Cocoa touch 如何以编程方式停止水平滚动？

我在cocos2d的CCLayer中有一个UITextView*textView。文本在水平和垂直方向上滚动。但是，我需要它只在垂直方向滚动和反弹。 如何以编程方式停止水平滚动

   UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(100,200, windowSize.height/2,windowSize.width/2)];
  textView.backgroundColor = [UIColor clearColor];
textView.text = @"I am First enemy I am First enemy I am First enemy I am First  enemy I am First enemy I am First enemy I am First enemy I am First enemy";
[textView setEditable:NO]; 
textView.font = [UIFont fontWithName:@"Helvetica" size:24.0f];
CGPoint location = CGPointMake(200, 160);
textView.showsHorizontalScrollIndicator = NO;
   //textView.bounces = NO;
//textView.alwaysBounceVertical = YES;

    textView.center = location;
    textView.transform = CGAffineTransformMakeRotation(CC_DEGREES_TO_RADIANS( 90.0f ));  

如何停止水平滚动

谢谢。

我不知道这是否是一个好的解决方案。但这对我很管用。我张贴在这里，以便任何人都可以纠正它

    textView = [[UITextView alloc] initWithFrame:CGRectMake(100,200,200 ,200)];
    textView.backgroundColor = [UIColor clearColor];
    NSLog(@"description: %@", enemyDescription);
    textView.text = enemyDescription;
    [textView setEditable:NO]; 
    textView.font = [UIFont fontWithName:@"Helvetica" size:14.0f];
    CGPoint location = CGPointMake(200, 160);
    textView.showsHorizontalScrollIndicator = NO;
    textView.alwaysBounceVertical = YES;

    textView.transform = CGAffineTransformMakeRotation(CC_DEGREES_TO_RADIANS( 90.0f ));

    [[[CCDirector sharedDirector]openGLView]addSubview:textView];   

这对我有用。它只会上下滚动，也会上下反弹

谢谢。

所以您只硬编码较小的字体？我想您可以计算textView的contentView边界并调整字体大小，使其适合textView
