圍是超出範圍了，加上範圍判斷, 如下所示：

 if ( (theRegion.center.latitude >= -90) && (theRegion.center.latitude <=90) && (theRegion.center.longitude >= -180) && (theRegion.center.longitude <=180) ){

    [mapView setRegion:[mapView regionThatFits:theRegion] animated:YES];

}else{

   NSLog(@"invilid region");

}
