<h2>Use #pragma for organization</h2>

You can use:

<pre><code>#pragma mark Foo
</code></pre>

... as a way to organize methods in your source files. When browsing symbols via the pop up menu, whatever you place in <code>Foo</code> will appear bold in the list.

To display a separator (i.e. horizontal line), use:

<pre><code>#pragma mark -
</code></pre>

It's very useful, especially for grouping together delegate methods or other groups of methods.

Most Java IDEs show a marker for these task tags in the scrollbar, which is nicer, but this also works.

Debugging - how to use GDB

Being new to this still, I find trapping and identifying faults a rather
daunting job. The console, despite it being a powerful tool, usually
does not yield very intuitive results and knowing what you are
looking at in the debugger can be equally difficult to
understand. With the help of some of they guys
on Stack&nbsp;Overflow and the good article about
debugging that can be found at
<a href="http://cocoawithlove.com/2008/10/debugging-tips-for-objective-c.html" rel="nofollow noreferrer">Cocoa With Love</a> it becomes a little more friendly.

Being able to quickly see all the methods that can be overriden from a super class. For example when extending UITableViewController I just type in my implementation:

and then I hit ESC to see all the methods from my superclass that begin with "ta" such as 

<pre><code>- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

<h2>Use the Class Browser to show inherited methods</h2>

Apple's API reference documentation does not show methods inherited from a superclass. Sometimes, though. it's useful to be able to see the full range of functionality available for a class -- including a custom class of your own. You can use the Class Browser (from the Project menu) to display a flat or hierarchical list of all the classes related to a current project. The upper pane on the right hand side of the browser window shows a list of methods associated with the object selected in the browser. You can use the Configure Options sheet to select "Show Inherited Members" to show inherited methods as well as those defined by the selected class itself. You click the small book symbol to go to the corresponding documentation.

blocks|key|1732244|text|这可能是不言而喻的，但如果您想要使用词内导航，请确保更改了空格中的键预设(在Expose+&+Spaces首选项窗格中)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1732245|我切换空格以使用Ctrl-Option+Left/Right。|1732246|编辑:要将空格设置为Ctrl-选项左/右，请选择“在空格之间切换：”弹出窗口并按住选项键。第一项将从Ctrl箭头键更改为Ctrl-Option箭头键。|1732247|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Might go without saying, but if you want to use intra-word navigation, make sure you change the key presets in for Spaces (in the Expose &amp; Spaces preference pane), if you use it.

I switched Spaces to use Ctrl-Option Left/Right.

Edit: To set Spaces to Ctrl-Option Left/Right, select the "To switch between spaces:" popup and hold down the Option key. The first item will change from Ctrl Arrow Keys to Ctrl-Option Arrow Keys.

Writing this line above all initialization methods will generate a nice heading in the dropdown menu above the editor.

Open Quickly

Shift + cmd + D
Start typing a file name you'd like to open. Very cool if you look for framework headers. They have nice comments too, sometimes additional info to the docs.

ESC

When your text-cursor is on a uncomplete method name for example, press ESC. It will shop up everything that might fit in there, and you can quickly complete very large method names. It's also good if you can't remember exactly the name of a method. Just press ESC.

I think these are the best ones I know until now.

I just discovered how to change the indentation behavior used in the text macros:

For example, if you are like me and don't like this:

<pre><code>if (cond) {
 code;
}
</code></pre>

but prefer this instead:

<pre><code>if (cond)
{
 code;
}
</code></pre>

then you can change this globally (for all languages) by setting the following defaults in the terminal:

<pre><code>defaults write com.apple.Xcode XCCodeSenseFormattingOptions -dict-add BlockSeparator "\n"
</code></pre>

This has been bugging me for years, I hope it is of some interest for someone else as well.

As for "Open Quickly" feature - it's great, but I've always missed TextMate's cmd-shift-t for browsing the projects and files (symbols, methods, etc). 

