Question

I can code well in web language ( HTML, CSS, JavaScript, PHP ) , i know that i use HTML and CSS to make the graphical user interface like ( form, radio, button, drop-down-selection)

In Xcode4 all the User Interface Object/Element are basically drag-n-drop, why i cannot code it ? Code it like CSS, give the position or size manually.

Answer 1

u can code everything that you can do with interface builder. for example drag and drop of a button would be

UIButton *button = [UIButton buttonWithType:somebuttonType];

then manually position it with

button.frame = cgrect(xpos,ypos,width,height);

and add it to the view u want to have it

[self addsubview: button];

all gui elements can be done in code . have a read of apples docs to check them out

edit: ah sorry i misunderstood. your heading says in objective-c or c++. you could always check out http://librocket.com/ . it appears to have some css html ui stuff for you
