`– initWithConfig:appKey:`

Initialize and return a newly allocated connection object.

- (id)initWithConfig:(SKYLINKConnectionConfig *)config appKey:(NSString *)appKey

Parameters

`config`	The connection configuration object.
`appKey`	APP key.

Discussion

Changes in config after creating the object won’t effect the connection itself.

Declared In

SKYLINKConnection.h

`– connectToRoomWithSecret:roomName:userInfo:`

Join the room specifiying the shared secret, room name and user info.

- (BOOL)connectToRoomWithSecret:(NSString *)secret roomName:(NSString *)roomName userInfo:(id)userInfo

Parameters

`secret`	Shared secret.
`roomName`	Name of the room to join.
`userInfo`	User defined information. May be an NSString, NSDictionary or NSArray.

Return Value

NO if a connection is already established.

Discussion

It is recommended to use connectToRoomWithCredentials:roomName:userInfo: but if the client application has no server implementation then this one should be used.

Declared In

SKYLINKConnection.h

`– connectToRoomWithCredentials:roomName:userInfo:`

Join the room specifiying the calculated credential info, room name and user info.

- (NSString *)connectToRoomWithCredentials:(NSDictionary *)credInfo roomName:(NSString *)roomName userInfo:(id)userInfo

Parameters

`credInfo`	A dictionary containing a credential, startTime and duration.
`roomName`	Name of the room to join.
`userInfo`	User defined information. May be an NSString, NSDictionary or NSArray.

Return Value

nil if connection can be established otherwise a message specifying reason for connection denial.

Discussion

The dictionary ‘credInfo’ is expected to have 3 non-Null parameters: an NSString type ‘credential’, an NSDate type ‘startTime’ and a float type ‘duration’ in hours. The ‘startTime’ must be a correct time of the client application’s timezone. Both the ‘startTime’ and ‘duration’ must be the same as the ones that were used to calculate the credentil. Failing to provide any of them will result in a connection denial.

Declared In

SKYLINKConnection.h
