? In fact, it is not difficult to understand. Basically, if you can understand the Conversion Relationship of the following code, your objective-C syntax can be roughly achieved: [[Myclass alloc] init: [Foo bar] autorelease]; The syntax for converting to C # or Java is: Myclass. alloc (). INIT (FOO. Bar (). autorelease ();3. Other things In fact, the previous articles on this site mentioned this. I will explain it in detail here. 1. ID: Objective

Why did the people who were just beginning to learn programming start with Hello World? Many people do not understand this problem, even some people deliberately do not start from Hello World. I have a classmate is deliberately not from Hello World start, he is from Hello xxx (xxx is his name) began, the result is, practicing n years, his code level is so rotten, often out of the bug, affecting the line running.Programmers are an industry, and like ot

overridden to implement the main function of this thread, This is also the way to implement the Runnable interface. Second, a class should be inherited when they need to be strengthened or modified. Therefore, if it is not necessary to rewrite other methods of the thread class, it is best to implement the Runnable interface in this case. three, in the disconnection processThe thread terminates when the thread's run () method executes the last statem

model, each country must have the capital, each city must belong to a country. This allows the two properties to be accessed directly after initialization (no optional expansion is required), while avoiding circular references. To meet this requirement, the Capitalcity property of country is declared as an implicit parsing of an optional type's property by adding an exclamation point (city!) at the end of the type. This means that, like other optional types, the default value of the Capitalcity

puzzle, like groovy to a DSL. I will record and discuss some of the language features, but will not discuss the likely important but trivial parts of most syntactic sugars. If it's just a pure study note that's boring, it's better to write it as a spit. I fought from Java and JavaScript to Haskell and groovy, and for these four languages, a feature is a feature-by-landscape comparison, such as standing at the angle of the type system, weak type, st

Let's talk about why you should learn Java behind your boss.There are two main aspects:1) Interest direction of the shift: the current work is the embedded direction, is the embedded direction is very just interested in the job before you think of yourself to take a plate tune a tune Toss Toss is also good.
