छवि दर्ज करें यहाँ विवरण

मैं निम्नलिखित चित्र बटन स्थिति को प्राप्त करना चाहता हूं। जब "शुरू होता है .." क्षेत्र को छुआ जाता है, तो क्षेत्र को हाइलाइट किया जाता है और एक डेडेक्कर पॉप अप होता है। मेरा दृष्टिकोण पूर्ण-चौड़ाई वाला बटन बना रहा है और दो लेबल्स को स्थानांतरित करता है, आज की शुरुआत में 12:00 पूर्वाह्न। जब उपयोगकर्ता बटन को छूता है, तो मैं डेटपाकर को खींच कर कार्रवाई का जवाब देता हूं। ये मेरे प्रश्न हैं।

  1. क्या यह दृष्टिकोण परंपरागत है?

  2. मैं एक बटन को "चुने हुए" राज्य में कैसे बनाऊं? मैंने पृष्ठभूमि की छवि को बदलने के लिए निम्नलिखित की कोशिश की:

    UIImage * buttonImage = [[UIImage imageNamed: @ "btn_carrot.png"] resizableImageWithCapInsets: UIEdgeInsetsMake (18, 18, 18, 18)]; UIImage * buttonImageHighlight = [[UIImage imageNamed: @ "btn_light_carrot.png"] resizable चित्रमार्ग के साथ कैप्सइन्ससेट: UIEdgeInsetsMake (18, 18, 18, 18)]; [स्वयं। स्टार्टडेट बटन सेटबैकग्राउंड छवि: बटन छवि के लिए स्टेट: UIControlStateNormal]; [Self.startDateButton setBackgroundImage: buttonImageHighlight forState: (UIControlStateHighlighted | UIControlStateSelected)]

हालांकि, बटन एक चयनित राज्य में कभी नहीं जाता है यह अपने रंग संक्षेप में बदलता है बटन ट्रिगर करने के बाद हाइलाइट किया हुआ सेट करें:

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
