Iphone load XIB/m/h Problem
why does this not work:
- (void)viewDidLoad {
Login *neu =[[Login alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:neu animated:NO];
}
b开发者_高级运维ut this works
-(IBAction)dologin:(id)sender{
Login *neu =[[Login alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:neu animated:NO];
}
I wanted to load a specified class directly when one is loaded,...
I think it will work if you move [self presentModalViewController:neu animated:NO];
to viewDidAppear:
That way the modal view controller will pop up as soon as the view appears.
viewDidLoad:
isn't where you want to put up a modal view. It might be called after a low memory warning unloads your view controller, and then when the user navigates back to it, it will unexpectedly try to show a modal view. If you want to present something when the app launches, do so in applicationDidFinishLaunching:
in your app delegate, or set up a NSNotfication observer:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationDidFinishLaunching:) name:UIApplicationDidFinishLaunchingNotification object:nil];
and call presentModalViewController:
there.
