iphone - How do I load different custom pins or identifiers based off of their property values? -

-

I have objects that are & lt; MKAnnotation & gt; . I load this array in my annotations using the annotation:.

Method: 

  - (MKAnnotationView *) mapView: (MKMapView *) mapView viewForAnnotation: (id & lt; MkAnnotation & gt;) Annotation  < / Pre> 
 I have loaded each PIN using a custom image:  
  annotation view. Image = [UIImage imageNamed: @ "purp_pin.png"];   
 However, I do not want all the pins to be loaded with this image.   
 How do I do this         
 
 
 If you have a few custom properties in your object which corresponds to  MKAnnotation , in a way you can image To set it, access it in  viewForNnotation :  
  MyAnnotationClass * myAnnot = (MyNnotationClass *) annotation; If (myAnnot.someProperty == 42) Annotation View.image = [UIImage imageNamed: @ "purp_pin.png"]; Other annotations View.image = [UIImage imageNamed: @ "default.png"];   
 Make sure the annotation view is dequeued or created or not regardless of the  image  property is set.

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...
