是的，你可以。

您必须像往常一样创建一个 UITextView 并将图像添加为 UIImageView 中的子视图。

yourTextView = [[UITextView alloc] init];
yourTextView.frame = CGRectMake(0, 10, self.view.frame.size.width, self.view.frame.size.height);
yourTextView.font = [UIFont fontWithName:@"HelveticaNeue-Light" size:20];

yourTextView.text = @"The year was 1572. Pratap Singh had just become the Maharana of Mewar and he had not been back in Chittor since 1567. His old fort and his home beckoned to him. The pain of his father's death, and the fact that his father had not been able to see Chittor again, troubled the young Maharana deeply. But he was not the only one troubled at this time. Akbar had control of Chittor but not the kingdom of Mewar. So long as the people of Mewar swore by their Maharana, Akbar could not realize his ambition of being the Jahanpanah of Hindustan.";
[self.view addSubview:yourTextView];

yourImageView = [[UIImageView alloc] init];
yourImageView.frame = CGRectMake(100, 100, self.view.frame.size.width-100, (self.view.frame.size.width-100)*1.5 );

yourImageView.image = [UIImage imageNamed:@"imageOfAnOldSamurai.png"];
[yourTextView addSubview:yourImageView];

要使 textview 内的文本环绕图像，请使用 exclusionPaths，这是一个 UIBezierPath 和来自 imageview 的框架。

- (void)viewDidLayoutSubviews {
    UIBezierPath * exclusionPath = [UIBezierPath bezierPathWithRect:yourImageView.frame];
    yourTextView.textContainer.exclusionPaths  = @[exclusionPath];
}

上面的代码为我创建了这个结果：
