Objective-C Bracing Style

I'm Adam Preble and this is the bracing style I like. Please don't use it unless you (a) like it, or (b) are contributing to a project of mine.

Rules

• Braces go on the next line for:
  • Method definitions.
  • if blocks:
  • After case statements, but only if required by local variables within the case.
• Braces go on the same line on:
  • @interface and @implementation lines, when defining instance variables.
  • switch blocks
  • When passing a block 'inline' (preferred style of passing blocks).

Example

@interface QRTEmbracer : NSObject {
    // I don't put ivars in my header files,
    // but if I did, they would be braced like this.
}
@end

@interface QRTEmbracer () {
    int _count;
}
@end

@implementation QRTEmbracer

- (instancetype)init
{
    if (self = [super init])
    {
    }
    return self;
}

- (void)animate
{
    [UIView animateWithDuration:1.0 animations:^{
        switch (_count) {
            case 0:
                ...
                break;
            case 1:
            {
                int zebras = _count * 2;
                ...
                break;
            }
        }
    }];
}

@end
