    <p>Here's my predicament. Bare with me as I'm a bit of a noob when it comes to Objective-C and iOS programming. I've got a <code>leftBarButtonItem</code> (using a custom view) that's acting as a replacement for a back button (as custom views can't be used on <code>backBarButtonItem</code>). I've also got a <code>rightBarButtonItem</code> (also using a custom view) and a custom titleView.</p> <p>Everything works fine and dandy when the <code>leftBarButtonItem</code> is smaller than a certain width. The <code>rightBarButtonItem</code> can be huge and the titleView will resize and truncate to fit the available space, which is exactly how it should be, and how I want it.</p> <p>However, with the same dimensions reversed (<code>rightBarButtonItem</code> smaller than a certain width and <code>leftBarButtonItem</code> huge), the <code>leftBarButtonItem</code> disappears entirely, and the <code>titleView</code> stretches to fit the entire space that previously would have held both the <code>leftBarButtonItem</code> and the <code>titleView</code>.</p> <p>I tried swapping the custom views to see if it was something I had done, but the same problem persisted with the views swapped, again only on the <code>leftBarButtonItem</code>. I also tried using a regular title, without the custom <code>titleView</code>, to no avail.</p> <p>In the documentation for <code>UINavigationItem</code>, under <code>leftBarButtonItems</code>, it notes that "If there is not enough room to display all of the items in the array, those that would overlap the title view (if present) or the buttons on the right side of the bar are not displayed." However, there should be more than enough room to fit both buttons and the title, as demonstrated by having a huge <code>rightBarButtonItem</code> and a truncated title. Not to mention, there is only a single <code>leftBarButtonItem</code>, not multiple, and I need it to appear to replace the back button functionality.</p> <p>Any ideas on how to stop this from happening? Here's a snippet of the code I'm using:</p> <pre><code>self.navigationItem.titleView = [[TitleView alloc] initWithFrame:CGRectMake(0, 0, 220, 44)]; self.navigationItem.titleView.backgroundColor=[UIColor clearColor]; FollowButton *follow = [[FollowButton alloc] initWithFrame:CGRectMake(0, 0, 62, 34)]; UIBarButtonItem *followButton = [[UIBarButtonItem alloc] initWithCustomView:follow]; self.navigationItem.rightBarButtonItem = followButton; BackButton *back = [[BackButton alloc] initWithFrame:CGRectMake(0, 0, 108, 34)]; [back addTarget:self.navigationController action:@selector(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:back]; self.navigationItem.leftBarButtonItem = backButton; </code></pre>

    1. COIt looks like your TitleView is too big. Just step in to the code and see how big screen is, and your question will be answered. [UIScreen mainScreen] bounds].size.width

    2. COThat doesn't make sense though, if I leave the leftBarButtonItem a fairly small size, and make the rightBarButtonItem huge, to the point where it's filling most of the navigation bar, the titleView gets auto-resized and the text gets truncated (as expected) to fit in the tiny remaining area. If I do the opposite, with the rightBarButtonItem small and the leftBarButtonItem huge, the leftBarButtonItem gets hidden. I would expect that the titleView would resize to fit between them.

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.
