I have a UITextView *textView in cocos2d's CCLayer. The text is scrolling in both the horizontal and vertical directions. But, I need it to scroll and bounce only in vertically. How to stop the horizontal scrolling programmatically ?
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 ));
我应该怎么做才能停止水平滚动?

推荐答案
我不知道这是不是好的解决方案。但它为我工作。我在这里张贴,以便任何人可以纠正它。
I don't know whether it was the good solution. But it worked for me. I am posting here so that any one may correct it.
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];
它适用于我。它只向上和向下滚动,也上下弹回。
It worked for me. It scrolls only up and down and also bounces up and down.
谢谢。
