There is little need to use reflection tools directly; they are provided in the language only to support other Java features, such as Object serialization (chapter 10th), Java beans, and RMI (described later in this chapter). However, many times we still need to dynamically extract data related to a class. A particularly useful tool is a class method extractor. As noted earlier, if the view class defines a source code or an online document, you can se

1. PrefaceBecause the company has a foreign catering system, programming and development for 3-4 years, before the use of all non-arc, development to this year, the first batch of iterative development of the personnel has been missing, and now found that there is a lot of memory leaks, the system does not automatically release the freed memory. Once the app has been in use for a long time, memory is not released and the app is eventually blown. It in
[Swift learning] Swift programming tour --- ARC (20), swift --- arc
Swift uses automatic reference count (ARC) to track and manage the memory used by the application. In most cases, this means that in the Swift language, memory management is "still working" and you do not need to consider memory management on your own. When an instance is no longer in use,
The Xcode project often incorporates some old code, which may be in non-arc mode. Mixed compilation, you will encounter the situation of compilation error.How do I share arc mode and non-arc mode?In addition to providing the option to use ARC mode for the entire project, Xcode can also label individual files to specify
How to convert a non-ARC project into an arc project
Xcode has an automatic conversion function, but only suitable for smaller projects, not suitable for large projects, so large projects require full manual conversion.
1. Change the project compilation environment to ARC
Change the red circle from No to Yes

In the Xcode project we can use both arc and non-arc blending modes.If your project uses a non-arc mode, add the-FOBJC-ARC tag to the ARC mode code file.If your project is using ARC mode, add the-FNO-OBJC-
1. How to compatible with non-ARC classes in ARC mode

This example describes how PHP draws an arc. Share to everyone for your reference. Specific as follows:
The arc is equivalent to intercepting part of the ellipse. The code is as follows:Copy the Code code as follows: 1. Create a canvas$im = Imagecreatetruecolor (300,200);//Cre
Because there is no arc mechanism before, a lot of good libraries are used non-arc, or some Daniel still do not like to use arc, encapsulated class is non-arc, want to use these non-ARC class library in their own arc project, just

1. PrefaceOriginally thought that after the conversion to arc, no longer need to consider the memory problem, but in practice still found some memory problems need to pay attention to, today I do not talk about block circular reference problem, mainly say some objects, arrays not memory is not released in the case.2.

The reference to a third-party framework does not support ARC, and the third-party arc
We often encounter a problem when referencing a third-party framework and discovering that it does not support Automatic Memory Processing (ARC)
We need to do this:

Now our third-party file
It is generally necessary to modify the variables in the block to be modified in advance by adding blocks .In non-arc,the reference calculation of a block-modified variable is constant.In Arc, it is quoted and calculated as +1;Can be used under non-arc (arc directly using __weak)//非ARC__block typeof(self) weakSelf = se
