iOS Learning-23 Load Local TXT file, nsmutableparagraphstyle paragraph format, zoom animation

Ideas:

1.new an Empty suffix of. txt file, the contents of the essay copy a paragraph

2. Use NSString to receive local files, and then use a title to stitch strings

3. Create a Nsmutableparagraphstyle instance, set the title center, the title distance body interval

4. Create a Nsmutableparagraphstyle instance, set the body to the left, indent each paragraph at the beginning 10

5. Create an instance of the base animation, end with Agent listener animation

Don't talk more about the code
