如何将缩放和旋转变换应用于视图？当我使用下面的代码时，只应用最后一个转换。

testV.transform = CGAffineTransformRotate(view.transform, keepRotation)
testV.transform = CGAffineTransformScale(view.transform, keepScale, keepScale)

让它像这样工作：

>>> import urllib2
>>> proxy_support = urllib2.ProxyHandler({"http" : "127.0.0.1:1080"})
>>> opener = urllib2.build_opener(proxy_support)
>>> urllib2.install_opener(opener)
>>> import json 
>>> data = json.load(urllib2.urlopen("https://www.google.co.in/trends/hottrends/hotItems?geo=IN&mob=0&hvsm=0"))
('216.58.220.3', 443)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/urllib2.py", line 127, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.7/urllib2.py", line 407, in open
    response = meth(req, response)
  File "/usr/lib/python2.7/urllib2.py", line 520, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python2.7/urllib2.py", line 445, in error
    return self._call_chain(*args)
  File "/usr/lib/python2.7/urllib2.py", line 379, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.7/urllib2.py", line 528, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 503: Service Unavailable
