### 1.编写初衷 ###

由于IOS中字体都是英文名称，根据设计去去选择字体的时候，经常只能看到字体名字，不能确定字体名字对应的字体是什么样子，所以写了一个demo。用于查看IOS系统中目前所有的可用字体，并展示到界面中，点击想要字体的按钮就弹出字体名字。

### 2.获取所有字体名字 ###

-(void)initFontArray{
      fontNameArray=[[NSMutableArray alloc] init];
      NSArray *familyNames = [[NSArray alloc] initWithArray:[UIFont familyNames]];
      NSInteger indFamily, indFont;
      for(indFamily=0;indFamily<[familyNames count];++indFamily)
        {
           
            NSArray* fontNames =[[NSArray alloc]initWithArray:[UIFont fontNamesForFamilyName:[familyNames objectAtIndex:indFamily]]];
            for(indFont=0; indFont<[fontNames count]; ++indFont)
            {
                [fontNameArray addObject:[fontNames objectAtIndex:indFont]];
            }
            
        }
    
    }

###    3.展示到界面上 ###

-(void)initScrollView{
        
        
        UIScrollView *btnScrollView=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
        [btnScrollView setBackgroundColor:[UIColor whiteColor]];
        CGFloat jianGe=20;
        CGFloat btnToLeft=40;
        CGFloat btnHeight=30;
        CGFloat btnToTop=40;
        chinese=@"测试字体";
        
        for (NSInteger index=0; index<[fontNameArray count]; index++) {
            
            NSString *fontName=[fontNameArray objectAtIndex:index];
            UIButton *btn=[[UIButton alloc] initWithFrame:CGRectMake(btnToLeft, btnToTop, self.view.frame.size.width-2*btnToLeft, btnHeight)];
            NSString *title=[[NSString alloc] initWithFormat:@"%@%ld",chinese,index];
            [btn setTitle:title forState:UIControlStateNormal];
            [btn addTarget:self action:@selector(titleBtnPress:) forControlEvents:UIControlEventTouchUpInside];
            btn.titleLabel.textAlignment=NSTextAlignmentCenter;
            [btn.layer setCornerRadius:4.0]; //设置矩形四个圆角半径
            [btn.layer setBorderWidth:1.0];
            btn.tag=index;
            [btn.layer setBorderColor:[UIColor blueColor].CGColor];
            [btn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
            [btn.titleLabel setFont:[UIFont fontWithName:fontName size:20]];
            [btnScrollView addSubview:btn];
            btnToTop=btnToTop+btnHeight+jianGe;
        }
        [btnScrollView setContentSize:CGSizeMake(self.view.frame.size.width, btnToTop)];
        [self.view addSubview:btnScrollView];
    }
