I'm trying to setup keybinding for physically moving my current tab, either right or left of other tabs (rather than click and drag to rearrange them).
I know user defined keybindings are added to ~/.atom/keymap.cson, I'm just having trouble determining the command as I don't see it present in the default keybindings.
I found that Atom has a native keybinding set for this under as:
ctrl + shift + ←: pane:move-item-left
ctrl + shift + →: pane:move-item-left
The native bindings weren't showing up in Settings > Keybindings. Here they are:
'atom-workspace atom-text-editor:not([mini])':
'ctrl-alt-]': 'window:move-active-item-to-pane-on-right'
'ctrl-alt-[': 'window:move-active-item-to-pane-on-left'
You can take a look at Tab Move Key package. It is simple, you can use alt page up and alt + page down for moving tabs around.
command + [ = to move the block left by 1 tab
command + ] = to move the block right by 1 tab
Is there a way to search through all Xcode project files? I know that I can find some text inside file with finder, but finding something with Xcode will be very helpful. When I press cmd+f I can only find or find and replace in current display file.
Use cmd + shift + f for complete Xcode search.
To do it simply from the UI, with a click
By default, this will be searching through the entire project searching for any files containing the specific string you entered.
From this point, you can start doing more stuffs like replace all, etc, like this
On the left hand side of the editor you have a magnifying glass. There's a search box there. That should do the trick. (it's called the search navigator)
cmd + shift + f opens it too.
cmd + shift + f
then press return key of you keyboard.
Use Command + 3 a minimum keyboard shortcut
or Command + Shift + f
In find use: Find > Text > Containing
Right Click on any text and select 'Find Selected Text in Workspace'
In my experience, cmd + shift + f requires cmd + c before hand to populate the search term. So, my go to search for text in all files is to do the above.
I would like to search for all .xib files in a particular xcode project but I don't know how to do this on xcode. Also, suppose I want to search for a particular file, e.g. Test.h, how do I do this? I know how to do this using linux, but that gives the structure of the filesystem, and not of the xcode project.
In xcode on left pane at the bottom there is a search field, just type xib, it should list all xib files. Same with other type of searches as well.
Place your cursor in this "Filter" with a keyboard shortcut:
⌥ +⌘ + J , or by choosing from the File Menu Edit > Filter > Filter in Navigator
Edit:
You can even use wildcards. For e.g., *m*1.x* will filter SampleXib1.xib, It's also incase-sensitive.
To search a file/class ⌘ + ⇧ + O (Command + Shift + O)
To See the current opened file in Project Navigator ⌘ + ⇧ + J
To go to line number in a file use ⌘ + L
Note: This partially answers the question, to see all .xib you can search it in project navigator as mentioned by one of the answers. But I think these shortcuts are awesome!
Type your search keyword in the text field at the very bottom of the Project Navigator pane on the left.
Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
Now that Xcode 4 is officially released it's time for a follow up to my previous question: Hidden Features of Xcode
So what are they? What are those hidden little Xcode 4 hints & tips that you can't live without?
Please limit your tips to those that are new and specific to Xcode 4!
If you like your code to look as good as it runs, you've undoubtedly used #pragma mark - and #pragma mark <name> to provide a nice visual grouping in the Xcode class dropdown list. Xcode 4 now combines these into a single #pragma mark - <name>.
More on pragma mark.
shift-cmd-opt click on a symbol lets you tell Xcode exactly where in the UI you want the navigated-to file to open.
cmd-ret makes the version editor / assistant (the right hand pane) go away
shift-cmd-Y to hide the debugger
cmd-0 to hide the navigator (left pane)
cmd-[1..n] switch between navigators on left
cmd-opt-[1..n] switch between utilities (thing generally on right)
ctrl-[1..n] switch between various related files in the editor
Overall, Xcode 4 tries to keep things consistent w/the hot keys. Cmd is for mainline commands. Adding modifiers is for analogous commands focused on one particular sub-feature.
(These are just the four that come to mind as the my most pounded upon shortcuts that I'm using constantly! I'm sure it'll change over time as my workflow is refactored into the new hotness.)
Xcode 4 adds a new "Code Snippets" feature, accessible via View > Utilities > Code Snippet Library. To add a new code snippet, select some text in the editor view and drag it into the snippet library. You can either drag a snippet out and drop it in your code to use it, or, much more conveniently, assign a completion shortcut to it.
