この値を別のクラスから出力しようとしましたが、選択したtabbar
インデックスが常に 0 として表示されます
なんで?どのタブが現在選択されているかを識別する他の方法はありますか?
私の2番目のクラスのtableviewcontroller
didselect
`メソッドでは、次の行を印刷しようとしています
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
sharedManager=[Mymanager sharedManager];
sharedManager.navigationBarTitle=[name objectAtIndex:indexPath.row];
NSLog(@"%d",self.tabBarController.selectedIndex);
}
しかし、それは常に0を示していますか?
別のタブに別のインデックスが必要ですか?
私の意図は、タブを識別してメソッドを呼び出すことです.4つの異なるメソッドを呼び出すように変更しますが、1つのオブジェクトを作成してメソッドを呼び出そうとすると、なぜ表示されないのですか?
私の APpdelegate.m
