    <p>Hey I'm very new to iPhone programming and I have been searching for hours both on this site and on google for the solution to my problem. Basically I am trying to make an app which selects a random string out of my plist and displays it into a text field. I have tried countless ways, but this way seems to work the best, however it still crashes when I press a button and gives me the error "EXC_ARITHMETIC" on the arc4random line. As well as this error, the NSLog(@"items: &amp;@", items) displays items: (null) in the log when i press the button. Any help or suggestions are GREATLY appreciated. P.S. items is an NSMutableArray I already set up in the .h file</p> <pre><code>-(IBAction)buttonPress { NSString* path = [[NSBundle mainBundle] pathForResource:@"ItemList" ofType:@"plist"]; items = [[NSMutableArray alloc]initWithContentsOfFile:path]; NSLog(@"items: %@", items); NSInteger randomIndex = arc4random() % [items count]; NSString* randomString = [items objectAtIndex:randomIndex]; textField.text = randomString; } </code></pre> <p>Here's the plist code</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt; &lt;plist version="1.0"&gt; &lt;dict&gt; &lt;key&gt;Array&lt;/key&gt; &lt;array&gt; &lt;string&gt;AAA&lt;/string&gt; &lt;string&gt;BBB&lt;/string&gt; &lt;string&gt;CCC&lt;/string&gt; &lt;string&gt;DDD&lt;/string&gt; &lt;string&gt;EEE&lt;/string&gt; &lt;string&gt;FFF&lt;/string&gt; &lt;string&gt;GGG&lt;/string&gt; &lt;string&gt;HHH&lt;/string&gt; &lt;string&gt;III&lt;/string&gt; &lt;string&gt;JJJ&lt;/string&gt; &lt;/array&gt; </code></pre> <p> </p> <p>Thanks guys again for all your help!</p>

    1. COIf `items` is `nil`, then your plist is very possibly an `NSDictionary` and not an `NSArray`....

    2. COHey thanks for the response. Turns out the plist was an NSDictionary, so I changed it to an NSArray. Still no dice. Same errors showing up as before.

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.
