copied!<p>I am creating a custom view that will act like a footer bar so I can pass in several views rather than using IB to add etc saving time and to learn more coding.</p> <p>My class first creates the background, then I add a UIButton to this, but for some reason the text is not showing and also the click is not firing.</p> <p>Custom class h file:</p> <pre><code> @interface menuViewone : UIView { IBOutlet UIView *menuback; } -(void)nextPage; -(void)menubackground; -(void)nextButton; </code></pre> <p>My custom class m file:</p> <pre><code> -(void)nextPage{ NSLog(@"Next Page Clicked"); } - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code } return self; } -(void)menubackground{ NSLog(@"Menu Background Loaded"); menuback = [[UIView alloc] initWithFrame:CGRectMake(0, 410, 320, 50)]; [menuback setBackgroundColor:[UIColor yellowColor]]; [self addSubview:menuback]; [menuback release]; [self nextButton]; } -(void)nextButton{ NSLog(@"Create Next Button"); UIButton *nextBtn = [UIButton buttonWithType:UIButtonTypeCustom]; nextBtn.frame = CGRectMake(0, 410, 60, 50); [nextBtn setBackgroundColor:[UIColor redColor]]; nextBtn.titleLabel.text = @"next"; nextBtn.titleLabel.textColor = [UIColor blackColor]; [nextBtn setTitle:@"Next" forState:UIControlStateNormal]; [nextBtn addTarget:self action:@selector(nextPage:) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:nextBtn]; } </code></pre> <p>I am calling it in my main m file using:</p> <pre><code> #import "menuViewone.h" ....... - (void)viewDidLoad { menuViewone *menu = [[menuViewone alloc] init]; [menu menubackground]; [self.view addSubview:menu]; [menu release]; [super viewDidLoad]; } </code></pre> <p>So at the moment I get a yellow footer background with a red button to the left, but no action or label</p> <p>1: whats going on? 2: am I doing this right?</p> <p><strong>UPDATE</strong> I have solved the issue of the text not showing which was when I was releasing the button which would auto release as mentioned below. </p> <p>So now my only issue is that the click event is not working, and I do not get my NSLog output from the -(void)nextPage{.. method.</p> <p>Here is the test one I created:</p> <pre><code> UIButton *nextBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [nextBtn setFrame:CGRectMake(0, 100, 80,40)]; [nextBtn setTitle:@"Button Title" forState:UIControlStateNormal]; [nextBtn.titleLabel setFont:[UIFont boldSystemFontOfSize:10]]; [nextBtn addTarget:self action:@selector(nextPage) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:nextBtn]; </code></pre> <p>but it seems as if the [nextBtn addTarget:self action:@selector(nextPage:) forControlEvents:UIControlEventTouchUpInside];</p> <p>is not firing?</p> <p><strong>ANOTHER UPDATE:</strong></p> <p>I have tried the following piece of code on the root/ my view Controller.</p> <p>viewController.h - (void)nextPage: (id)sender;</p> <p>viewController.m</p> <pre><code> -(void)nextPage: (id)sender { NSLog(@"Next Page Clicked"); } - (void)viewDidLoad { CGRect buttonFrame = CGRectMake( 10, 280, 100, 30 ); UIButton *button = [[UIButton alloc] initWithFrame: buttonFrame]; [button setTitle: @"My Button" forState: UIControlStateNormal]; [button setTitleColor: [UIColor redColor] forState: UIControlStateNormal]; [self.view addSubview: button]; [button addTarget: self action: @selector(nextPage:) forControlEvents: UIControlEventTouchDown]; ..... </code></pre> <p>And when I tried this the clicked method worked.</p> <p>So it must be something to do with my custom class view and the setting of my button as if its not recognised it??</p> <p>Thanks Si</p>
