ios - UITextView不滚动，需要帮助

以下代码段显示在屏幕上正确的背景顶部，但是文本不会滚动。

我想念什么？

-(void) viewWillAppear:(BOOL)animated {

    UITextView *scrollableText = [[UITextView alloc] initWithFrame:CGRectMake(20, 20, 300, 800)];
    [scrollableText setOpaque:TRUE];
    [scrollableText setBackgroundColor:[UIColor clearColor]];

    [scrollableText setEditable:NO];
    [scrollableText setText:@"some really really long text"];

    [scrollableText setScrollEnabled:YES];

    UIImage *backgroundImage = [[UIImage alloc] initWithCGImage:[UIImage imageNamed:@"about_bg.png"].CGImage];
    UIImageView *backgroundView = [[UIImageView alloc] initWithImage:backgroundImage];

    [backgroundView addSubview:scrollableText];

    [[self view] addSubview:backgroundView];
}

最佳答案

除了[textview setUserInteractionEnabled:YES]之外，还可以尝试textView.userInteractionEnabled = YES;或setScrollEnabled。
