My font picker is now working fine,
all that is missing is 2 extra sections in the PickerView for font size and style (bold, italic and underlined).
I don't know how to approach changing these values.
This is my picker's code :
#import "ViewController.h"
#interface ViewController ()
{
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
fontNames = [NSMutableArray array];
for(NSString *familyName in [UIFont familyNames]) {
for(NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
[fontNames addObject:fontName];
}
}
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfComponentsInPickerView:
(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component
{
return fontNames.count;
}
- (NSString *)pickerView:(UIPickerView *)pickerView
titleForRow:(NSInteger)row
forComponent:(NSInteger)component
{
return [fontNames objectAtIndex:row];
}
- (UIView *)pickerView:(UIPickerView *)pickerView
viewForRow:(NSInteger)row
forComponent:(NSInteger)component
reusingView:(UIView *)view {
UILabel *pickerLabel = (UILabel *)view;
CGRect frame = CGRectMake(0.0, 0.0, 80, 32);
pickerLabel = [[UILabel alloc] initWithFrame:frame];
pickerLabel.backgroundColor = [UIColor clearColor];
pickerLabel.textAlignment = NSTextAlignmentLeft;
pickerLabel.text = [NSString stringWithFormat:#"%#",[fontNames objectAtIndex:row]];
pickerLabel.font = [UIFont fontWithName:[fontNames objectAtIndex:row] size:15];
return pickerLabel;
}
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row
inComponent:(NSInteger)component
{
_fontLabel.text = [fontNames objectAtIndex:row];
_fontLabel.font = [UIFont fontWithName:[fontNames objectAtIndex:row] size:15];
}
#end

You get the fonts using this loop:
NSMutableArray *fontNames = [NSMutableArray array];
for(NSString *familyName in [UIFont familyNames]) {
for(NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
[fontNames addObject:fontName];
}
}
How you present the picker depends on your UI layout. You might use an UITableView in an UIPopoverController (just google it, you'll find TONS of quite good tutorials) or an UIPickerView.
