iOS 4.2提供哪些字体?

What fonts do iPhone applications support ?

- (void)getAllFonts{
   NSArray *fontFamilies =[UIFont familyNames];

   for(int i =0; i <[fontFamilies count]; i++){
       NSString *fontFamily =[fontFamilies objectAtIndex:i];
       NSArray *fontNames =[UIFont fontNamesForFamilyName:[fontFamilies objectAtIndex:i]];
       NSLog(@"%@: %@", fontFamily, fontNames);
   }
}

@interface FontViewController (){
    NSArray* fontFamilies;
}

-(void)viewDidLoad{
    fontFamilies = [UIFont familyNames];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // The Magic :)    
    cell.textLabel.text = [fontFamilies objectAtIndex:indexPath.row];
    cell.textLabel.font = [UIFont fontWithName:[fontFamilies objectAtIndex:indexPath.row] size:12];

    return cell;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return fontFamilies.count;
}
