Performing a Streaming Upload

Streaming upload uses OBSPutObjectWithDataRequest to obtain the data source. You can call putObject to upload the data streams to OBS. Sample code is as follows:

Uploading a Character String

static OBSClient *client;
NSString *endPoint = @"your-endpoint";
NSString *SK = @"*** Provide your Secret Key ***";
NSString *AK = @"*** Provide your Access Key ***";
    
// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
// Upload a character string in streaming mode.
OBSPutObjectWithDataRequest *request = [[OBSPutObjectWithDataRequest alloc]initWithBucketName:@"bucketname" objectKey:@"objectname" uploadData:[@"hello" dataUsingEncoding:NSUTF8StringEncoding]];
    
// Query the upload process.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
    NSLog(@"%@",response);
}];

Uploading a Network Stream

static OBSClient *client;
NSString *endPoint = @"your-endpoint";
NSString *SK = @"*** Provide your Secret Key ***";
NSString *AK = @"*** Provide your Access Key ***";
    
// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
// Upload a network stream in streaming mode.
OBSPutObjectWithDataRequest *request = [[OBSPutObjectWithDataRequest alloc] initWithBucketName:@"bucketname" objectKey:@"objectname" uploadDataURL:[NSURL URLWithString:@"DateURL"]];
    
// Query the upload process.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
   NSLog(@"%@",response);
}];

Uploading a File Stream

static OBSClient *client;
NSString *endPoint = @"your-endpoint";
NSString *SK = @"*** Provide your Secret Key ***";
NSString *AK = @"*** Provide your Access Key ***";
    
    
// Initialize identity authentication.
OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK];
    
//Initialize service configuration.
OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider];
    
// Initialize an instance of OBSClient.
client = [[OBSClient alloc] initWithConfiguration:conf];
    
NSString *filePath = [[NSBundle mainBundle]pathForResource:@"fileName" ofType:@"Type"];
// Upload a file stream.
NSData *uploadData = [NSData dataWithContentsOfFile:filePath];
OBSPutObjectWithDataRequest *request = [[OBSPutObjectWithDataRequest alloc]initWithBucketName:@"bucketname" objectKey:@"test/image1" uploadData:uploadData];
    
// Query the upload process.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
   NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
};
    
[client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
    NSLog(@"%@",response);
}];
