FreeForm ViewController - iOS

Question

我已经在mainviewcontroller的顶部添加了另一个视图控制器(自由格式的viewController)，但不知何故，它并没有显示完整的尺寸。请看我的代码，这是下面和截图。

- (void)viewDidLoad
{
    [super viewDidLoad];
    firstSurveyViewController = [[FirstSurveyViewController alloc] initWithNibName:@"FirstSurveyViewController" bundle:[NSBundle mainBundle]];

    CGRect rect = [firstSurveyViewController.view frame];
    rect.origin.x = 10;
    rect.origin.y = 20;
    [firstSurveyViewController.view  setFrame:rect];
    [self.view addSubview:firstSurveyViewController.view];
}

Answer 1

尝试手动设置除原点外的宽度和高度。CGRect rect = [firstSurveyViewController.view frame];之后的rect的初始值是多少

似乎在这种情况下，firstSurveyViewController应该只是firstSurveyView，UIView的子类。
