In viewDidLoad
在视图中DidLoad
textView.backgroundColor = [UIColor clearColor];
UIImageView *imageView = [[[UIImageView alloc] initWithFrame:textView.frame] autorelease];
imageView.image = [UIImage imageNamed:@"myBackgroundImage.png"];
[self.view addSubview:imageView];
[self.view bringSubviewToFront:textView];

Try to make a new class. (Did not test the code, just typed it on the forum, try to use the code otherwise: use the concept)
尝试创建一个新类。（没有测试代码，只是在论坛上输入，否则尝试使用代码：使用概念）
@interface TextViewWithImage : UIView {
UITextView *textView;
UIImageView *imageView;
}
@property (retain, readonly) UITextView *textView;
@property (retain, readonly) UIImageView *imageView;
@implementation TextViewWithImage
- (id) init {
if (self = [super init]) {
[self setupContentViews];
}
return self;
}
- (id) initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
[self setupContentViews];
}
return self;
}
- (void) setupContentViews {
textView = [[UITextView alloc] init];
imageView = [[UIImageView alloc] init];
textView.frame = self.frame;
imageView.frame = self.frame;
textView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
imageView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
}
- (void) dealloc {
[textView release];
[imageView release];
[super dealloc];
}
@end

UIViews (of which UITextView is a subclass) have a property called backgroundColor.
UIViews（其中 UITextView 是其子类）有一个名为 backgroundColor 的属性。
@property(nonatomic, copy) UIColor *backgroundColor
Try calling [textView setBackgroundColor:[UIColor clearColor]] on the TextView and putting an image view behind it.
尝试在 TextView 上调用 [textView setBackgroundColor:[UIColor clearColor]] 并将图像视图放在其后面。
