編輯模式

1. 移除




獲得delete按鈕控制

-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
    return YES;
}
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
    NSLog(@"%d",indexPath.row);
}



2.  移除指定物件並回寫我的最愛



-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
    NSLog(@"%d",indexPath.row);
    [tbView beginUpdates];
    //移除畫面上某筆資料
    [tbView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
    //移除陣列中資料，否則資料與畫面對不上會產生錯誤
    [items removeObjectAtIndex:indexPath.row];
    //更新畫面
    [tbView endUpdates];
    
    [[NSUserDefaults standardUserDefaults] setObject:items forKey:@"FAVORITE"];
    [[NSUserDefaults standardUserDefaults] synchronize];
    
    
}

• 指定某列不給控制

-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
    
    if(indexPath ==0){
        return NO;
    }else{
        return YES;
    }
}

• 調整順序

-(BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath{
    return YES;
}
-(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{
    //要移除前先指定給暫存
    NSDictionary *entry = items[sourceIndexPath.row];
    //移除這個位置原本的item
    [items removeObjectAtIndex:sourceIndexPath.row];
    //將暫存插入原本位置
    [items insertObject:entry atIndex:destinationIndexPath.row];
    //更新我的最愛
    [[NSUserDefaults standardUserDefaults] setObject:items forKey:@"FAVORITE"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}