When you type in that series of letters, it will automatically show up in the code completion pop-up menu as you type your code. For example, among many others, I have a snippet set up so that typing "svk" will expand to setValue:<#value#> forKey:<#key#>. This can save a lot of typing and/or fishing around in the autocompletion menu for the methods and other code expressions you use the most. Xcode ships with a bunch of built-in snippets that come in very handy as well.
New shortcut I use most often: triple-finger swipe (up or down) to swap counterparts (between the interface and implementation files). No more hand acrobatics!

shift-option-click on a file in the Groups and Files list Project Navigator, or hold shift-option while choosing a file from the Jump Bar.
You'll get a pop-over from which to pick where to open the file. New or existing tab, new or existing split (Assistant) editor, new window—every possible option is there.
Tabs in Xcode 4 are awesome. Each one maintains its own separate layout, so you can have multiple tabs with different things in them and have each one lain out appropriately.
I've been setting up my projects with three layouts—one for the project object, one for each nib (showing the owner's class's sources), and one for each class.
There is one bug here: As of 4.0, Xcode will reset the state (turning off any Assistants) of the active tab when you reopen the project. The workaround is to switch to a tab with no Assistants for Xcode to close before you close the project. I have filed this as Radar number 9178441.

Here's the first. Tabs! Xcode 4 has replaced Xcode 3's useful but rarely used "favorites bar" with persistent tabs. This means you can keep a working set of commonly used documents in your tab bar.
Not exactly a hidden feature as such - but the fact that the tabs are persistent is perhaps easily missed.
If you're having any sort of trouble with the indexing of your project (e.g. symbols not showing up in autocompletion), open the Organizer window, click the Projects tab, and use the "Delete" button to delete the derived data for your project. This will force a rebuild of the project's index, as well as tossing out any built products.
Some useful hotkeys for working on smaller screens are:
cmd-shift-y - Hide and show the console/debug area
cmd-0 - Hide and show the file navigation
You can now associate groups in the Project Navigator with folders on disk. It always bugged me before that the Xcode 3 file view may not represent the actual structure of the project on disk.
Create a new group, then with the new group highlighted, open the File Inspector. In the identity section on the right just below the 'Path' is a small icon, click this to open the file browser dialog allowing you to select the directory for this group.
If you hold the FN key then you can scan through your document with the cursorkeys, without moving the cursor
Jump bar:
if your write outside function:
// FIXME: A Bug
// TODO: Later
// ???: ???
// !!!: !!!
// MARK: This a mark
Will like:
Also you can search:
Click with Option(With Shift at the same time, you can choice another window), you can see a dialog letting you specify where the file should open:
Source control:
If you use svn or git, discard change is easy:
Interface buidler
In xcode 4.2, you can jump to interface builder here:
Click a ui object with Shift, it will show a list of all objects under the point.
Try this:
Select a ui object, hold Option, then move mouse over other objects. It will like:
Other
Hotkey: Shift+Command+O Open Quickly
Try:
#error message
#warning message
And read:
Writing and Editing Source Code
Text Editor:
Cmd-clicking on a class name will take you to the implementation (or header) file of that class, cmd-clicking on an object will take you to where the object is declared.
Alt-clicking will open a documenation popup for the object you clicked on.
Adding frameworks: You cannot simply do this by right-clicking on the project or a group (like in Xcode 3). You need to go to the project view, select your target and go to "Build Phases" tab. Frameworks can be managed under the "Link Binary with Libraries" section.
Setting target dependencies: Similar to the above, in the "Target Dependencies" section of the "Build Phases" tab.
Keep your archives safe -prior to installing Xcode 4 (from 3). You will lose them (most likely) and with them lose your ability to symbolicate your crash logs.
Delete action-BEWARE: "Delete" (instead of "Remove Reference Only") directly erases the file from your drive. It doesn't go into the Trash, so you cannot recover it.
cmd-J jumps to the editor, but if you have more than one editor open you get an overlay that has all of the open editors. you can use cmd-→ and cmd-← to switch between the open editors.
Also, if you are having a hard time finding an option or property for anything the utilites window is probably your best bet:
hide and show utilities: cmd-opt-0
Things that are commonly hidden here that aren't intuitive:
data model entity properties.data model propertiesxib properties
You don't need to declare IBAction - methods in .h File. & You can directly connect it in Interface Builder.
Example:
-(IBAction)btnLogInTapped:(id)sender {
// place following method in .m file of your code. save file. Open the
// .xib file of viewController
// click on files owner
// click on connection-inspector.
// you can view your methods under "received actions"
}
You don't need to declare variables, if you are creating property for it.
