JSAlertView comes with few handy methods for showing simple alerts.

For example, if you want to display a simple alert with "Ok" button, you will have to write couple of lines of code as below

using UIAlertController:

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title" message:@"This is a simple alert." preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* okButton = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
    [alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:okButton];

[self presentViewController:alert animated:animated completion:nil];

using UIAlertView:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Title" message:@"This is a simple alert." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];

but using JSAlertView its short and simple,

[JSAlertView alert:@"This is a simple alert."];

OR

Alert(@"This is a simple alert.");

super easy, right?

Another handy method is for asking user a question, like a confirmation dialog,

[JSAlertView confirm:@"Did you like this alert?" withCompletionHandler:^(BOOL accepted) {
    NSLog(@"%@", (accepted ? @"YES" : @"NO"));
}];

Lastly, you can use the following method for full customization:

[JSAlertView alert:@"Alert with multiple buttons." withTitle:@"Alert Title" buttons:@[@"Button 1",@"Button 2",@"Button 3",@"Button 4",@"Button 5"] withCompletionHandler:^(NSInteger buttonIndex, NSString *buttonTitle) {
    NSLog(@"Pressed %@ at index %ld", buttonTitle, (long)buttonIndex);
}];

JSAlertView can be used for any iOS version without any worry for support for UIAlertView in any iOS version.
