UITextView背景图片

Question

如何设置背景图像UITextView？

Answer 1

您可以UIImageView包含背景图像和UITextView兄弟姐妹,然后在Interface Builder中移动文本视图以重叠图像视图(或者如果以编程方式执行,则将它们添加到同一父视图中).您还需要确保文本视图不是不透明的,并为其提供0%不透明度背景.

Answer 2

UITextView *textView = [[UITextView alloc]initWithFrame: window.frame];
textView.text = @"text\n text\n text";
UIImageView *imgView = [[UIImageView alloc]initWithFrame: textView.frame];
imgView.image = [UIImage imageNamed: @"myImage.jpg"];
[textView addSubview: imgView];
[textView sendSubviewToBack: imgView];
[window addSubview: textView];

Answer 3

@durai:您的图像有一个高度限制,如果在向下滚动后出现空白背景,则会出现白色背景,然后您可以重复相同的图像.

这可能会有所帮助:

textView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed: @"Image.png"]];

Answer 4

只有一点澄清,当试用@oxigen的答案#9时,我发现这一行:

UIImageView *imgView = [[UIImageView alloc]initWithFrame: textView.frame];

是相对的textView.frame.因此x,y如果您希望它完全重叠,那么您的值和值必须为0,0这意味着您需要以下内容:

UIImageView *imgView = [[UIImageView alloc]initWithFrame:textView.bounds];

我找到了一个简单的方法来设置背景图像.

h文件

@interface FNTextView : UITextView

@end

m文件

...
- (void)drawRect:(CGRect)rect
{
    [self.bgImage drawInRect:rect];

    [super drawRect:rect];
}

{
    self.bgImage = [[UIImage imageNamed:@"textview_bg"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 4, 4, 4)];
}
