Recently, it was my turn to explain Mantle at the iOS technology sharing meeting of the company's mobile internet business department. So I went to the Internet to search for materials. Finally, based on the articles in the next three links, I read them in order and summarized them, it took three minutes to share with you what this Mantle was and how it was used.

JSON Parsing is believed to have been used by everyone, and JsonKit or the former SBJson will be used for ease of use. Mantle is as easy to use as JsonKit.

When we receive a return value in JSON format from the server, we first use JsonKit to parse it into dead JSON data, then, use Mantle to plug the dead JSON data into our OC object and use it as a living member variable. Saving the time for writing [[obj objectForKey: @ "key"] objectAtIndex: index] objectForKey: @ ""]... this long code can also be automatically converted to the required data type.

In Class 5 (1), there are 40 people studying paper-cutting. After everyone learns, they will teach others. If they teach the first person, it will take three minutes. How long does it take for the class to learn paper-cutting?

There are 1 in the first three minutes, 2 in six minutes, 2 in nine minutes × 2 = 4, and 8 in twelve minutes. The number of people who will paper-cut in every three minutes doubles. It takes 21 minutes to finish all their studies. It is worth noting that the last three minutes are not one-on-one instructors, but the time will not overlap, so it will take three minutes even if there is only one person left.

I am a junior high school student. The teacher asked me to write a speech about how to learn and how to introduce the learning method. It takes about three minutes to read it on the stage.

Junior high school students' learning methods
There are many factors that affect students' learning performance, such as their learning purpose, learning attitude, learning methods, innate genetic quality, acquired health condition, the educational level of teachers and parents, and whether the educational methods are appropriate, the influence of the campus environment and the social climate, the poor knowledge base, and the intelligence and ability. two of the most important items are as follows: one is to learn (objective attitude) and the other is to learn (learning method ).
It can be said that all students want to learn when they first enter the school. however, when dozens of students in a class are taught by the same teachers and use a unified textbook, the basics of entry are similar. After a while, there will be a gap in the score. with the passage of time, this gap will grow bigger and bigger, and the obvious polarization in the second grade is a typical example. what is the reason? Through investigation and research, it is found that although everyone wants to learn well, some will learn, and some will not. the students who want to learn are expected to earn a good score, which can stimulate interest, increase confidence, and want to learn more. the more you want to learn, the more you want to learn, the more intelligent you are, the more powerful you are, the more advanced you are, And a virtuous circle is formed. students who do not want to learn can't start to learn, but their scores are not good for the time being. If they can learn lessons in time and improve their learning methods, they will not learn or learn. After some effort, they can catch up. if you do not think about improvement or make effort, your score will get worse and worse. when the gap grows to a certain extent, it is not easy to catch up. at that time, you will lose interest in learning and will not want to learn. the less you want to learn, the worse your score. Then, you may have a kind of doubt about your self-ability. You think that you are not a learning material and have lost confidence, dislike, fear, or even refuse to learn. once this vicious circle is formed, it will surely become a failure in learning. this article analyzes the development process of these two types of students. The former follows the following path: Want to learn, learn, and want to learn. The latter follows the following path: want to learn-do not want to learn the route. the two routes start from the same point, and the different points are on the learning method.
It can be seen that whether to learn, that is, whether the learning method is scientific, is crucial for the majority of young students. what is a learning method is the means, methods, or approaches used for learning. as long as you are learning, you must adopt a certain method: whether this method is scientific or not, whether it is active or unintentional, to promote the rise of learning performance and improve learning ability, the role is big or small, but I have never thought about it, or I have never paid attention to it or studied it carefully. through investigation and observation, we will find that the learning process and methods of middle school students are diverse.
Before the course, some students knew nothing about the content that the teacher was about to talk about. They waited for the teacher to explain what the teacher was about and listened to what it was about, lack of enthusiasm and initiative for learning. some students carefully previewed the course and listened to the lesson in a targeted manner. They listened to the details, thought about and understood the difficulties, key points, and key points, and mastered the lessons in the classroom. the same is preview, and the methods are different. some books seem to look like novels. It is not easy to discover problems, but it is more difficult to grasp the internal links of teaching materials. Even if any problems are found, they do not stop to ask why, and do not follow the root to find out the source; when reading a book, some of them start to brainstorm, and find out the old concepts and old knowledge in the new lesson. If they can understand the problems in the new lesson, they will be able to understand the problems at the time, wait for the class to focus on the teacher's analysis and explanation.
In the classroom, some students concentrate and listen attentively; some are distracted and sleepy. they listen to lectures, some sound recorders, all listen to the records, some like stenographer, while listening and remembering a large book, there are a lot of problems; some listen to the main, while listening and thinking, remember the problem; some simply don't remember, just listen; some also listen and write while thinking. similarly, some think about the content in the classroom, some think about the knowledge system related to this lesson, some think about the ideas of teachers, and some compare their own ideas with the ideas of teachers.
After class, some students rush to do their homework and finish their homework. Some of them first recall the content of the study class, then read the books and take notes, and fully understand the teaching materials before they begin to do their homework. some do not understand the class, do not ask for it, with it, play dizzy dark.
Similarly, there are various practices in reading reference books, doing exercises, summarizing stages, reviewing exams, and analyzing exams.
The above is from each specific learning link. If we look at the overall learning process, there are many forms... the remaining full text>
