ios - UINavigationController add Right button -

-

I know this question was asked many times but I could not find my status: I have 1 in the main window The UIAV controller is the main window- ?? Atoms also UITableView when I select the row, navigation controller pushes another UIViewController with nib. This UIViewController is not a navigation controller, it's only inside UITableView.

Here is a screenshot of this UIViewController:

Enter image details here

This is not the main window. UINavigationController with UITableView in the main window.

And here's the question:

When I add UIBarButtonItem to the NavigationalTime, am I pushing UIViewController?

Create an UIBarButton instance inside that extension view controller's .m file, and do it yourself set on. NavigationItem rightBarButtonItem You can do it in the init method. 

  UIBarButtonItem * barButton = [[UIBarButtonItem alloc] initWithTitle: @ "Heading" style: UIBarButtonItemStyleBordered Target: Self operation: @selector (someMethod)]; Self.navigationItem.rightBarButtonItem = barButton; [Barbeton release];

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...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
