Use of Swift or objective-c Iconfont fonts

iOS can use a single icon (svg,png) directly. You can also introduce font applications directly:

1: Add the Font file (. ttf) you downloaded from the Iconfont platform to the project;

Open the Info.plist file, add a new array type key, set the key name to Uiappfonts (Fonts provided by application), increase the font filename: "Iconfont.ttf"

2. Objective-c Use Iconfont font ：

UILabel * label =*iconfont = [Uifont fontwithname:@ "uxiconfont"  =@ "\u00003439 \u000035ad \u000035ae \u000035af \u000035eb \u000035ec"  ; [Self.view Addsubview:label];

In general, Iconfont is used for uiimage classes. You can write a Uiimage+iconfont classification to implement icon as a function of the image.
+ (uiimage*) Imagewithicon: (nsstring*) Iconcode Infont: (nsstring*) fontname size: (nsuinteger) Size color: (uicolor*) Color {cgsize imageSize=cgsizemake (size, size);    Uigraphicsbeginimagecontextwithoptions (ImageSize, NO, [[UIScreen mainscreen] scale]); UILabel*label = [[UILabel alloc] Initwithframe:cgrectmake (0,0, size, size)]; Label.font=[Uifont fontwithname:fontname size:size]; Label.text=Iconcode; if(color) {Label.textcolor=color;    } [Label.layer Renderincontext:uigraphicsgetcurrentcontext ()]; UIImage*retimage =Uigraphicsgetimagefromcurrentimagecontext (); returnRetimage;}

Here are two places to note:

• The Uifont is created using the font name, not the file name;
• The literal value is 8-bit Unicode character, we can open demo.html to find each icon corresponding to the HTML entity Unicode code, such as: "Store" corresponding to the HTML entity Unicode code: 0x3439 after conversion: \u00003439 is to replace 0x with \u middle with 0 filled with a full length of 8 characters

3. Swift 3.0 uses Iconfont fonts ：

Let label =  00, width:info.textsize!, height:info.textsize!  " Iconfont "  -  == \u{e60a} self.view.addSubview (label)    

In general, Iconfont is used for uiimage classes. You can write a taxonomy to inherit UIImage to implement icon as a picture function.
OpenclassFunc Iconbwithinfo (_ Info:iconinfo)uiimage{let Imagesize:cgsize= Cgsize (width:info.textsize!, height:info.textsize!) uigraphicsbeginimagecontextwithoptions (ImageSize,false, UIScreen.main.scale) let label= UILabel (Frame:cgrect (x:0Y:0, width:info.textsize!, height:info.textsize!)) Label.font= Uifont (Name:"Iconfont", Size: -) Label.textalignment=. Center Label.text=Info.textif(Info.textcolor! =Nil) {Label.textcolor=Info.textcolor} label.layer.render (inch: Uigraphicsgetcurrentcontext ()!) Let Image:uiimage= Uigraphicsgetimagefromcurrentimagecontext ()!returnImage}

Note: Swift uses Unicode encoding different from OC, Swift is \u{e60a} and OC is the \u0000e60a point to note.

Finally, add the Alibaba font vector icon Library
