iphone - ViewController Transition Trouble -


मेरे पास वर्तमान कोड है: 

  (IBAction) साइनअप: (आईडी) प्रेषक {साइनअप * साइनअप = [[साइन अप alloc] init]; SignUp.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [आत्म वर्तमान ViewController: साइनअप एनिमेटेड: हाँ];   
 मुझे नीचे की रेखा पर केवल एक त्रुटि मिल रही है यह पढ़ता है: '' लॉग इनदृश्य '' के लिए कोई दृश्यमान अंतरफलक 'चयनकर्ता उपस्थित वीकंट्रोलर: एनिमेटेड।'  
 यहाँ वो है जो मुझे नहीं समझता ... मैं  loginView  के रूप में एक इंटरफ़ेस  UIViewController  वर्ग का बच्चा ... यह वह जगह है जहां  presentViewController  घोषित किया गया है। यह मुझे बता रहा है कि यह कुछ भी नहीं पा रहा है और मैं इसे कैसे ठीक कर सकता हूं?  
 आप समय के आगे धन्यवाद!   
 
 
 क्या आप सुनिश्चित हैं कि  presentViewController: एनिमेटेड:  को  UIViewController  में घोषित किया गया है? मेरे डॉक्स में इसे  presentViewController: एनिमेटेड: पूर्णता:  के रूप में सूचीबद्ध किया गया है। यदि आपके पास कुछ नहीं है तो आप एक पूर्ण समापन ब्लॉक प्राप्त कर सकते हैं  <पूर्व>  [आत्म वर्तमान ViewController: साइनअप एनिमेटेड: हाँ पूरा: ^ () {}];

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
