Guys, I'm not able to understand the problem.
An UIView can't be the subview in 2 different hierarchy. It would says that it has 2 or more superview. As you know instead, an UIView has just 1 superview..1 parent..and it can stay just in 1 hierarchy.

So of what we are talking about? About the CLASS? Or what? Someone have understood the question?

Completely wrong.
You are considering just direct subviews of the view..what if you have:

view -> view -> view -> VIEW_TO_FIND

you have to edit your code to go in depth recursively.

Many of these solution are really redundant. First of all to check if the lengths differ for more than 1 it is sufficient use the absolute value: `ABS(len1 - len2) > 1`. Then there is just a check to do, remembering if the we have already used "our change to wrong" and increment the correct index:

- (BOOL)oneEditAPartFromString:(NSString *)string1 andString:(NSString *)string2 {
    
    		int len1 = [string1 length], len2 = [string2 length];
    
    		if (ABS(len1 - len2) > 1)
        		return NO;
    
    		BOOL errorAvailable = YES;
    		int i = 0, j = 0;
    
    		while (i < len1 && j < len2) {
        
        		if ([string1 characterAtIndex:i] != [string2 characterAtIndex:j]) {
          			if (!errorAvailable)
                			return NO;
            
            			errorAvailable = NO;
            
           			 if (len1 == len2) {
                			++i;
                			++j;
            			} else if(len1 > len2) {
             			   	++i;
           			} else {
               				++j;
           			}
        		} else {
           			++i;
            			++j;
        		}
   	 	}
    
    		return YES;
	}
