Question

I having scroolViewController having UIImageView and UITextView.so how we fatch the UItextView text and image of UIImage.it gives error…

for(UIView *subview2 in [scroolViewController subviews])
{            
    NSLog(@"-----%@",subview2); 
    if([subview2 isKindOfClass:[UIImageView class]])
    {
        [dictImages setValue:subview2.image forKey:@"positionY"];
    }
    if(subview2 isKindOfClass:[UITextView class])
    {
        [dicText setValue:subview3.text forKey:@"text"];
    }
}

Or when we writhe this

for(UIView *subview2 in [scroolViewController subviews])
{            
     NSLog(@"-----%@",subview2); 
}

then console gives:

-----<UITextView: 0xb8791d0; frame = (5 10; 285 340); text = ''; clipsToBounds = YES; userInteractionEnabled = NO; layer = <CALayer: 0xb860a30>; contentOffset: {0, 0}>

-----<UIImageView: 0xb0c9d10; frame = (134 118; 100 100); opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0xb0c8600>>

so how we save text and image dictionary from getting subviews…????

Answer 1

To fix the compiler error, do:

[dictImages setValue:((UIImageView*)subview2).image forKey:@"positionY"];

Since you’ve already checked that it’s the right class, casting it is fine.

Is dictImages an NSMutableDictionary?
