Question

这就是我的尝试，

 UITextView *_textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 10, 300, 10)];
    NSString *str = @"This is a test text view to check the auto increment of height of a text     view. This is only a test. The real data is something different.";
    _textView.text = str;


CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;//Here i am adjusting the textview

[self.view addSubview:_textView];



Basically after fitting the text into textview,scrolling is enable,but i cannot view the content inside the textview without scrolling the textview.I do want to initialize the UITextView frame size based on the text size,font name etc.

感谢任何解决方案。谢谢。

NSString *str = @"This is a test text view to check the auto increment of height of a text     view. This is only a test. The real data is something different.";
UIFont * myFont = [UIFont fontWithName:@"your font Name"size:12];//specify your font details here

//然后计算上述文本所需的高度。

CGSize textviewSize = [str sizeWithFont:myFont constrainedToSize:CGSizeMake(300, CGFLOAT_MAX) lineBreakMode:NSLineBreakByWordWrapping];

//根据您从上面获得的高度

初始化您的textview

UITextView *_textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 10, textviewSize.width, textviewSize.height)];
_textView.text = str;
[self.view addSubview:_textView];

并且您还要在textview中禁用滚动，然后参考。

正如William Jockusch在his answer here中所述：

您可以通过以下方法禁用几乎所有滚动进入你的UITextView子类：
- (void)scrollRectToVisible:(CGRect)rect animated:(BOOL)animated {
  // do nothing
}
我说“几乎”所有滚动的原因是，即使有上述情况，   它仍然接受用户滚动。虽然你可以禁用它们   将self.scrollEnabled设置为NO。

如果你只想禁用一些卷轴，那就做一个ivar，让我们打电话   它acceptScrolls，以确定是否要允许滚动或   不。然后你的scrollRectToVisible方法看起来像这样：
- (void)scrollRectToVisible:(CGRect)rect animated:(BOOL)animated {
   if (self.acceptScrolls)
     [super scrollRectToVisible: rect animated: animated];
}

根据可用的文本字体大小和字体名称初始化UITextView
