ios - UITextView 中带有新行的不正确排除路径

Question

当 textView 有换行符时，我遇到了 exclusionPaths 的问题:

这是我的代码:

- (void)viewDidLoad
{
  [super viewDidLoad];
  UIView *view = [[UIView alloc] init];
  UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 333, 360, 480)];
  view.frame = CGRectMake(50, 0, 50, 50);
  view.backgroundColor = [UIColor blackColor];
  NSLog(@"%@", NSStringFromCGRect(view.frame));
  [textView addSubview:view];

  CGRect relativeRect = [textView convertRect:view.bounds fromView:view];

  UIBezierPath *bezierPath = [UIBezierPath bezierPathWithRect:relativeRect];
  textView.text = @"asddsaadasddsasdasdjsdhfjkdhkjdhfgjkldhsgfjlk\n\nhfdsgjklhdfsljkghdklfjgshdgjklfshdfgjklhfglkjdshjklgfdshjklgdfshkljfdsghfjkldghlkjfdghskljgdfhslkjgdfshjklgfdshjkgfdshlkjgdfhskljdgfhsjklgdhsjklfgdshjkglfdshjklgfdshlkjfgdhjklgdfshjdfkslghkjfdlsghjkldsfghjkhdfsgkjlhjgkldfshgdflksjhfdksgjhdfkjlgshfkljdshgjkdfhskjglhdfsjkghdfkjglhdsfkjghkljdfhgkjlhdsfkjlghjkldsfghjklhgsfdjklhgsdfkjlghdsfklgfdhsklg";
  textView.textContainer.exclusionPaths = @[bezierPath];
  [self.view addSubview:textView];

}

结果如下:

问题是新行字符使排除路径比它们应该的更大。此处也描述了该问题:Newlines in iOS 7 UITextView breaking Text Kit exclusion zone wrapping ，但它显示了如何在使用 Interface Builder 创建 UITextView 时修复此 iOS 7 错误。我将如何以编程方式解决这个问题？谢谢!

所以要禁用的获胜属性是“scrollEnabled”:

textView.editable = NO
textView.scrollEnabled = NO

上面的代码修复了我的 exclusionPaths 问题
