ios - Revert strikeThrough text to plain text after some operation is performed in TTTAttributedLabel -

i using code change color of label , set text strike through:

sliderlabel = [[tttattributedlabel alloc] initwithframe:cgrectmake(10, 260, 310, 30)];  sliderlabel.font = [uifont fontwithname:@"optima-bold" size:14]; [sliderlabel settag:112]; sliderlabel.linebreakmode = uilinebreakmodewordwrap; [sliderlabel setbackgroundcolor:[uicolor clearcolor]];  nsstring *sliderlabeltext = [nsstring stringwithformat:@"change to: in-progress (%d %%)",(int)slider.value]; [sliderlabel settext:sliderlabeltext afterinheritinglabelattributesandconfiguringwithblock:^ nsmutableattributedstring *(nsmutableattributedstring *mutableattributedstring) {     nsrange boldrange = [[mutableattributedstring string] rangeofstring:[nsstring stringwithformat:@"in-progress (%d %%)",(int)slider.value] options:nscaseinsensitivesearch];     nsrange strikerange = [[mutableattributedstring string] rangeofstring:sliderlabeltext options:nscaseinsensitivesearch];     uifont *boldsystemfont = [uifont fontwithname:@"optima-bold" size:14];     ctfontref font = ctfontcreatewithname((cfstringref)boldsystemfont.fontname, boldsystemfont.pointsize, null);     if (font) {         [mutableattributedstring addattribute:(nsstring *)kctforegroundcolorattributename value:(id)[uicolor colorwithred:8/255.0 green:156/255.0 blue:94/255.0 alpha:1.0].cgcolor range:boldrange];//34-139-34         [mutableattributedstring addattribute:ktttstrikeoutattributename value:[nsnumber numberwithbool:yes] range:strikerange];         cfrelease(font);     }      return mutableattributedstring; }]; [self.view addsubview:sliderlabel]; [sliderlabel release]; 

now want without strike through when perform operation click on button, passing [nsnumber numberwithbool:no] in addattribute:value:range doesnt work. suggestions?

try additions.
