问题 What's the difference between run-time, e.g., [[UIDevice currentDevice] systemVersion] , and compile-time, e.g., __IPHONE_OS_VERSION_MIN_REQUIRED checking? When should you one over the other? Is __IPHONE_OS_VERSION_MIN_REQUIRED just a variable set in Build Settings? I've read the answers to How to target a specific iPhone version? and other related questions listed below. But, I just noticed that __IPHONE_OS_VERSION_MIN_REQUIRED = 30200 when I build & run on iPhone (4.3.1) with Xcode 4. Why?

问题 I'm a complete and utter noob, so be gentle! I'm using git gui, and never touching the command line interface. I'm a noob, and some of the people i'm working with are even noob-ey-er...

(Not working means that the default value remains in the text box until you manually

问题 I'm testing Java on a Windows Surface Pro. The Surface Pro has Java 7 Update 55, but does not have the JDK installed. I compiled a program on my MacBook from the command line using javac . The MacBook Has Java 8 Update 5 and it includes the JDK (obviously because I compiled on the MBP). When I move the program from the MackBook to the Surface Pro, I get the following error. Here, "moving the program" means copying the two *.class files to the new machine and trying to execute the byte codes.

问题 I need to take a built version of an C# application and change one of the reference dll's.

Is there a way to stop the loader from caring about the version of the dll so the dll will just attempt to load? 回答1: Yes, you can do this - see the MSDN article Redirecting Assembly

问题 Originally asked: What is the difference between Node.js 4.x branch with LTS (Long Term Support) and the 5.x branch (listed as Stable)?
