Ios 转换后，导航按钮将颜色更改为灰色

我可以使用“添加按钮”进行推送转换，但我还需要以编程方式进行。当我以编程方式执行此操作，然后返回时，“添加按钮”变为灰色。我对它进行了调试，可以看到_titleView中的_defaultattributes发生了变化。颜色值已更改。为什么会改变？如何预防呢？看起来很混乱

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    AddPalletViewController * addPalletViewController = [self addPalletViewControllerInstance];
    [addPalletViewController setEditMode:true];
    [addPalletViewController setEditModeRowValue: [[self.datasource objectAtIndex: indexPath.section] objectAtIndex: [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row+1]intValue]]];
    [[self navigationController] pushViewController: addPalletViewController animated:YES];
}

将此代码而不是您的代码放入

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
AddPalletViewController * addPalletViewController = [self addPalletViewControllerInstance];
[addPalletViewController setEditMode:true];
[addPalletViewController setEditModeRowValue: [[self.datasource objectAtIndex: indexPath.section] objectAtIndex: [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row+1]intValue]]];
[[self navigationController] pushViewController: addPalletViewController animated:YES];
//Will deselect your row...
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