Example:
// a property declared in .h File of your view controller.
#property (nonatomic, retain) LogInVCtr *nxtLogInVCtr;
// synthesize above property in .m File
#synthesize nxtLogInVCtr;
// or
#synthesize nxtLogInVCtr = _nxtLogInVCtr;
// and you are done, you don't need to declare variable for it.
One of my favorites is the "Open Tab" behavior preference. If you go to "Behaviors" in Preferences, you can set it to go to a specific tab whenever a run starts. You can name the tab, something like "Debug" and Xcode4 will create it for you if it doesn't exist, and take you there when you start debugging. You can configure this tab just how you like it for debugging sessions, and it will stick that way after you close it, so whenever you do a run Xcode4 will be set up just how you want it, in a separate tab. You can even tear this tab off to a separate window, in which case Xcode4 will open a new specially configured "Debug" window each time you start a run! This feature is great because it keeps your regular code editing tab or window uncluttered with the log and debugger panes. Simply close the "Debug" window when you're done running and you can be back to your clean screen of code.
In XCode3, There was an option for "Rename the Project". Now, you just need to click twice ( second click slowly ) to rename the project & Its done.
To Limit the Number of Concurrent Build Operations
This is a (somewhat) hidden preference which allows you to define the number of concurrent compile tasks:
defaults write com.apple.dt.Xcode IDEBuildOperationMaxNumberOfConcurrentCompileTasks 4
To Disable Indexing in the IDE
This one disables code sense indexing, which can save a lot of resources in large projects:
defaults write com.apple.dt.XCode IDEIndexDisable 1
to reenable:
defaults delete com.apple.dt.XCode IDEIndexDisable
Note that you should quit Xcode, set the preference values as desired, changes take effect when you restart Xcode.
If you prefer using vim/emacs running on, say, Terminal, or any other external editor, you can just create your xcode project, add files and whatnot and then switch to editing said files using whichever edit suits you best; whenever you switch focus to an xcode4 window, the modified files will be reloaded( was also the case with Xcode3 ) and you can build / run your application.
Two kinds of Build location specification using XCode4 Preferences.
Location Specified By Targets - 'Build' Directory is located within your project directory.
Location in Derived Data ( Recommended by XCode, as you can see in screen shot ) - 'Build' Directory is located under DerivedData location specified ( e.g. here in my case, /Users/digicorp/Library/Developer/XCode/DerivedData )
Please look at following screen shots.
QUICK HELP
Ctrl + Option / Alt + f
Find the Quick help. For example,
#property (nonatomic, retain) NSString *strQuery;
My Text cursor is at NSString & if I press Ctrl + Option + f then It will show a quick documentation in the inspector/utilities.
You know in Xcode, you can press option - command - left/right arrows to switch between multiple files. But what are these files?
They seem to be the ones that have been opened. But is there any way to check what they are? And close some unwanted ones.
Or, any other way you know to switch between files??
alt text http://img19.imageshack.us/img19/8724/picture4asx.png
if you click on untitled.m it will bring up the 'history' although it really functions more like multiple open documents per window.
The 2 arrows to the left of it are equivalent to the command+option+arrow
command+shift+W will close the current open document and open the most recent
I dearly miss ctrl+tab for recent document list like in Visual Studio, Eclipse and others. They do it with the application switcher so why not in their editors ? And whats up with "Command + Option + Shift + T" shortcuts ? One thing I have noticed after switching to Mac is the use of lame shortcuts like that, "press cmd+ctrl+option+]+k to open bla bla". Have Apple developers 4 hands or something ? If I want to indent multiple lines it should have been just tab.
Apple and 3rd party developers doesn't seem to follow a standard like they do in the windows world, every app has its own way of doing things.
Your guess about
They seem to be the ones that have
been opened
is correct.
Here is some ways you can use to switch between files.
^1 popups loaded files
Command + Option + Up to switch between declaration and implementation files.
Command + Shift + D to quick open project related file.
Command + Option + Shift + T to reveal your file in the group list. And then select related one.
"Popup of include files" is also good one to browse files related to the current one.
"View -> Smart Groups -> All Files | Symbols | etc " and then Tab and type first letters. Tab. And choose one you want. Bind some keys for that.
Simpliest: Two finger swiping on the trackpad left-and-right.
Command + Option + left / right arrows - collapse code
Command + Ctrl + up / down arrows - switch between .h and .m
Command + Ctrl + left / right arrows - move backward / forward
