I'm trying to get into Accessorizer, but every time I am trying it, I run into the same problem. I select some code (for example, multiple #property statements), hit cmd-c and move my cursor to the place I want the generated code to be.
I now use Accessorizer's menu, select Implementation and my copied properties are pasted in, instead of #synthesize statements. As far as I can see, I followed the setup instructions precisely. I don't like the difficult to use shortcuts, so I would like to use the system menu, at least for now.
Ah, so you need to invoke the Accessorizer text service by pressing shift-alt-cmd-0 instead of cmd-c. That sends the text to Accessorizer. Only after you've done this, you can use the Action Menu / press shift-ctrl-cmd-0.

I have been developing in zend studio and there is a feature I miss a lot in Xcode. When you are reading code in a main function and you want to go in a specific function to read something, you can click in the left area of your current line of code were your are, and a flag-mark appears in that line of code, so you can go anywere else in the code and it will be very easy to come back to that line of code you were before because there is a flag and you only have to click on it and you automatically go back. Does Anybody know a similar way to do this in Xcode?
Unfortunately, this feature was present in earlier versions of Xcode (up to Xcode3 IIRC) and was called "Bookmarks", but it was removed since then.
You can use breakpoints (and disable them) as a workaround, even if it's not perfect. I personally prefer using other tricks, like "Open Quickly" and named tabs.
Alternate trick 1 : "Open Quickly"
One trick is to use Command+Shift+O (or "File" menu > "Open Quickly") to quickly open a file. In the field that appears, you can type:
The name or parts of the name of a file.
Typing "MainViewController" will propose to jump to the MainViewController.h or MainViewController.m file.
Typing "MainVC" will work too, as well as "MainViewCtrl", as long as the order of the letters you type is the same as the full name.
Very handy to just type "ContTVCell" to open the ContactsTableViewCell.h file that is hidden deep in subgroups of my project for example
Similarly, you may also type the name or parts of the name of a symbol, especially a method name.
For example, typing tvcellforrow will list you all the definitions of -tableView:cellForRowAtIndexPath: it could find in your project and let to jump to the one you want
When typing (parts of) the name of a file, adding : followed by a number at the end will allow you to directly jump at the corresponding line
For example, typing mvc:50 will propose you to jump to line 50 of MainViewController.h or MainViewController.m
Another trick : using (named) tabs
Don't forget that you can open tabs in Xcode, which can be very handy in this kind of situation.
When you are editing a file at some interesting position, you can create a new tab to browse elsewhere and go at any other place… and then go back to your first tab to find the code where you left it at the time you switched to the other tab.
Don't forget that you can name your tabs (simply double-click on their title) to give them a more explicit title. You may then quite think of them as "named bookmarks" somehow
Likewise, don't forget that you can detach tabs in separate windows too, if you prefer (for example to keep them around and visible on your secondary screen while you edit another part of your code)
You can even combine this with the "Open Quickly" trick presented above: once you made the "Open Quickly" field appear and typed something into it, instead of just validating using the enter key:
use Alt+Shift+enter to let Xcode present you a small widget that let you choose where you want the file to open (in the current tab, in another tab, in the assistant editor, in a dedicated window…)
use Alt+enter to open the file using the alternate navigation defined in Xcode preferences (Xcode > Preferences > Navigation > Optional Navigation). By default, the behavior when opening a file while using the Alt key is to open the file in the Assistant Editor. Personally I changed that in my Xcode preferences as I prefer to make Xcode open the file in a separate tab instead, which makes Alt+clic much more useful.
Sure, all those tricks with "Open Quickly…" and "Tabs" do not replace the bookmarks feature that you are missing. But they are still nice alternate ways to jump quickly to any position in your code, even any specific line of any specific file in your project, wherever you are in Xcode (even without having to have the Project Navigator visible on the left part of your window), and let you have multiple editors in different tabs to go quickly back to a part of interest in your code
its on top of your editor i have added two pics just check them.
When you navigate to another place in Xcode, say, open a different file, or Command-click and jump to definition, you can go forward and back by swiping right or left on the trackpad with two fingers.
