IOS Button Settings AttributeString Adaptive dimension experience in different states

Describe the following scenario: button displays different title styles in different states

[uifont Span class= "S3" >systemfontofsize:18.0f Weight:uifontweightregular]  color is   [uicolor blackcolor

Select under Font is[uifont systemfontofsize:18.0f weight:uifontweightmedium] color is [uicolor Graycolor]

Start with this setting:

nsattributedstring *normal_title = [[Nsattributedstring alloc] initwithstring:@"Reviews 20320323"Attributes:@{nsfontattributename:[uifont systemfontofsize:18.0fWeight:uifontweightregular],nsforegroundcolorattributename:unselect_color}]; Nsattributedstring*select_title = [[Nsattributedstring alloc] initwithstring:@"Reviews 20320323"Attributes:@{nsfontattributename:[uifont systemfontofsize:18.0fWeight:uifontweightmedium],nsforegroundcolorattributename:select_color}]; UIButton*button1 =[UIButton Buttonwithtype:uibuttontypecustom]; Button1.backgroundcolor=[Uicolor Redcolor]; Button1.frame= CGRectMake (10.0,400.0,100.0,20.0f);    [button1 Setattributedtitle:normal_title Forstate:uicontrolstatenormal];    [button1 Setattributedtitle:select_title forstate:uicontrolstateselected];    [Button1 SizeToFit]; [Button1 addtarget:self Action: @selector (Showselect:) forcontrolevents:uicontroleventtouchupinside];-(Ibaction) Showselect: (ID) sender{if([Sender Iskindofclass:[uibuttonclass]]) {UIButton*button = (UIButton *) sender; Button.selected= !button.selected; [Button SizeToFit];}
