Initializing the SDK

There are main thread initialization and subthread initialization APIs. Call either of them before calling other APIs.

initWithConfig

API Description

This API is used to start and initialize the SDK.

Precautions

You must call the initialization API before calling other APIs.
The initialization method must be called in the main thread.
The return value only indicates whether the API is successfully called.

Method Definition

    
         + (BOOL)initWithConfig:(HWMOpenSDKConfig *)config;

Parameter Description

**Table 1** Parameter description
Parameter	Mandatory	Type	Description
config	Yes	HWMOpenSDKConfig	Initialization information set.

**Table 2** HWMOpenSDKConfig parameters
Parameter	Mandatory	Type	Description
appId	Yes	NSString *	App ID. For details about how to request an app ID, see Requesting an App ID in Developer Guide.
appGroupIndentifier	No	NSString *	App group of the screen sharing extension. If this parameter is not transferred, the screen sharing function cannot be used. This parameter is used for communication between the sharing process and the main process during screen sharing. For details, see Apple's extension documentation.
siteType	No	HWMSdkSiteType	Login site type. The default value is HWMSdkSiteTypeChina.
serverAddress	No	NSString *	Server address.
serverPort	No	NSInteger	Server port.
hideExternalLabel	No	BOOL	Whether to hide the External label in the participant list, host role transferring screen or chat screen. By default, the External label is displayed.
logKeepDays	No	NSInteger	Log storage duration. Valid value range is 3–30. The default value is 0. 0 indicates that logs are not deleted by day. Note: 1 and 2 will be converted to 3, and the values greater than 30 will be converted to 30.
disableIncomingLocalNotification	No	BOOL	Disables local push for incoming calls.

For details about how to request an app ID, see Requesting an App ID in Developer Guide.

**Table 3** Enumerated values of HWMSdkSiteType
Enumerated Value	Description
HWMSdkSiteTypeChina	Chinese mainland.
HWMSdkSiteTypeAP	Asia Pacific.

Return Values

**Table 4** Return value
Type	Description
BOOL	If the initialization succeeds, YES is returned. If the initialization fails, NO is returned.

Sample Code

   
        /// Initialization.
HWMOpenSDKConfig *config = [[HWMOpenSDKConfig alloc] init];
config.appId = @"fdb8e4699586458bbd10c834872dcc62";// Enter the applied app ID.
config.appGroupIndentifier = @"appGroupIndentifier";// App group of the screen sharing extension. This parameter is mandatory and used for communication between the sharing process and the main process during screen sharing. For details, see Apple's extension documentation.
BOOL result = [HWMSdk initWithConfig:config];
if (result) {
    NSLog(@"Initialization succeeded.");
}

The sample code in the typical scenario and API reference is pseudo code and cannot be directly used.

initAsyncWithConfig:callback:

API Description

This API is used to start and initialize the SDK in a subthread.

Precautions

You must call the initialization API before calling other APIs.
The return value only indicates whether the API is successfully called.

Method Definition

    
         + (void)initAsyncWithConfig:(HWMOpenSDKConfig *)config callback:(_Nonnull HWMSDKInitCompleteHandler)callback;

Parameter Description

See Table 1.

Return Values

None

Sample Code

   
        /// Initialization.
HWMOpenSDKConfig *config = [[HWMOpenSDKConfig alloc] init];
config.appId = @"fdb8e4699586458bbd10c834872dcc62";// Enter the applied app ID.
config.appGroupIndentifier = @"appGroupIndentifier";// App group of the screen sharing extension. This parameter is mandatory and used for communication between the sharing process and the main process during screen sharing. For details, see Apple's extension documentation.
[HWMSdk initAsyncWithConfig:config callback:^(HWMSDKERR errCode, id  _Nullable result) {
    if (errCode == HWMSDKSdkerrSuccess) {
    NSLog(@"Initialization succeeded.");
    } else {
        NSLog(@"Initialization failed");
    }
}];
