Discussion 1: le signal reçu Programm: "SIGABRT"

Question

Im essayant de construire une application facile avec vue swiching et UIWebView il a travaillé jusqu'à ce que je l'ai écrit UIWebView

-(IBAction)pushButton { 

    TermineViewController *screen = [[TermineViewController alloc] initWithNibName:nil bundle:nil]; 
    screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
    [self presentModalViewController:screen animated:YES]; thread 1: program receved signal: "SIGaBRT" 
    [screen release]; 
} 

-(IBAction)pushButton2 { 

    SpeiseplanViewController *screen = [[SpeiseplanViewController alloc] initWithNibName:nil bundle:nil]; 
    screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
    [self presentModalViewController:screen animated:YES]; 
    [screen release];

Answer 1

Vous n'êtes pas en train de créer une vue.

-(void)viewDidLoad { 
    [super viewDidLoad]; 
    webView = [[UIWebView alloc] initWithFrame:aRect]; //<-------- 
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.landheim-schondorf.de/news/"]]]; 
    [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(checkLoad) userInfo:nil repeats:YES]; 
    [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(checkNotLoad) userInfo:nil repeats:YES]; 

} 

En outre, vous devez libérer webView dans dealloc. Et vous devriez vous sentir à l'aise avec les propriétés.
