Getting started with Block and mblock At the beginning of iOS4.0, Block was born. It is actually a supplement to c's predictions. The book points out that it is an anonymous function with automatic variables. The Block is concise and the code is highly readable, therefore, it is favored by developers. This time, we will introduce the basic types of Block and the actual operations in the project. The Block format is as follows: Basic Type of Block 1. N

reference object is released, the variable will be automatically set to nil without the programCode. Blocks Blocks is imported from IOS 4 and can be understood as Lambda in Python or lisp. This concept has also been imported in C ++ 11. Similar concepts are also defined in ruby, smalltalk, and JSP. For more information, see the subsequent articles. In this section, we will mainly look at the circular references in block. For example, when a block object is defined using the copy attribute,

Navigation The effect is as follows: Preparatory work: 1. Create a new movie clip called Item_bg ~ In the ITEM_BG to add a rectangular block, the size of the button is about the same size, specific tune ~ Then name the link item_bg the movie clip "mblock" 2. Create a new movie clip named Item_en ~ () Adds a dynamic text box to the item_en, names the instance name "Itext", and resizes the text box to its own size. Notice here that in the lower r