That's why I've released an Xcode plugin that provides just that. It's called Code Pilot and you might want to take a look at it: <a href="http://macoscope.net/en/mac/codepilot/" rel="nofollow noreferrer">http://macoscope.net/en/mac/codepilot/</a>

blocks|key|3842696|text|在shell构建阶段，您可以使用以下格式写入stderr：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3842697|<filename>:<linenumber>:+error+%7C+warn+%7C+note+:+<message>\n|offset|length|style|CODE|3842698|这和gcc用来显示错误的格式是一样的。filename:linenumber部分可以省略。根据模式(错误、警告、备注)的不同，Xcode将显示带有红色或黄色徽章的消息。|3842699|如果包含绝对文件路径和行号(如果错误发生在文件中)，则双击构建日志中的错误会让Xcode打开文件并跳转到行，即使它不是项目的一部分。非常方便。|3842700|entityMap^0|0|0|1M|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

In shell build phases you can write to stderr using the following format:

<code>&lt;filename&gt;:&lt;linenumber&gt;: error | warn | note : &lt;message&gt;\n</code>

It's the same format gcc uses to show errors. The filename:linenumber part can be omitted. Depending on the mode (error, warn, note), Xcode will show your message with a red or yellow badge.

If you include an absolute file path and a line number (if the error occurred in a file), double clicking the error in the build log lets Xcode open the file and jumps to the line, even if it is not part of the project. Very handy.

Pressing ⌥⇧⌘D activates "Open this Quickly", which navigates you to the first result from "Open Quickly" using the selected text. If the selected text is in the format <code>&lt;filename:lineNumber&gt;</code>, (with or without &lt;>) "Open this Quickly" takes you to the file plus line number.

You can combine this with the following tip: 

You can write logs that contain the filename and line number of the log entry using this macro: (Make sure to define -DDEBUG=1 on your C Flags used in your target's debug configuration)

<pre><code>#ifdef DEBUG
#define DLog(fmt, ...) NSLog((@"%s &lt;%@:%d&gt; " fmt), __PRETTY_FUNCTION__, [[NSString stringWithFormat:@"%s", __FILE__ ] lastPathComponent] ,__LINE__, ##__VA_ARGS__)
#else
#define DLog(format, ...)
#endif
</code></pre>

In your DLog() output, double-clicking on the "&lt;" character to select the <code>&lt;filename:lineNumber&gt;</code> and pressing ⌥⇧⌘D will open the line where the log is in the source code.

blocks|key|5260770|text|我是从Windows世界(和其他许多人一样)进入Xcode的，我遇到的第一个怪癖之一就是试图用TAB键“缩进选定的文本块”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5260771|通常，在使用Windows编辑器时，选择一个文本块，并且只要按下TAB+(或shift+TAB)键，选定的文本就会向右/向左跳转。然后，一旦确定了文本的新位置，就停止按TAB键。|5260772|好吧，在Xcode中，这是完全不同的，因为当你按TAB键时，整个文本块消失了，留下一张傻傻的脸，里面有一些愤怒……|5260773|但后来，仅仅是出于偶然或直觉或其他原因，有一天我发现了某种变通方法，可以达到在适当的windows编辑器下可能获得的相同效果。具体步骤如下：|5260774|然后，在不取消选择文本的情况下(如果需要，按SHIFT键)，扩展所选内容的开头并将其放置在您希望新文本出现的位置。|5260775|粘贴上述文本(通常为CTRL%2BV+(yuck+)前一个文本块被“新”文本块(当然是它本身)替换，但是Xcode的“自动缩进”功能(或者其他人，谁关心)会自动把文本放在我们在步骤3中选择的新位置上。|unordered-list-item|5260776|

I came into Xcode right from Windows world (as MANY others), and one of the first quirks which I was faced to, was trying to "indent a selected block of text" with the TAB key.

Typically, when using a Windows editor, you select a block of text, and whenever you press TAB (or shift TAB) keys, the selected text jumps right/left. Then, once you decide the new position of the text, you stop pressing TAB.

OK, in Xcode, this is completely different, because when you press TAB, the whole block of text disappears, leaving you with a silly face, and some anger inside...

But then, just by chance or intuition or something, one day I discovered some kind of workaround to achieve the same effect you might get under a proper windows editor. 
The steps should be these:

<ol>
<li>Select the text block as you might do under Windows.</li>
<li>Instead of pressing TAB, leave your instincts away, and "copy the text block" (typically CTRL+C (yuck)).</li>
<li>Then, without deselecting the text, (pressing SHIFT if needed), extend the beginning of the selection and place it on the position you would like your new text to appear.</li>
<li>Paste the beforementioned text (typically CTRL+V (yuck again)).</li>
<li>Result: The previous text block gets substituted by "the new" one (of course, itself), but the "auto indent" capabilities of Xcode (or someone else, who cares), will auto place the text starting onto the new position we chose in step 3.</li>
<li>A big smile appears on your face.</li>
</ol>

It's kind of tricky, but when you get used to it, you find yourself using it a lot.

Enjoy!!
