从XIB中提取UI项目?

在对文档进行了一番搜索之后,我决定使用“viewWithTag”从loadNibName返回的主根视图中提取子视图:owner:options:to start with我有点困惑,因为我假设loadNibName:owner:options会在事实上,它似乎返回根视图(或根视图)。谁能证实我做得对,我只是好奇,是否还有其他(也许更好)的方法来提取和设置一个文件中的项目?

- (void)loadView {
    NSLog(@"HYBRID UI: %s", __PRETTY_FUNCTION__);
    NSArray *nibArchive = [[NSBundle mainBundle] loadNibNamed:@"Interface" owner:self options:nil];
    NSLog(@"SIZE: %d ARRAY: %@", [nibArchive count], nibArchive);

    // UIView
    UIView *nibView = [nibArchive lastObject];
    [nibView setFrame:[[UIScreen mainScreen] applicationFrame]];
    NSLog(@"FRAME: %@", NSStringFromCGRect([nibView frame]));
    [self setView: nibView];

    // UILabel
    UILabel *nibLabel = (UILabel *)[nibView viewWithTag:101];
    [nibLabel setText:@"FRINGE"];
    [nibLabel setTextColor:[UIColor whiteColor]];

    // UIImageView
    UIImageView *nibImageView = (UIImageView *)[nibView viewWithTag:102];
    [nibImageView setBackgroundColor:[UIColor whiteColor]];
}
