Please refer to the documentation of UITextField and you will find the following:
请参考 UITextField 的文档，你会发现以下内容：
The default value for this property is UITextBorderStyleNone. If the value is set to the UITextBorderStyleRoundedRect style, the custom background image associated with the text field is ignored.
此属性的默认值为 UITextBorderStyleNone。如果该值设置为 UITextBorderStyleRoundedRect 样式，则与文本字段关联的自定义背景图像将被忽略。
In Interface Builder, just below the place where you set the background image, there should be an option to select a border style, by default it is selected to RoundedRect, select another style and you can immediately see the background image.
在Interface Builder中，在你设置背景图片的地方下方，应该有一个选择边框样式的选项，默认选择的是RoundedRect，选择另一种样式可以立即看到背景图片。

First one, add the image to your Assets.xcassetswith the name you want, like myImage. In your textfield, you can set it with:
首先，将图像添加到您Assets.xcassets想要的名称中，例如myImage. 在您的文本字段中，您可以设置它：
myTextField.background = UIImage(named: "myImage")

myTextField.layer.borderWidth = 0

CGRect frame1 = CGRectMake(30, 130,160, 30);
textField = [[UITextField alloc] initWithFrame:frame1];
textField.borderStyle =UITextBorderStyleNone;
textField.background=[UIImage imageNamed:@"textFieldImage.png"];

To add a background image to views that have no background image property, you will need to do some trickery. You will need to create a UIImageView and then add the UITextView as a subview. Make sure the UITextView background color is set to clear as well. For example:
要将背景图像添加到没有背景图像属性的视图中，您需要做一些技巧。您需要创建一个 UIImageView，然后将 UITextView 添加为子视图。确保 UITextView 背景颜色也设置为清除。例如：
UIImageView *imageView = [[UIImageView alloc] initWithimage:myImage];
[self.view addSubview:imageView];
[imageView addSubview:myTextView];
