Xcode and #pragma mark iphone 开发中的小技巧

Xcode and #pragma mark

http://macdevelopertips.com/xcode/xcode-and-pragma-mark.html

I’ve started using #pragma mark directives in my code to help with organization as my implementation files grow. #pragma mark is simple to use, for example, insert the following to call out initialization code:

 

#pragma mark -

#pragma mark Initialization

 

 

 

Once this is in place, the Functions Menu (in the navigation bar) which shows a list of locations within a source file (e.g. definitions of classes, functions and methods) will display a new marker with the label "Initialization." The code in line 1 will add a line separator inside the Functions Menu, in this example, with the line appearing above the "Initialization" marker.

The figure that follows shows an example of how you might use #pragma mark to divide up various sections of your code.

Two notes:

1. You cannot have a space after the "-" in the #pragma mark -
2. If your code does not appear as expected (e.g. the separator does not appear), check that ‘Sort list alphabetically’ is not checked in the Code Sense preference settings.

 xcode 默认是 按照 字母顺序排列的。

所以看不到上面的效果， 改一下就好了。

这样的话 ，方法提示好多了。
