    <p>I am pretty new to iPhone development and I am getting this error output. I know what is happening, I just don't know how to fix it.</p> <pre><code> Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[&lt;loginData 0x6b1c&gt; setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key UserEMailAddress.' </code></pre> <p>Basically I am using the XML parser and trying to store data into my created class 'loginData.' The first element I come to, is UserEMailAddress and the code is trying to store that value into the class variable UserEMailAddress of the same name. But its throwing that error.</p> <p>Obviously something went awry when I created my class. Somehow I guess things were not set up right and it can't input the data into the class. All I did to create loginData was do a file->new-> class object.</p> <p>Here is the class code.</p> <p>loginData.h</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; @interface loginData : NSObject{ NSString *UserEMailAddress; NSString *SessionUID; NSString *SessionExpirationUTCDT; } @property (nonatomic, retain) NSString *UserEMailAddress; @property (nonatomic, retain) NSString *SessionUID; @property (nonatomic, retain) NSString *SessionExpirationUTCDT; @end </code></pre> <p>loginData.m</p> <pre><code> #import "loginData.h" @implementation loginData @synthesize UserEMailAddress=_UserEMailAddress; @synthesize SessionUID=_SessionUID; @synthesize SessionExpirationUTCDT=_SessionExpirationUTCDT; @end </code></pre> <p>pretty simple stuff, nothing too complex.</p> <p>the last method accessed before the crash is in my XMLParser, which is..</p> <pre><code>- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if (!currentElementValue) { // init the ad hoc string with the value currentElementValue = [[NSMutableString alloc] initWithString:string]; } else { // append value to the ad hoc string [currentElementValue appendString:string]; } NSLog(@"Processing value for : %@", string); } </code></pre> <p>I'm sure I just made a small mistake in making my class, but I don't know what that would be. Thanks in advance.</p> <p>The only other method where it looks as if the variables are input to my class is this one.</p> <pre><code> - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"LoginResponse"]) { // We reached the end of the XML document return; } //if ([elementName isEqualToString:@"user"]) { // We are done with user entry – add the parsed user // object to our user array //[users addObject:user]; // release user object //[user release]; //user = nil; // } else { // The parser hit one of the element values. // This syntax is possible because User object // property names match the XML user element names [loginData setValue:currentElementValue forKey:elementName]; } currentElementValue = nil; } </code></pre>

    2. COYes. No change. I have heard 'clean' still leaves some things around unchanged but I doubt that would apply to this.

    3. COXcode will not use the variable `UserEMailAddress` you declared in the header, but will generate a iver called `_UserEMailAddress ` thus making your declaration of `UserEMailAddress` unused. Also Class names start capitols and properties do not, just the other way around then the way you did it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
