JBCountdownLabel

A UILabel subclass that displays a countdown

JBCountdownLabel is UILabel subclass that displays a countdown with a defined amount of seconds. So you can customise the label just like a native UILabel and add some cool actions:

• Customise the number of seconds on the countdown.
• You can show just the countdown or the countdown inside a sentence, you chose.
• Restart the countdown.
• Cancel the countdown.
• Change the amount of time on the countdown.

Installation

I recommend use CocoaPods to install JBCountdownLabel. Simply add the following line to your Podfile:

Podfile

pod 'JBCountdownLabel'

But you can also just drop JBCountdownLabel.m and JBCountdownLabel.h in your project.

Usage

Add the label to your view:

self.countdownLabel = [[JBCountdownLabel alloc] initWithFrame:CGRectMake(0, 50, 320, 46) format:@"Initiating ignition in %@" time:300 delegate:self];
self.countdownLabel.textColor = [UIColor colorWithRed:0.48 green:0.63 blue:0.07 alpha:1];
[self.view addSubview:self.countdownLabel];

You can change the countdown behaviour:

- (void)restartCountdown;
- (void)cancelCountdown;
- (void)setTime:(int)seconds;

There is an optional delegate callback to get notified when the countdown ended:

- (void)countdownFinnishInCountdown:(JBCountdownLabel *)countdown;
