Default Init in iOS (Obj-C)

The standard advice is to use a "designated initializer" which ends up with me having to think, which is always bad. Here is a pattern that never fails, and you could put it in a UIView category (UIView+SharedInit) and be done with this forever.

- (void) sharedInit {

}

- (id) init

{

self = [super init];

if (self != nil) {

[self sharedInit];

}

return self;

}

-(id) initWithCoder:(NSCoder *)aDecoder {

    self = [super initWithCoder:aDecoder];

    if (self) {

[self sharedInit];

    }

    return self;

}

- (id)initWithFrame:(CGRect)frame {

    

    self = [super initWithFrame:frame];

    if (self) {

[self sharedInit];

    }

    return self;

}

This is for a UIView subclass only, of course, but you could do the same thing for other classes as well.
