## DEPRECATED IN FAVOR OF [Chronos-Swift](https://github.com/comyarzaheri/Chronos-Swift)
# Overview
Chronos is a collection of useful Grand Central Dispatch utilities. If you have any specific requests or ideas for new utilities, don't hesitate to create a new issue.
## Utilities
* **DispatchTimer** - A repeating timer that fires according to a static interval, e.g. "Fire every 5 seconds".
* **VariableTimer** - A repeating timer that allows you to vary the interval between firings, e.g. "Fire according to the function `interval = 2 * count`."
# Usage
### Quick Start
##### CocoaPods
Add the following to your Podfile:
```ruby
pod 'Chronos'
```
##### Carthage
Add the following to your Cartfile:
```ruby
github "comyarzaheri/Chronos" "master"
```
### Using a Dispatch Timer
```objective-c
#import
/** Create and start a timer */
CHRDispatchTimer timer = [CHRDispatchTimer timerWithInterval:1.0
executionBlock:^(CHRDispatchTimer *__weak timer, NSUInteger invocation) {
NSLog(@"%@", @"Execute repeating task here");
}];
[timer start:YES]; // Fire timer immediately
/** Pausing the timer */
[timer pause];
/** Permanently canceling the timer */
[timer cancel];
```
### Using a Variable Timer
```objective-c
#import
/** Create and start a timer */
CHRVariableTimer *timer = [CHRVariableTimer timerWithIntervalProvider:^NSTimeInterval(CHRVariableTimer *__weak timer, NSUInteger nextInvocation) {
return 2 * count; // Return interval according to function
} executionBlock:^(__weak id timer, NSUInteger invocation) {
NSLog(@"Execute repeating task here");
}];
[timer start:YES]; // Fire timer immediately
/** Pausing the timer */
[timer pause];
/** Permanently canceling the timer */
[timer cancel];
```
