Use Ns_enum and Ns_options macros to define enumerations. Adopting modern Objective-cUse the Ns_enum macro to define a set of mutually exclusive enumeration values:typedef ns_enum (Nsinteger, Uitableviewcellstyle) { Uitableviewcellstyledefault, UITableViewCellStyleValue1, UITableViewCellStyleValue2, uitableviewcellstylesubtitle}; // type name: Uitableviewcellstyle Use Ns_options to define a value that can be combined:typed

When releasing the official version, you must block all background output.When developing applications, we often use nslog to debug our programs. As the

I don't know what this means? AAnswer: These macros are used for Conditional compilation. Generally, all the rows in the source program are compiled. However, sometimes you want to compile a part of the content only wh

ANSI compliant predefined macros: _ Date __: Indicates the date when the current source file is compiled. Format: Month/day/year (MMM dd yyyy ). _ File __: Name of the source file being processed. _ Line __: Indicates the row of the source file being processed. You can use the # Line command to modify it. _ Stdc __: Stands for the ansi c standard. It is defined as a constant integer 1 only when/Za is specified in the compiler option and is not compile

remaining macro names are discussed here. The _ d at E _ macro command contains a string in the form of month, day, or year, which indicates the date when the source file was translated to the code. The time when the source code is translated to the target code is included in _ t I m e _ as a string. String format: minute: second. If the implementation is standard, the macro _ s t d c _ contains the decimal constant 1. If it contains any other number, the implementation is Non-standard. You can

C language uses the va_list, va_start, va_end, and va_arg macros to define variable parameter functions, va_listva_arg Before defining a function with variable parameters, let's first understand the transfer principle of the function parameters: 1. function parameters are accessed using the stack data structure. In the function parameter list, the function parameters are imported from right to left. 2. Parameter memory storage format: the parameter me

[E liangshi Yiyou network ?] There may be some problems when writing macros. For example, the general goal is to write a macro containing a separate function call statement. This means that the caller needs to provide the final semicolon, while the macro does not. Therefore, the macro cannot be a compound statement enclosed by an arc. If this happens, a syntax error occurs during the call, just as if an else clause is added to the IF branch of the IF/

The following are very common macros and expressions that are useful in log statements.The preprocessing macro used in the C/c++/objective-c for log output.Macro Format specifier Description1. __func__%s before current function2.

In the C language, there are four predefined macros:Current file: __file__Current line number: __line__Current Date: __date__Current time: __time__These 4 macros are replaced by the compiler with actual values or strings when the code is compiled.Here is a snippet of code that compiles a code: TEST.C1 #include 2void main ()3{4 printf (" %s \ n%d \n%s \ n%s \ n", __file__,__line__,__date__,__time__); 5 }The result of his operation is:test.c 4

Today we animate the application and techniques of macros in PowerPoint presentations. In PowerPoint, we can also record macros to help us automate a series of actions. 1, the implementation of the "tools → macro → record new macro" command, open the "Record New Macro" dialog box, enter a name, press the "OK" button to record. 2, according to your needs, will be recorded in the process of operation, and

How do I implement data exchange between two cell ranges in an Excel table? Usually we use the Cut-and-paste method to complete, but this method is more cumbersome, if the data area is more prone to error. Let's try to write a " macro" that can implement that functionality. On the Tools menu, open macros, select Record new macros, and in the Personal Macro Workbook (Personal.xls), create a macro called Exc
