copied!<p>In order to get the contents of a xib file you've got to load it first sending <code>loadNibNamed:owner:options:</code> message to NSBundle class.</p> <p>Consider you have a UIView subclass named CustomView and CustomView.xib file. In the xib file each view has a tag. Your .h file would look like:</p> <pre><code>@interface CustomView : UIView @property (nonatomic, assign) UILabel *someTextLabel; //use assign in order to not to override dealloc method @end .m @implementation CustomView - (id)init { self = [super init]; if (self) { NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomView" owner:nil options:nil]; [self addSubview:[topLevelObjects objectAtIndex:0]]; //this object is a CustomView.xib view self.someTextLabel = (UILabel *)[self viewWithTag:5]; //consider you have a UILabel on CustomView.xib that has its tag set to 5 } return self; } @end </code></pre> <p>This is about how to use .xibs for your custom UIView subclasses. If your app is like a chat then you'll have to add them programmatically.</p> <p>As for the best way to send messages between two custom views, you'll have to create a weak reference to each other in each of them.</p> <p>in one</p> <pre><code>@property (nonatomic, assign) CustomView *customView; </code></pre> <p>in another</p> <pre><code>@property (nonatomic, assign) AnotherCustomView *anotherCustomView; </code></pre> <p>and just send them messages when some even happens</p> <pre><code>- (void)buttonPressed { [customView handleButtonPressedEvent]; } </code></pre> <p>Let me know if this is clear.</p>
