12.18 Print all subclasses in view

Give a view to print its child controls

-(NSString *) Digview: (UIView *) view

{

if ([View Iskindofclass:[uitableviewcell class]) return @ "";

1. Initialization

nsmutablestring *xml = [nsmutablestring string];

2. Label start

[XML appendformat:@ "<%@ frame=\"%@\ "", View.class, Nsstringfromcgrect (View.frame)];

if (! Cgpointequaltopoint (View.bounds.origin, Cgpointzero)) {

[XML appendformat:@ "bounds=\"%@\ "", Nsstringfromcgrect (View.bounds)];

}

if ([View Iskindofclass:[uiscrollview class]]) {

Uiscrollview *scroll = (Uiscrollview *) view;

if (! Uiedgeinsetsequaltoedgeinsets (Uiedgeinsetszero, Scroll.contentinset)) {

[XML appendformat:@ "contentinset=\"%@\ "", Nsstringfromuiedgeinsets (Scroll.contentinset)];

}

}

3. Decide if you want to end

if (View.subviews.count = = 0) {

[XML appendstring:@ "/>"];

return XML;

} else {

[XML appendstring:@ ">"];

}

4. Traverse all the child controls

For (UIView *child in view.subviews) {

NSString *childxml = [self digview:child];

[XML Appendstring:childxml];

}

5. End of label

[XML appendformat:@ "</%@>", View.class];

return XML;

}
