boilerplate

问题 I'm using the MFMailComposeViewController to send an email from within an iPhone v3.0 application. I programmatically create the message body text and display it before showing the picker. At the bottom of my message body text is the string "Sent from my iPhone." Is there anyway to modify this text or prevent it from appearing? A cursory review of the MFMailComposeViewController Class Reference and quick Googling doesn't turn up anything. Thanks in advance. 回答1: As far as I know, this is a

问题 From an out of the box HTML5 Boilerplate install, i use the following code body { background-image:url('img/bg.png'); background-repeat:repeat-y; } In the style.css file and the background image does not appear, it still stays blank. Full css is here /* HTML5 Boilerplate */ article, aside, details, figcaption, figure, footer, header, hgroup, nav, section { display: block; } audio, canvas, video { display: inline-block; *display: inline; *zoom: 1; } audio:not([controls]) { display: none; }

问题 From the information available online it isn't difficult to understand what boilerplate code is. What I don't understand is why was there any need to name a repeated section of code as boilerplate code? I would be surprised if someone coined the term "boilerplate code" just for the sake of it. There must be some reason which I am unable to get my head around at the moment. Does being aware that a piece of code is boilerplate help a developer in any way? Is there something the dev needs to be

问题 I have a base class Base and two sub classes Foo and Bar . In Base I define a function with an optional argument. This argument is either given or fetched at runtime (not at definition time). The argument is always fetched in the same exact way, which leads to subclasses having a boilerplate line of code (sure it's one line, but it's just an example). Normally this would look like this: class Base(object): def greet(self, name=None): pass class Foo(Base): def greet(self, name=None): name =

问题 the fav icon in html5 Boilerplate doesn't work (doesn't show up) I have tried it on localhost and also on a server but in both the cases it didn't worked. Whats the to make it work .? 回答1: HTML5 Boilerplate doesn't use link elements for icons by default. Instead, it relies on the browser finding either favicon.ico or apple-touch-icon.png in the root directory. If you put HTML5 Boilerplate in a sub-directory, whether in localhost or on a server, either no favicon will appear or an existing

问题 I have a Direction Enum: Public Enum Direction Left Right Top Bottom End Enum And Sometimes I need to get the inverse, so it seems nice to write: SomeDirection.Inverse() But I can't put a method on an enum! However, I can add an Extension Method (VS2008+) to it. In VB, Extension Methods must be inside Modules. I really don't like modules that much, and I'm trying to write a (moderately) simple class that I can share in a single file to be plugged into other projects. Modules can only reside

问题 Android Studio has support for macros—which they like to call live templates—which is nice, but nobody anywhere bothers to explain how to use them, least of all Android Studio. It is obvious that the "fbc" live template was designed to make findViewById easier to use, but I can't figure out how to use it. How exactly do you use this template to produce a piece of boilerplate like this, for instance: EditText e = (EditText) findViewById(R.id.m); 回答1: After much fiddling, I did eventually

问题 I am just curious on how people solve this. I often write the same type of code all the time. For instance: new Thread() { //... //... //... //Change this line //... //... }.start(); I keep changing the line where it says "Change this line" and then starting a thread. This change can be one line or a few lines. How would I go about compacting this code? 回答1: Well, I guess you could run your java files through the C preprocessor... 回答2: You can use the template pattern to create a base class

问题 I think I'm misunderstanding the concept of the .clearfix class. Maybe somebody can help me out. I'm looking for a way to use float and clear without messing up my markup. So I thought, that's where .clearfix can be used for. Inside of an empty H5BP-project, my markup looks like: <div></div> <div></div> <div class="clearfix"></div> <div></div> <div></div> <div class="clearfix"></div> <div></div> <div></div> <div class="clearfix"></div> Below the result. I was expecting a tic tac toe-field,
