objective c - Creating a error-handling UIView Overlay -


I have tab bar controller inside a navigation controller with a 320x411 image (except the status bar, and tab bar) I want to make a scene.

The picture is shown for network connection error.

Currently I have a tab bar in the view of the personal view of the item: 

  if (appDelegate.hasInternetAtStart == NO) {CGRect myImageRect = CGRectMake (0.0f, 0.0) F, 320.0f, 480.0) f); UIImageView * myImage = [[UIImageView alloc] initWithFrame: myImageRect]; [MyImage Set Image: [UIImage imageNamed: @ "NetworkError.png"]]; MyImage.opaque = Yes; [Self.view pushViewController: myImage animated: no]; [MyImage release]; }

However, it is permitting to touch and access the elements below.

Is there a correct way to show an error, or should I choose another option method?

I would like a single view, which will override all the other scenes in tab bar item, and if possible it can be set in app delegate ...

Did you try to launch your UIImageView from within the App Rep?

By doing so, shape the scene and your image, using a PNG transparency image of the entire screen, your error will display to the user without touching the NavController tab bar.

If you want to trigger it from outside the app representative, you can use NSNotificationCenter to create a Respondent in such an app representative. 

  // register listener [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector (showNetworkError) Name: @ "showNetworkError" object: zero];

And like it, call from outside the adial: 

  // post notification [[NSNetificationcenter default center] PostNotificationName: @ "ShotNetworkArror Object": Self];

Note that the selector is the name of the "show networkwork" function that shows the error UIImageView.

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

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. 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...
