没有显示TableView应该如何显示

Question

我在Xcode中创建了一个表格视图，当我运行该项目时，它的显示效果非常差（与图片相关）。 不知道可能是什么问题。 我所做的是：

content_type = 'multipart/form-data; boundary=----------ThIs_Is_tHe_bouNdaRY_$'
request_body = '----------ThIs_Is_tHe_bouNdaRY_$' +  '\n'+'Content-Disposition: form-data; name="include_target_data"' + '\n' + '\n' + 'top'+ '\n' + '----------ThIs_Is_tHe_bouNdaRY_$' +'\n' + 'Content-Disposition: form-data; name="max_num_results"' + '\n' + '\n' + '1' + '\n' + '----------ThIs_Is_tHe_bouNdaRY_$' +'\n' + 'Content-Disposition: form-data; name="image"; filename="img_2.jpg"' + '\n' + 'Content-Type: image/jpeg' + '\n' + '\n'
request_body1 = request_body.encode('utf-8')
request_body2 = imageData
request_body3 = ('\n' + '\n' + '----------ThIs_Is_tHe_bouNdaRY_$').encode('utf-8')
request_body4 = request_body1 + request_body2 + request_body3

content_type_bare = 'multipart/form-data'

# Sign the request and get the Authorization header
# use client key
auth_header = authorization_header_for_request(CLIENT_ACCESS_KEY, CLIENT_SECRET_KEY, HTTP_METHOD, request_body4,
                                               content_type_bare,
                                               date, path)

request_headers = {
    'Accept': 'application/json',
    'Authorization': auth_header,
    'Content-Type': content_type,
    'Date': date
}
try:
    # Make the request over HTTPS on port 443
    connection = http.client.HTTPSConnection(CLOUD_RECO_API_ENDPOINT, 443)
    connection.request(HTTP_METHOD, path, request_body4, request_headers)

    response = connection.getresponse()
    response_body = response.read()
    reason = response.reason
    status = response.status

finally:
    connection.close()

您需要实现heightForRowAt

func tableView(_ tableView: UITableView,heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 200
}
