Uploading an object

Sample code:

NSString *filePath = [[NSBundle mainBundle]pathForResource:@"fileName" ofType:@"Type"];
OBSPutObjectWithFileRequest *request = [[OBSPutObjectWithFileRequest alloc]initWithBucketName:@"bucketname" objectKey:@"objectname" uploadFilePath:filePath];
// Query the upload progress.
request.uploadProgressBlock = ^(int64_t bytesSent, int64_t totalBytesSent, int64_t totalBytesExpectedToSend) {
    NSLog(@"%0.1f%%",(float)floor(totalBytesSent*10000/totalBytesExpectedToSend)/100);
};
// Upload a file.
[ client putObject:request completionHandler:^(OBSPutObjectResponse *response, NSError *error){
    NSLog(@"%@",response.etag);
}];
