iphone - creating a bar with core animation -

-

So I'm trying to use Apple Core animation to an animated bar graph. The bar is basically a rectangular shape, which is 0-100%. When it first appears, I wanted to show it the animation going from 0 to x%. How can I create a rectangular form like this?

Update: Most likely I will have an image once, so I need to enliven this image at a certain height ...

It should do exactly what you want: 

  - (UIImageView *) Create New Bar with Float ) Percentage: Location (CP point) Location {UIImageView * newBar = [[[UIImageView alloc] initWithFrame: CGRectMake (location.x, location.y, 50, 200)] autorelease]; NewBar.image = [UIImage imageNamed: @ "Bar Page"]; Kyabsiknimsn * Skletvlua = [Kyabsiknimsn Animsnvithkeypth: @ "Tronsformkskelky"]; ScaleToValue.toValue = [NSNumber Number explosion: percent]; ScaleToValue.fromValue = [NSNumber Number explosion: 0]; ScaleToValue.duration = 1.0f; ScaleToValue.delegate = self; NewBar.layer.anchorPoint = CPPointmake (0.5, 1); [Nvbrkleyr Addnimsn: Skletvlua Forky: @ "Skleup"]; CGAffineTransform scaleTo = CZP Transformmaskel (1.0 F, Percent); NewBar.transform = scaleTo; Return to Newbara; }

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...
