问题描述: 在tableview 的cell中添加CellVC.view ,运行在模拟器iPhone 5sUI正常. 在换个6s模拟器后,UI不正常了.

测试代码如下:

UITableViewCell*cell  = [tableViewdequeueReusableCellWithIdentifier:@"identifier"];

    if(!cell) {

      cell = [[UITableViewCell alloc]   initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"identifier"];

        [cellsetSelectionStyle:UITableViewCellSelectionStyleNone];

    }

    if(!_vc) {

        _vc = [[CellVC alloc] init];

    }

    NSLog(@"befire====%@",_vc.view);

    [cell.contentView addSubview:_vc.view];

    NSLog(@"after====%@",_vc.view);

    returncell;

cellVC中,打印self.view.frame时,

-(void)viewDidLayoutSubviews {

    NSLog(@"self ====%@",self.view);

}

打印三者frame.

测试5s ,7p,6s,8,其中 6s,8 的frame.size.width会莫名编程430.
