different types of fonts and names

In iOS development, there is often a piece of text that displays different colors and fonts, or the need to add lines or underscores to a few words. Before the online to find some information, some redraw Uilabel textlayer, some with HTML5 to achieve, are more troublesome, and many Uilabel properties also do not work, the effect is not ideal. Later I learned that nsmuttableattstring (string with attributes)

The assignment operator in PHP performs different actions on different data types. First, explain the behavior of the value assignment operator =. See the following example: Copy the code as follows: $ i0; $ j $ I; $ j0; echo $ j; print the output 0 $ arrarray (0); $ arr2 $ arr; $ arr2 [0 First explains the behavior of the value assignment operator =. See the fol

value, using $var=null to destroy the variable $var is actually to $var the content is set to NULL, In fact, it implies that any reference variable pointing to the content area can be used to destroy the contents of the content area. So, to destroy the variable $var words with unset ($var). PS: In fact, this way to assign value $var is just a reference, not a lot of memory, or to destroy not so-called, here This is said to be destroyed in unset way. The following is an example of "cited explana

As a beginner in PHP, I have been confused about the reference of PHP for a long time. I carefully read the user manual and did some experiments tonight, and finally understood the principles and details, in particular, = operator for different types of behavior. First, explain the behavior of the value assignment operator =. let's look at the example below: The code is as follows: $ I = 0; $ J = $ I; $ J

This process does not need to be written in the story syntax, because there is no place to put it. But it should be written in the requirement details/test cases. Well, this is the "batch create users" experience of the Martian products.Syntax of different types of stories Let's try to c
