GUNAlert

GUNAlert is a simple wrapper around UIAlertView and UIAlertController. For applications that need to keep backward compatibility with iOS versions < 8. It is designed as a simple drop in solution for most common use cases.

Usage

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Setup

Before using alerts you will need to instantiate GUNAlert class and make sure it's reference will not disappear until the alert is handled. Here's an example:

In your UIViewController create an instance of GUNAlert class and assign it as a strong property.

@interface MyViewController ()
@property (strong, nonatomic) GUNAlert *alert;
@end

@implementation GUNViewController
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.alert = [[GUNAlert alloc] initWithViewController: self];
}
@end

In most cases you will want to inform user about a fact and acknowledge it or make a decision. To facilitate this GUNAlert provides two helper methods:

Showing a 'Cancel' alert

To instantiate 'Cancel' alert or in other words alert with one action use the following method:

    
[self.alert cancelAlertWithTitle:@"Success!"
                         message:@"You've just won a lottery."
                     cancelTitle:@"Yay!"
                   cancelHandler:^{
                       [self transferLargeSumOfMoney];
                   }];

Showing a 'Cancel & Ok' alert

To instantiate 'Cancel & Ok' alert or in other words alert with two actions use the following method:

    
[self.alert cancelOkAlertWithTitle:@"Your meal is ready!"
                           message:@"Do you want something to drink?"
                       cancelTitle:@"Not really"
                     cancelHandler:^{
                         [self prepareOrder];
                     }
                           okTitle:@"Sure I do"
                             okHandler:^{
                                 [self addDrinkToOrder];
                                 [self prepareOrder];
                             }];

Showing an alert with more than 2 actions

First prepare an array with titles for each action.

NSArray *titles = @[
  @"Yes",
  @"No",
  @"Maybe"
];

Then prepare an array of handlers for each action. Both arrays must have the same number of elements.

NSArray *handlers = @[
  ^{
    [self makeACall]
  },
  ^{
  },
  ^{
    if (arc4random_uniform(2)) {
      [self makeACall]
    };
  },
];

Finally use both arrays in the following method:

[self.alert alertWithTitle:@"Hey I've just met you"
                   message:@"Call me"
                    titles:titles
                  handlers:handlers];
