iPhone: Custom Fonts Using Zynga's FontLabel Class

November 30th, 2009

Using custom fonts is not the most straight forward thing on the iPhone. Luckily good people at Zynga developed an easy to use FontLabel class. Download it here. Add the files to your project.

Step 1. Import the FontLabel header:

#import "FontLabel.h"

Step 2. Create a label.

//note the name of my font file is 'Rage italic.tty'
FontLabel *label = [[FontLabel alloc] initWithFrame:CGRectMake(10, 10, 210, 110) fontName:@"Rage Italic" pointSize:30.0f];

//set the color
label.textColor = [UIColor colorWithRed:0.254 green:0.216 blue:0.078 alpha:1];

//set the text
label.text = @"Denis you're a handsome man!";

//skip the background. make it transparent
label.backgroundColor = nil;
label.opaque = NO;

label.lineBreakMode = UILineBreakModeTailTruncation;

//dynamic number of lines
label.numberOfLines = 0;

//text alignment
label.textAlignment = UITextAlignmentCenter;

//add to where you need it
[myView addSubview: label];

//and release it
[label release];

iPhone: Rotate an UIImageView

November 30th, 2009

Couldn’t be easier. Just make sure that degrees are in radians.

imgView.transform = CGAffineTransformMakeRotation (degrees);

You can spice it up with animation:

[UIView beginAnimations:@"rotateAni" context:nil];
//set the duration to 5 seconds
[UIView setAnimationDuration:5.0];
imgView.transform = CGAffineTransformMakeRotation (degrees);
[UIView commitAnimations];
