1.編寫初衷

     由於IOS中字型都是英文名稱，根據設計去去選擇字型的時候，經常只能看到字型名字，不能確定字型名字對應的字型是什麼樣子，所以寫了一個demo。用於檢視IOS系統中目前所有的可用字型，並展示到介面中，點選想要字型的按鈕就彈出字型名字。       

2.獲取所有字型名字

-(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.展示到介面上

-(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;

    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]; //設定矩形四個圓角半徑
        [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];
}
