iphone - Get correct bounds for navigationItem.titleView layoutSubviews -


मेरे पास UIView का उप-वर्ग है जिसे मैंने titleView < / Code> कोड का निम्न पंक्ति का उपयोग करके नेविगेशन आईटम का 

  self.navigationItem.titleView = tempview;

आसान पर्याप्त यह ठीक काम करता है मेरी समस्या यह है कि यह नेविगेशन आईटम में कभी-कभी rightBarButton अपडेट किया गया है (कभी कभी कोई बटन नहीं होता है, कभी-कभी एक मानक आकार बटन होता है, कभी-कभी एक बड़ा बटन होता है)।

मुझे लगता है कि मैं titleView के रूप में जोड़ दिया है कि tempview वर्ग की layoutSubviews विधि का उपयोग कर सकते हैं इसलिए मैं इसे इस में डाल दिया: 

  - (शून्य) लेआउटस्विअ्यूज़ {[सुपर लेआउटस्विअ्यूज़]; Self.mylabel.frame = self.bounds; }

यह काम करने के लिए प्रतीत नहीं होता है, क्योंकि यह शीर्षक दृश्य का सही आकार नहीं है जब rightBarButton आइटम अपडेट हो जाता है

मैंने यह भी गौर किया है कि एक बार जब वे छोटे हो गए हैं, तो वे आसानी से स्थिति बदलते हैं।

मैंने कोशिश की है setNeedsLayout और लेआउटअनुक्रमित लेकिन वे बस गलत सीमाओं के साथ दृश्य को "आकार बदलते हैं"।

मैंने यह भी सुनिश्चित किया है कि rightBarButton वस्तु शून्य पर सेट है,

P> अपने दृश्य को 

  के साथ कॉन्फ़िगर करें [स्व सेटअटोरिसिंगमास्क: UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth];

(शायद initWithFrame में)

तब कार्यान्वित 

  - (शून्य) willMoveToSuperview: (UIView *) newSuperview {[स्व सेटफ़्रेम: [नईसूपरेव बाउंड]]; }

अब आप अपना दृश्य कंटेनर के आकार से मेल खाते हैं, और स्वत: आकार बदल रहे हैं।

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...
