今天继续分享使用Xcode编写ios代码，会涉及方法参数的切换、查找和替换、方法的文档等。

具体如下：

When a method or function contains parameters or arguments, code completion includes a placeholder for each. To move to the next placeholder, press Tab and to move to the previous placeholder, press Shift-Tab.



To find and replace text in the source editor, choose Find > Find and Replace (or press Option-Command-F). The search controls appear above the source file. As you type the search string in the first field, Xcode searches the file and highlights the occurrences
of the string. Enter a replacement string in the second field. To replace all occurrences, click All. To replace the occurrence and find the next, click Replace.



To find strings in your entire project, choose Find > Find in Project or select the find navigator () in the navigator area. Enter text in the search field followed by Return and Xcode displays occurrences of the string in the entire project. Select an occurrence
to view it in the editor area. To scope the search, above the text field, choose a type of string and options. To find all occurrences that start with a string, choose Find > Text > Starting with. To find symbols that start with a string, choose Find > Definitions
> Starting with.



To view a symbol declaration, Option-Command-click the symbol in the source editor. Xcode opens the assistant editor (next to the source editor) and displays the file containing the symbol declaration. To remove the assistant editor, click the close button
in the upper right corner. To navigate to a file without opening the assistant editor, Command-click the symbol. Alternatively, use the jump bar at the top of the source editor to navigate to methods and properties.



To read a description of a symbol, Option-click the symbol and a Quick Help appears. To view the full documentation for a symbol, click the Declared In or More link. To dismiss a Quick Help, click anywhere in the source file.



To search for symbols in my project and across the system frameworks, choose File > Open Quickly (Command-Shift-O) from anywhere in your project. In the search field popover, enter text followed by Return.
