Question

以下代码段显示在正确背景上的屏幕上，但文字不会滚动。

我错过了什么？

-(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];
}

Answer 1

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

Answer 2

我有同样的问题，我在这种模式下解决。在您的视图中添加一个类似OBGradientView的customView，并在此添加您的textView。在代码中添加查看您的ObGradientView并在其中添加textview。工作100％信任我
