iphone - UINavigationController facing some problems -

-

I have created a UINavigationController in the UIView controller class where I program 

  - ( Zero) viewDidoadload [[Super Viewedload]; Self.title = @ "Hmmm"; Navigation Controller = [[UINavigationController alloc] init]; // Without this education, tableView appears blocked; navigationController.view.frame = CGRectMake (0, 0, 768, 1004); // & lt; NavigationController.navigationBar.barStyle = UIBarStyleDefault should fill the newly controller screen; NavigationController.title = @ "Hello"; [Navigation Controller Navigationbar Set Handled: No]; [Self.view addSubview: navigationController.view]; CGRect frame = CGRactam (100, 70, 200, 50); UIButton * button = [UIButtonTypeRoundedRect] with UIButton Button; Button.frame = frame; [Button Situation: @ State for "seed": UControlStateAnimal]; [Button addTarget: Self-action: @selector (myButtonClick :) forControlEvents: (UIControlEvents) UIControlEventTouchDown]; [Self.view addSubview: button]; }   
 Now click on the button Event  
  - (zero) myButtonClick: (ID) sender {SAPRetailExCustomerSalesOrderDetailViewTVC * customerSalesOrderDetailViewTVC = [[SAPRetailExCustomerSalesOrderDetailViewTVC alloc] initWithNibName: @ "SAPRetailExCustomerSalesOrderDetailViewTVC" bundle: zero]; [Navigation Push ViewController: CustomerSalesOrderDetailViewTVC Animated: Yes]; [CustomerSalesOrderDetailViewTVC release]; }   
 Here is navigating the view in the output but the button resides in my view !!! Apart from this, I have to click twice to get the button back in my navigation controller. That's because I do not have a title for my navigation bar, how do I set a title here? Can someone help me ???   
  "itemprop =" text "> 
 Your UIViewController should be in the navigation controller's child and not in other ways round. Your UIViewController is not responsible for its own navigation controller  
 Use UINavigationController's -initWithRootViewController: .. Where you can make your UIViewController object and add the view of the Navigation Controller to the window  
 What you are doing is incorrect: You see the view of the Navigation Controller add to the controller!

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
