Apple introduced Nslinguistictagger in IOS 5 to analyze natural language. IOS 8 is out of Metal, providing the underlying access to the device's GPU. Last year, Apple added Basic neural network subroutines (Bnns) to the accelerate framework, allowing developers to build neural networks for reasoning (not training).This year, Apple has given us Core ML and Vision,

Block in IOS and lambda and ioslamloud in C ++ 11 Block in ios is a function pointer, but to be more precise, in fact, it should be regarded as object-c's support for lambda in C ++ 11 or a language variant. its actual content is the same, I have already introduced C ++ lambda. Now let's talk about block in

and use macros to replace all macros in your program with macro corresponding variables, each of which is a temporary memory and uses the global Const constant, which guarantees that there will always be only one copy of memory 2.4 How to use iOS projects Note 1: Constants cannot be defined in a PCH file, otherwise the definition of the constant is included in each file, resulting in a duplicate definition Note 2: In general, define a

original class produce name conflicts, the class overrides the original method because the category has a higher priority. 14. There are 3 main functions of the category: 1). Spread the implementation of the class across multiple different files or multiple different frameworks. 2). Create a forward reference to the private method. 3). Add an informal agreement to the object. Inheritance can add, modify, or Delete methods, and can add properties. For the understanding of the s

The block in iOS can be said to be a function pointer, but to be more precise, it should actually be the support of object-c to Lambda in c++11 or a variant of the language, the actual content is the same, C + + lambda I have a brief introduction, Now the block in iOSBlock's actual behavior and function are similar, the biggest difference is that the variable value can be accessed in the same scope.

Device used for testing: Windows XP Computer + iPad Available places: for example, in the school living area, connect to the VPN Server set up by yourself in the teaching area to access the Internet (of course, if you have the permission to

Overview The way data is stored in iOS development can be grouped into two categories: one is stored as a file and the other is stored in a database. For example, the previous iOS development Series-objective-c's foundation framework article mentions archiving, plist file storage, including preferences, which are essentially stored as files, saying that archiving or plist file storage can optionally be sav
