iphone - Programatically Control UIScrollView -


is there method of programatically controlling uiscrollview? in, getting value location, how far along scrolled , things , change position, scroll programatically?

hope can help, thanks.

i don't know either of @alexandergre or @jagostoni talking about. scrolling in uiscrollview easy.

i suggest take @ documentation uiscrollview: http://developer.apple.com/library/ios/#documentation/uikit/reference/uiscrollview_class/reference/uiscrollview.html

to scroll uiscrollview, use

- (void)scrollrecttovisible:(cgrect)rect animated:(bool)animated 

example:

[myscrollview scrollrecttovisible:cgrectmake(20, 20, 320, 480) animated:yes]; 

that scroll uiscrollview animation 20 on x axis, 20 on y , 320x480 height , width.

if want information of view self(for example frame visible) should use methods , properties uiview, it's uiscrollview's parent. check out uiview documentation at: http://developer.apple.com/library/ios/#documentation/uikit/reference/uiview_class/uiview/uiview.html

to frame visible, use

myscrollview.frame; 

do not mix content size

myscrollview.contentsize; 

but, said. use documentation!
