isKindOfClass grab tag - ios

Question

I just want to grab the button tag 1~ 5 in ScrollView, other data do not need to grasp
(void)layoutScrollImages
{
UIImageView *view = nil;
NSArray *subviews = [weekscroll subviews];
CGFloat curXLoc = 0;
for (view in subviews)
{
if ([view isKindOfClass:[UIImageView class]] && view.tag > 0)
{
NSLog(#"%d",view.tag);
CGRect frame = view.frame;
frame.origin = CGPointMake(curXLoc, 0);
view.frame = frame;
curXLoc += (wScrollObjWidth);
}
}
NSLog(#"subviews = %#",subviews);
[weekscroll setContentSize:CGSizeMake((wNumImages * wScrollObjWidth), [weekscroll bounds].size.height)];
}
subviews = (
"<UIImageView: 0x1ba330; frame = (313 61; 7 5); alpha = 0; opaque = NO; autoresize = TM; userInteractionEnabled = NO; layer = <CALayer: 0x1bac00>>",
"<UIImageView: 0x1bc900; frame = (315 59; 5 7); alpha = 0; opaque = NO; autoresize = LM; userInteractionEnabled = NO; layer = <CALayer: 0x1bdde0>>",

Answer 1

As per printed log, only UIButtons are having tags and in sample code you are working on UIImageView, so use given code as per your requirement.
I have modified your code as below, just check it out.
for (id objView in subviews)
{
if ([objView isKindOfClass:[UIImageView class]])
{
UIImageView *imgView = (UIImageView*) objView;
if (imgView.tag > 0)
{
NSLog(#"%d",imgView.tag);
CGRect frame = imgView.frame;
frame.origin = CGPointMake(curXLoc, 0);
imgView.frame = frame;
curXLoc += (wScrollObjWidth);
}
}
}
Or if you want to grab only UIButtons,
for (UIButton *btnView in subviews)
{
if ([btnView isKindOfClass:[UIButton class]] && btnView.tag > 0)
{
NSLog(#"%d",btnView.tag);
CGRect frame = btnView.frame;
frame.origin = CGPointMake(curXLoc, 0);
btnView.frame = frame;
curXLoc += (wScrollObjWidth);
}
}

You want the button with tags greater than 0 right.. then why are you checking for [UIImageView class].. ?
your condition to find Buttons with tag greater than 0 should be :
if ([aView isKindOfClass:[UIButton class] && (aView.tag > 0)]) {
}
