Reformatting to have method parameters in a new line

Question

There are so many settings in the preferences for Code->Style->Objective-C. I'm looking for the right one to reformat this line of code

SCPropertyDefinition *test = [SCPropertyDefinition definitionWithName:@"created_at" title:@"Tweeted At" type:SCPropertyTypeLabel];

to this format

SCPropertyDefinition *test = [SCPropertyDefinition definitionWithName:@"created_at" 
                                                                title:@"Tweeted At" 
                                                                 type:SCPropertyTypeLabel];

(the point is to have the colons indention matching)

I guess the it should be in the Wrapping and Braces Tab, but I havn't found the right setting yet. Thanks for your ideas.

Answer 1

The setting you are looking for is Wrapping and Braces | Method call arguments set to Chop down if long with enabled Align by colon. Note that there are separate settings for Method parameters.

It seems like this option was removed from AppCode 2. Or moved, but I can't find it. I wish there was a hotkey to toggle a line between the two formatting forms. – Cataldo

No it's still there. You should go to settings->Code Style->Obj-C look for "Method parameters" and change "Do not wrap" to "Wrap always" or "Chop down if long" – Philistine

This doesn't work anymore. I can't find any reference to Chop Down if Long in Appcode 3.3. Any alternatives? – Crossstitch

Editor > Structure > Format to Multiple Lines:

Shortcut: Ctl + M

From

ManyParamInit(param1: String, param2: String, param3: String)

To:

ManyParamInit(
    param1: String,
    param2: String,
    param3: String
)

Answer 3

It seems like as of App Code 2017.1 (perhaps earlier too) the align by colon option is not available in Swift. You can still tell App Code to chop a long argument/parameter list:

Selecting the whole constructor code and then pressing ^ M (control + M)