You can also use keyboard shortcuts: Ctrl+⌘+→ to go forward, or Ctrl+⌘+← to go back.
Finally, you can click triangular buttons at the top left in your edit area.
There is a go back button at the top left of the editor!
If that is not good enough, whar I do is misuse breakpoints to set flags in my code. The breakpoint navigator thus becomes a table of flags. It isn't much but there you are.
I'm using Xcode 4.3 for Objective-C development.
One feature that I like in other text editors (I know Xcode is an IDE), is jumping to a method definition within the same code file.
For example if I'm in #implementation of Calculator and calculator has 10 methods, I will like a way to jump between them.
If I press command+L I can jump to a specific line number, is there a way to jump in a similar way but to a method definition? e.g. instead of typing the line number to type only the beginning of the method name.
Can I open somehow a dialog box, type the beginning of a method signature and see instantly the search results and If I pick one method it will get me to it?
Is there a way to jump from a method to the next one?
I think this is what you're looking for:
Type ctrl-6 to activate the "Show Document Items" in the "Jump Bar". Then start typing part of the method you are looking for to narrow the results.
Example:
To jump straight to - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
Type ctrl-6, type "cellFor", arrow down so the method is highlighted, and press Enter. The Editor will jump right to that method.
Incidentally, you can use ctrl-1, ctrl-2, ctrl-3, etc. to access the different sections of the "Jump Bar".
If I understand you correctly, try Command-Shift-O. It also doubles as a file finder.
Perhaps I'm not understanding what you need, but it seems like you have a couple of options.
Control+Command+J should take you to a definition.
Control+Command+Up/Control+Command+Down will toggle between .h/.m files.
While in the .m file, I use the dropdown for the methods often.
If you want to press a command key sequence like Command + Option + ↓ to jump to the next method, or Command + Option + ↑ to jump to the previous method, there is no such animal in Xcode. Prior macOS development tools had such a capability, but Xcode is seriously lacking in the basics...
The fastest jump back and forth in methods in a source file is to perform a Command + F (Find) on [\-\+][ \t]*\( as a regular expression. Then you can Command + G (Find Next) to go to the next method or Command + Shift + G (Find Previous) to go to the prior method.
If you are disciplined in your method definitions, you might be able to search for - ( or + ( as a normal text string instead... a tad faster.
If this is a serious itch to scratch, maybe it is worth creating an Xcode plugin (as silly as this sounds for such a basic feature)... and post a link here for the rest of us ;-)
Select a symbol (could be a method, but doesn't have to be) and right-click (or control-click). The contextual menu that pops up has a "Jump to definition" command. Control-command-J is a shortcut for that.
If the thing you're looking for isn't visible, you can use the Search Navigator (Command-3) to search through the code.
Depending on what you're looking for, you may also find the Quick Help feature in the Utilities panel helpful. If you select a symbol, Quick Help will give you at least some basic information about that symbol. For symbols in the iOS or MacOS X API's, you get quite a bit of help. If you've selected your own symbol, it'll tell you where that symbol is declared, and you can click on the file name to jump to the declaration.
I don't think there's a command to jump to the next method (where in the method would you want to jump to?). If you have a need for that sort of thing, you might find Xcode's code folding features useful. You can fold an entire method or just some of the blocks within the method. Very helpful for getting the lay of the land when you're looking at a large file for the first time.
It'd be really handy to have collection KVC accessor snippets in xcode, as they're a pain to do by hand. Has anyone who's been using 4 for a while worked out how to add new ones?
(...we're allowed to talk about it now, right?)
Yes, it's quite easy - you just highlight text you want to use as a snippet and drag it into the snippets area (dragging selected text can be difficult, I find it works better if you drag from the left edge of the editor). It brings up a dialog box asking you to name it.
Also, you can have custom parameters in snippets - if you put the text <#paramName#> anywhere in the code you are dragging, when you use the snippet it will come up as a replaceable parameter that you can tab between just like in the official Snippets.
