Come on, it's 2014! Why isn't code block evaluation assignment being used yet, as trends show it's the future!

UIButton* button = ({
    //initialize button with frame
    UIButton* button = [[UIButton alloc] initWithFrame:({
        CGRect frame = CGRectMake(10.0, 10.0, 200.0, 75.0);
        frame;
    })];
    //set button background color
    [button setBackgroundColor:({
        UIColor* color = [UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0];
        color;
    })];
    //set button title for state
    [button setTitle:({
        NSString* string = [NSString stringWithFormat:@"title words"];
        string;
    }) forState:({
        UIControlState state = UIControlStateNormal;
        state;
    })];
    //set selector
    [button addTarget:self action:({
        SEL select = @selector(method:);
        select;
    }) forControlEvents:({
        UIControlEvents event = UIControlEventTouchUpInside;
        event;
    })];
    //return button
    button;
});
[self.view addSubview:button];

whoa!

Or the exact results can be accomplished as such:

UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(10.0, 10.0, 200.0, 75.0)];
[button setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0]];
[button setTitle:@"title words" forState:UIControlStateNormal];
[button addTarget:self action:@selector(method:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
