FFLettingYouKnow is a library for developers who want to support UIAlertView in iOS 7 and UIAlertController in iOS 8 without making separate, conditional calls for separate iOS versions; one call, that's all. This library is an easy-to-use wrapper for those two classes, abstracting away all such iOS version conditionalization. FFLettingYouKnow uses appropriate alert class depending on system version automatically.

How to Use

First, you need to get FFAlertClient object. It's highly recommended to use shared singleton object provided by library. Example:

FFAlertClient *client = [FFAlertClient sharedAlertClientWithTitle:@"Some title"
                                                          message:@"The message"
                                                cancelButtonTitle:@"Ok"];

Now you have an alert client with custom title, message and cancel button. Let's present it via simple instruction:

[client showWithCompletion:^(BOOL isCancelled)
{
}];

That's all that you need to present simple alert with one button. If you need more buttons, you can easily add them to the client:

FFAlertClient *client = [FFAlertClient sharedAlertClientWithTitle:@"Some title"
                                                          message:@"The message"
                                                cancelButtonTitle:@"Ok"];

FFAlertButton *secondButton = [[FFAlertButton alloc] initWithTitle:@"Second action"
tapHandler:^
{
    NSLog(@"Second button tapped");
}];

[client addButton:secondButton];

[client showWithCompletion:^(BOOL isCancelled)
{
}];

Now you'll get an alert with two buttons with Ok and Second action titles.
