oc 解决状态栏干扰...

#pragma mark - 去除状态栏干扰的方法
- (void)viewDidLoad {
    [super viewDidLoad];
    if (_tableView.style == UITableViewStylePlain) {
        UIEdgeInsets contentInset = _tableView.contentInset;
        contentInset.top = 20;
        [_tableView setContentInset:contentInset];

        UIView *barBackground = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 20)];
        barBackground.backgroundColor = [UIColor colorWithWhite:1 alpha:0.9];
        [self.view addSubview:barBackground];
    }
    // Do any additional setup after loading the view, typically from a nib.
}

UIEdgeInsets是一个结构体,上下左右四个方向都可以让出位置.
