我有一個自定義單元格中的地圖視圖。 我創建的單元格,委託這樣的:MKMapView在單元崩潰中
if (indexPath.section == 0) {
//mapview
static NSString *CellIdentifier = @"MapCell";
MapCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil];
cell = [topLevelObjects objectAtIndex:0];
}
// Map delegate
cell.mapView.delegate = self;
}
它工作正常,但有時crashlytics,出現以下日誌崩潰:

我不知道爲什麼崩潰有時會發生的一些用戶... Crashlytics說它發生在cellForRowAtIndexPath中。
感謝您的建議! – vburojevic