Also make sure to set a completion prefix, which makes it shorter to activate the snippet as you are typing. The nice thing about using Snippets over other solutions like global system text expanders, is that snippets can also be limited to being valid in a certain area of code - so for example a snippet that filled out a string formatting line can be marked as valid only within a block, not outside a method. That way the completion prefix only hits in areas where it's valid to use.
You can edit a snippet by clicking once on it, a box will come up with the snippet text and some other snippet settings you can edit.
A tip to help you drag the code every time, select text then click + hold (do not move mouse) until mouse pointer changes from "I" to pointer. You'll then be able to drag the selected text to the Code Snippet Library.
Drag the highlighted code to the Snippet library. (It can be stubborn and not want to drag. Holding the mouse button down for a moment before dragging seems to help.)
You can use Snippets to manage code snippets in Xcode. Check out this demo http://www.youtube.com/watch?v=il4kE4diy0k
Simply select the code, the press ALT key and drag it into the code snippets library and rename it there, Make sure to press the ALT key, other than this you won'n be able to drag it.
Say we have a TestClass with the 2 methods, -getSomeString and -getAnotherString, and we are editing the following code and the cursor is in the location shown:
NSString *aString = [TestClass get<cursorIsHere>SomeString];
Say I want to change it to use -getAnotherString. If I bring up the auto-completion popup and select the other method via hitting enter or tab, I'm left with:
NSString *aString = [TestClass getAnotherStringSomeString];
i.e., it doesn't replace the existing text but rather just inserts.
Is there a special keystroke to make it replace the remaining text?
See IntelliJ for reference.
I don't think that there is a one step operation to achieve this. My suggestion would be similar to Thomas Templemann, but rather than two steps of forward word select and then Delete, I would expand to the desired autocomplete, by bouncing on Control + . and then hit Option + forward delete, which kills to the end of the word.
I don't think so. I have always used the following
double click on getSomeString
press Escape (or your autocomplete key)
find replacement method
that double click step has never really bothered me, but I would be interested if anyone knows better!
My work-around for this problem is this: Since the cursor will be right after the inserted text, I just press Shift-Option-Rightcursor, which selects the word past the cursor, then I hit the Delete key.
You can use the Tab key to perform "replace" instead of "insert" when choosing the method from the auto-complete popup in IntelliJ 9 (don't know if it's available in previous versions).
This is a GUI application (actually MFC). I need a command window with the ability to display a prompt like such:
Name of favorite porn star:
The user should be able to enter text after the prompt like such:
Name of favorite porn star: Raven Riley
But I need to prevent the user from moving the cursor into the prompt area. Users should also be prevented from backspacing into the prompt in order to prevent the following:
Rrraven Rrrileeey Ruuuulez!!! Name of favorite porn star:
Also need to control text selection and so on. And finally, I should have no problem retrieving only the text the user entered (minus prompt text).
Will it be better to create my own window class from scratch (i.e inherit from CWnd) or should I reuse the Windows EDIT control (i.e. inherit from CEdit)?
A similar command window can be seen in AutoCAD and Visual Studio (in debug mode).
I think you'd be better off creating a subclass of CEdit and limiting filtering key-presses. I suppose the hard part is not letting the user move the caret to the prompt area, but you can probably write some code to make sure the caret always get sent back to where it belongs (the input part).
Anyway, if you really, really want to implement your own control (it's not that difficult after all) I recommend you read Jacob Navia's "technical documentation" on how he built the LCC compiler and environment. Actually, it seems the docs are not online anymore, but I'm sure you can get them through his e-mail (jacob#jacob.remcomp.fr).
Edit: I liked your previous example better. Keep it classy, LOL :)
I had a very similar requirement and did exactly what davidg suggested; subclassed a edit control and filtered key presses. This was actually using Qt not MFC but the principle will be exactly the same.
You need to remember to filter keys such as home as well as left and backspace. I just checked to see if the move would move the caret into the prompt and if it did ignored the keypress.
Another thing to watch for is pasting multiline text, you will have to choose whether to just paste the first line or all lines, adding the prompt on all lines after the first. When subclassing the control you get lots of behaviour which won't work exactly as you want it.
