You want to add pod 'Crontab-IOS', '~> 1.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'Crontab-IOS', '~> 1.0'

A light-weight library to execute Objective-C codes only once in app life with a crontab like way. Execute code/blocks only for the first time the app runs, for example.

Installation

We recommend you to install this project using CocoaPods:

Podfile

platform :ios, '5.0'
pod "Crontab-IOS"

Usage

cronRule : times day

NSString * cronRule = @"1 1";
[CronTabCenter addCronJob:cronRule forBlock:^{
        NSLog(@"1 1 executed");
    }];

The cronRule is kind of NSString class , and separated By a Space.
The first number represents the times of the app launch today.
The second number represents the day of the app launch.
@"1 1" means the first day's first launch，just like for the first time to launch。Use this option, for example, to run a welcome dialog or create a initial database.
@"1 *" means the every one day's first launch。Use this option, for example,to ask to buy the PRO version every day.
@"1 */7" means the every seven day's first launch。Use this option, for example,to ask to rate your app every 7 days.

cronRule : totalTimes

NSString * cronRule = @"1";
[CronTabCenter addCronJob:cronRule forBlock:^{
        NSLog(@"1 executed");
    }];

The cronRule is kind of NSString class , and separated By a Space.
The cronRule number represents the total times of the app launch.
@"1" means the first day's first launch，just like the @"1 1".
@"*" means the first day's first launch，just like the @"* *".

Example

This is just a example to show the usage of crontab-ios


    [CronTabCenter addCronJob:@"1 1" forBlock:^{
        NSLog(@"1 1 executed");
    }];

    [CronTabCenter  addCronJob:@"2 1" forBlock:^{
        NSLog(@"2 1 executed");
    }];

    [CronTabCenter  addCronJob:@"1 *" forBlock:^{
        NSLog(@"1 * executed");
    }];

    [CronTabCenter addCronJob:@"2 *" forBlock:^{
        NSLog(@"2 * executed");
    } elseBlock:^{
        NSLog(@"2 * else executed");
    }];

    [CronTabCenter addCronJob:@"3" forBlock:^{
        NSLog(@"3 executed");
    }];

When we launch the app for the first time, it will log the result

 1 1 executed
 1 * executed
 2 * else executed

And when we launch the app for the second time,it will log the result

 2 1 executed
 2 * executed

And when we launch the app for the third time,it will log the result

 2 * else executed
 3 executed

And when we launch the app for the forth time,it will log the result

 2 * else executed
