# Block Party! 

Lego the delegate pattern.

## De-delegatized

Use Block Party to replace all the delegate callbacks with blocks (or just some--delegate callbacks still fire in all cases).

#### Core Bluetooth (CBCentralManager, CBPeripheral and CBPeripheralManager)

##### CBPeripheralManager

```objective-c

[self.peripheralManager prt_peripheralManagerIsReadyToUpdateSubscribersHandler:

  ^(CBPeripheralManager* manager) {

    [self sendData];

  }];

``` 

    

##### CBPeripheral

```objective-c

[peripheral prt_discoverServices:services

                      completion:^(CBPeripheral* peripheral, NSError* error) {

                        if (error) {

                          NSLog(@"error discovering services %@", error);

                        } else {

                          for (CBService* service in peripheral.services) {

                            if ([service.UUID.UUIDString isEqualToString:TRANSFER_SERVICE_UUID]) {

                              self.foundService = service;

                              NSArray *characteristics = @[ [CBUUID UUIDWithString:TRANSFER_CHARACTERISTIC_UUID] ];

                              [self.peripheral discoverCharacteristics:characteristics

                                                            forService:self.foundService];

                              break;

                            }

                          }

                        } 

                      }];

```

#### UINavigationController

```objective-c

[self.navigationController prt_pushViewController:someViewController

      animated:YES

      preparation:^(UINavigationController *navigationController,

                    UIViewController *presentingViewController) {

        NSLog(@"Hi! I execute before the nav push!");

      }

      completion:^(UINavigationController *navigationController,

                   UIViewController *presentedViewController,

                   NSArray *poppedViewControllers) {

        NSLog(@"Hi! I execute after the nav push!");

      }];

```

## Utilities

### PRTAssert

Ever wanted a fail-fast assert during development and a graceful exit in production? If you've ever written something like this:

```objective-c

NSAssert(expression, @"something went wrong");

if (expression) {

  NSLog(@"production success code");

} else {

  NSLog(@"production failure code");

}

```

then you can combine the assert and conditional using this utility macro:

```objective-c

PRTAssert(expression,

          ^{ NSLog(@"production success code"); },

          ^{ NSLog(@"production failure code"); },

          @"something went wrong")

```
