adding html text to my UIWebView

I want to add text from my database to a UIWebView, but I have an error I can't deal with. in my .h: ``` #import <UIKit/UIKit.h> @interface readNotice : UIViewController { IBOutlet UILabel *message; IBOutlet UIWebView *body; } @property(nonatomic, retain)IBOutlet UILabel *message; @property(nonatomic, retain)IBOutlet UIWebView *body; -(void)getNoticeData:(NSString *)noticeID:(NSString *)noticeTitle; @end ``` In the .m: ``` @synthesize message,body; -(void)getNoticeData:(NSString *)noticeID:(NSString *)noticeTitle { //some taks not useful for this code NSString *bodyText = [dict objectForKey:@"introtext"]; [body loadHTMLString: bodyText]; } ``` The error I get: ``` No visible @interface for 'UIWebView' declares the selector 'loadHTMLString:' ``` why is this happening? Thank you in advance
