Rich Text controls

A variety of rich text control on the network total feel and specific items are not too, so I wrote a rich text control, is written with Coretext. Now open up for everyone to learn from and use. I have written some basic functions that you can easily add to the functionality you want to implement.

You can arbitrarily use, modify, extend this control, please do not delete the author information

When you use it, don't forget to introduce the Coretext library.

Demo effect

Call the method code as follows:

1. Display pictures

-(void) showimage{uifont *font = [Uifont systemfontofsize:17];    Sjrichtextview *richtextview = [[Sjrichtextview alloc] Initwithframe:cgrectmake (100, 50, 200, 80)];    Richtextview.textmaxwidth = 150;    Richtextview.textcolor = [Uicolor blackcolor];    Richtextview.font = font;    NSString *imagetext = [Sjrichtextinterpreter imgtextwithurl:@ "Demoimage.png" Size:cgsizemake (50, 50)];    Richtextview.text = [NSString stringwithformat:@ "Photo Demo:%@", Imagetext]; [Self.view Addsubview:richtextview];}

2. Display text (supports calculating height by number of rows and calculating total text height)

-  (void) showtext{    uifont *font = [uifont systemfontofsize:17];     SJRichTextView *richTextView = [[SJRichTextView alloc]  Initwithframe:cgrectmake (100, 150, 200, 71)];    richtextview.textmaxwidth  = 150;    richTextView.textColor = [UIColor blackColor];     richtextview.font = font;    richtextview.text = @ " Text presentation text presentation text presentation text presentation text presentation text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo text Demo;     [self.view addsubview:richtextview];        cgfloat  minheight = [richtextview heightforlinenumber:4];    nslog (@ " The height of four lines of text is:%f ",  minheight);         cgfloat maxheight =  [richtextview heightformaxLine];    nslog (@ "Total text height is:%f",  maxheight);} 

3. Display expression

-  (void) showemotion{    uifont *font = [uifont systemfontofsize :17];    sjrichtextview *richtextview = [[sjrichtextview alloc]  Initwithframe:cgrectmake (100, 300, 200, 80)];    richtextview.textmaxwidth  = 150;    richTextView.textColor = [UIColor redColor];     richtextview.font = font;    richtextview.emotioniconwidth  = font.lineHeight;    richTextView.emotionIconHeight =  font.lineheight;    richtextview.richtextviewdatasource = self;     richtextview.text = @ "Expression presentation: [Aesthetic]";     [self.view addsubview: Richtextview];} #pragma  mark SJRichTextViewDataSource-  (nsstring *) imagepathwithemotionstring: (nsstring  *) emotionstring{    if  ([emotionstring isequaltostring:@, "aesthetic"])  {         nsstring *imagepath = [nsstring stringwithformat:@ "%@/%@",  [NSBundle  mainbundle].resourcepath, @ "Demoimage.png"];        return  imagepath;    }    return nil;}

4. Show Link

-  (void) showurl{    uifont *font = [uifont systemfontofsize:15];     SJRichTextView *richTextView = [[SJRichTextView alloc]  Initwithframe:cgrectmake (50, 400, 300, 80)];    richtextview.textmaxwidth  = 300;    richTextView.textColor = [UIColor redColor];     richtextview.font = font;    richtextview.richtextviewdelete  = self;    NSString *urlText = [SJRichTextInterpreter  urltextwithurl:@ "http://www.baidu.com"  displaystring:@ "Baidu"];    richtextview.text  = [nsstring stringwithformat:@ "The text on the right is a link, point to see:%@",  urltext];    [ Self.view addsubview:richtextview];} #pragma  mark SJRichTextViewDelegate-  (void) Touchurl: (nsstring *) URL{   &NBSp nsurl *gourl = [nsurl urlwithstring:url];    if  (goURL ==  nil)  {        return;    }     [[uiapplication sharedapplication] openurl:gourl];}
