ios - How to open call out MKAnnotationView programmatically? (iPhone, MapKit) -


I want to open the callout for a MKPinNnotationView program, for example I can add 10 pins on the map I'm dropping, and I want to open the closest one. How can I go about doing this?

Apple has specified the 'selected' parameter for MKAnnotationView's , but frustrated it by setting it straight (it does not work, it has tried to do it) .

For the rest, only one set in MKAnnotationView is highlighted ( same story ), and ShowCallout method.

Any indication if this is all possible?

Make a visual method in your map viewer: 

  - ( Zero) Open annotation: (ID) annotation {// mv is map view [MV select: animated annotation: yes]; }

You can then determine the closest annotation based on the current location and can run the available annotations in the array. 

  [mv annotations];

After calculating the closest annotation, call: 

  [Auto open annotation: closest annotation];

Map view should be automatically scrolled to move its annotation to the center of the display area.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
