   [theAlert show];

   UILabel *theTitle = [theAlert valueForKey:@"_titleLabel"];
   [theTitle setTextColor:[UIColor redColor]];

   UILabel *theBody = [theAlert valueForKey:@"_bodyTextLabel"];
   [theBody setTextColor:[UIColor blueColor]];

   UIImage *theImage = [UIImage imageNamed:@"Background.png"];    
   theImage = [theImage stretchableImageWithLeftCapWidth:16 topCapHeight:16];
   CGSize theSize = [theAlert frame].size;

   UIGraphicsBeginImageContext(theSize);    
   [theImage drawInRect:CGRectMake(0, 0, theSize.width, theSize.height)];    
   theImage = UIGraphicsGetImageFromCurrentImageContext();    
   UIGraphicsEndImageContext();

推荐答案

试试这个...

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlert View" message:@"hello" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Close",nil];

UIImage *alertImage = [UIImage imageNamed:@"plus.png"];

UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:alertImage];

backgroundImageView.frame = CGRectMake(0, 0, 282, 130);

backgroundImageView.contentMode = UIViewContentModeScaleToFill;

[alert addSubview:backgroundImageView];

[alert sendSubviewToBack:backgroundImageView]; 
[alert show];
[alert release];
