Fixes formatting of ObjC message arguments when inline block is a first
argument.
Having inline block as a first when method has multiple parameters is
discouraged by Apple:
"It’s best practice to use only one block argument to a method. If the
method also needs other non-block arguments, the block should come last"
(https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/WorkingwithBlocks/WorkingwithBlocks.html#//apple_ref/doc/uid/TP40011210-CH8-SW7),
it should be correctly formatted nevertheless.
Current formatting:
[object blockArgument:^{
a = 42;
}
anotherArg:42];
Fixed (colon alignment):
[object
blockArgument:^{
a = 42;
}
anotherArg:42];
