how to create a breakpoint's log message action in xcode?

问题 Been watching a WWDC video today about new features in xCode 4. They have mentioned that it a good idea to use log message actions on breakpoints along with "automatically continue after evaluation actions" enabled to output a variable's value for instance instead of using NSLogs all the time. lets say I have something like that: NSLog(@"URL is : %@", userDocumentsURL); How would I write a log message action to display userDocumentsURL's value? Is it really a good idea to use the above method

How do you use Func<> and Action<> when designing applications?

由 我只是一个虾纸丫 提交于 2019-12-18 09:54:19
问题 All the examples I can find about Func<> and Action<> are simple as in the one below where you see how they technically work but I would like to see them used in examples where they solve problems that previously could not be solved or could be solved only in a more complex way, i.e. I know how they work and I can see they are terse and powerful , so I want to understand them in a larger sense of what kinds of problems they solve and how I could use them in the design of applications.

Web API 路由访问设置

由 心不动则不痛 提交于 2019-12-18 09:26:42
前段时间一直致力于MVC webapi 技术的研究，中途也遇到过好多阻碍，特别是api路由的设置和URL的访问形式，所以针对这个问题，特意做出了记录，以供日后有同样困惑的大虾们借鉴： 在Mvc WEBAPI中的APP_STARTA文件夹中有一个默认的api路由config文件设置： config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); 从中我们可以看出，api的路由访问是没有对应的action方法名的，默认的访问都是对应的controller的名称。因为api controller都有对应的类型的命名规则，get,post,以及对应的带参数的get,post方法等等，系统会根据URL请求的类型和参数来判别该使用哪个action方法，所以我在项目运行的时候，就感觉不是很方便，当要处理的方法过多，甚至经常会遇到的情况就是，请求类型相同，然后参数也相同的情况，这样系统就有可能很混乱，找不到正确的action方法，得不到我们想要的效果。为此，在适当的情况下，我们可以修改对应的默认路由设置，把路由改为： config.Routes.MapHttpRoute( name:

问题 I am attempting to use ctrl + click on a link to open it in a new tab. This is working fine in Chrome 58. Please find the code below: action.keyDown(Keys.CONTROL).click(driver.findElement(By.xpath ("//section[@class='filmStrip__basic']//a[text()='En savoir plus']"))).keyUp(Keys.CONTROL).build().perform(); I am using the same code on IE, Firefox and Safari but getting the following error: Firefox 54: The link is getting open in the same tab. IE 11: Nothing happening.. the control is moving to

Android - Want app to perform tasks every second

问题 I'm trying to get my countdown app to perform its function of updating my current time and date TextView and fire off its MyOnItemSelectedListener every second so that the app counts down dynamically instead of just when onCreate is initiated. If there is a more efficient method then rapidly firing off MyOnItemSelectedListener I would appreciate the criticism. public class TheCount extends Activity { TextView description=null; TextView dates=null; TextView times=null; TextView output=null;

iOS - passing arguments in action:@selector()

问题 I'm adding a button to a UITableViewCell programmatically. The method to be run when the button is pressed is - (void) quantityDown:(id)sender rowNumber:(int)rowNum , where rowNum is the row that the button appears in. When adding the target to the button, Xcode autocompletes the following: [buttonDown addTarget:self action:@selector(quantityDown:rowNumber:) forControlEvents:UIControlEventTouchUpInside]; But no matter what I try, I cannot pass the row number into the method. I assumed the

form action=“?login” : What does the question mark mean?

问题 <form action="?login" method="post"> <button>Login with Google</button> </form> I usually see the action refer to a php or html file but the "?login" stumps me. Background info: This is buried within the example-google.php file from lightopenid framework. I've been staring at the openid code to use google as a third party openid provider for user login on my web site and the sample code all works. Trying to get a clearer picture of what the framework is doing when the user presses the login
