指令, similar to the C # # include, contains (copies) the contents of a file to the location of the preprocessing directives.2> the #import 1) The foundation framework contains many commonly used classes and functions, such as String processing class NSString, log output function NSLog. Its importance is equivalent to the java.lang.* in Java2) Location of foundation framework and Foundation.h files:3> I said in the third of the C language topic:. h is called a header file and is generally used to

In many cases, the software uses parsing a text file, such as parsing a TXT file, reading useful data and processing it; or reading a stream file to find out the corresponding value. Example: // R, GR, GB, B per light source 0f12 4819 },/* Clock0, system clock 58 MHz, PVI clock 48 MHz, (PreView )*/ 0f12 f000 //, 16, 0 },P10 0f12 fa05 //, 16, 0 }, As shown above, the text structure is a sequence consisting o

we know who the murderer is and where it was killed, the last question remains, how did the murderer sneak into the victim's room?We're still going back to our just didn't see? 3rd: Let's look at Beanpostprocessor's registration and go back to the Registerbeanpostprocessors method in the Refresh methodSee, the killer was sneaking into the room at this time, and when spring is instantiated, the target object isSo far, we have basically known the basic process of homicide, but the details we have

Detailed explanation of the method for parsing and modifying XML content in the Python program, pythonxml RequirementIn actual applications, You need to modify the xml configuration file in real time, 1. add or delete some nodes 2. add, delete, and modify certain attributes of a node 3. add, delete, and modify the text of some nodes. Use xml documents Implementation ideaUse ElementTree to read the file and

that a segment may contain many areas. For example, each memory-mapped file has its own region in the Mmap segment, and the dynamic library has additional areas like BSS and data segments. The next article explains the true meaning of these "areas". Sometimes people refer to "Data segment", which refers to the whole data segment + BSS + heap. You can use the NM and objdump commands to view binary images, print their symbols, their addresses, paragraphs, and more. Finally, it should be noted tha
