Said drawer effect in iOS the more famous third-party class library is pprevealsideviewcontroller. When it comes to third-party libraries, it is natural to think of our cocoapods, today's blog with Cocoapods introduced Pprevealsideviewcontroller, and then in our project to code combined with storyboard to make drawer effect.I. Introduce third-party plug-in Pprevealsideviewcontroller in the project with Cocoapods.(1). Search for Pprevealsideviewcontroller versions in the terminal (2). Add the ap

this error results from a missing file-the compiled version of stdafx. CPP. visual c ++ does a poor job of keeping track of this file and frequently "forgets" how to build it. this problem often occurs after restoring a saved workspace from diskette without the DEBUG directory. to fix the error select stdafx. CPP from the workspace file list them choose compile from the build menu. if
1. Pointer conceptThe address of the variable is called the pointer of the variable, and the variable storing the pointer is called the pointer variable.A pointer variable is a variable that stores the address values of other variables. For exampleInt I;Int * pi = I;The pi variable value is the address of variable I.* Is added before the pointer to indicate the memory unit pointed to by the pointer. For exampleInt I, j;Int * pi;Pi = I;I = 9;J = * pi;Then the j and I values are the same.A point

Spring's client access to restful businessResttemplate is the core class of client access to restful business. Conceptually similar to other spring template classes, such as JdbcTemplate and Jmstemplate. The behavior of resttemplate can be customized by providing a callback method and configuration Httpmessageconverter (used to package the object into the HTTP request body and extract it from the returned response to an object). Because XML is generally used as a message format, Spring provides
Although I have some knowledge of the SQL Releaser, I have not written it since I have been working for nearly four years. I think many of my friends, like me, although ado.net is often used, it is nothing more than adding, deleting, modifying, and querying operations. The application of the Releaser is much less than the stored procedure. The most recent project requirement reminds me of the application scenarios of the Releaser.

Code for sorting strings (C)
Question: enter a string to print all the characters in the string.
Method: use recursion to switch positions sequentially and print the output.
Code:
/* * main.cpp * * Created on: 2014.6.12 * Author: Spike *//*eclipse cdt, gcc 4.8.1*/#include
void Permutation(char* pStr, char* pBegin);void Permutation(char* pStr){ if(pStr == NULL) return; Permutation(pStr, pStr);}void Permutation(char* pStr, char* pBegin){ if(*pBegin == '') {
Issue: Enter a string (requires no duplicate characters) to print out all permutations of characters in the character string.Idea: Ask for all characters that may appear in the first position, swapping the first character with the character one by one after it. The first character is fixed, and all subsequent characters are arranged. This time throw all the following characters into two parts: the first character of the following character, and all the characters after the character, and then ex

Title: Enter a string to print out all the permutations of the characters in the string. For example, the input string ABC prints out all the string ABC,ACB,BAC,BCA,CAB,CBA that can be arranged by the character A,b,c.Analysis: First of all the characters that may appear in the first position, that is, the first character and all subsequent characters are exchanged. In the second step, a character is fixed, and all the characters in the back are arranged. The following characters can still be use
The include files for Windows and MFC are very large. Even if there is a fast processing program, it takes quite a long time to compile the program. Since each. cpp file contains the same include file, it is silly to process these files repeatedly for each. cpp file.To avoid this waste, Appwizard works with the VisualC ++ compiler as follows:◎ Appwizard creates the stdafx. h file, which contains all the mfcinclude files required by the current project file. This file can change with the selected

This will speed up compilation and save time. The precompiled header file is generated by compiling stdafx.cpp, named after the project nam
