我想用我自己的控制器在uiviewcontrollers之間進行導航。所以就像我可以在我的意見之間進行自定義轉換。以這種方式切換UIViewController是否正確?
我做了一些工作,但我不確定它是否正確?以後會不會有與記憶有關的問題?......我不確定一切都以正確的方式被釋放。
感謝您的幫助!
這裏是我的代碼:
在我的AppDelegate,在啓動時:
self.rootVC = [[[MenuView alloc] initWithNibName:@"MenuView" bundle:nil] autorelease];
[self.window addSubview:self.rootVC.view];
在我的AppDelegate,用於切換UIViewController中的方法:
-(void) changeRootController: (NSString*) ctrlName{
UIViewController *oldVC = self.curVC;
UIViewController *newVC;
if(ctrlName == @"Studio"){
newVC = [[StudioView alloc] initWithNibName:@"StudioView" bundle:nil];
}
else if(ctrlName == @"Menu"){
newVC = [[MenuView alloc] initWithNibName:@"MenuView" bundle:nil];
}
self.curVC = newVC;
[UIView transitionWithView:self.window
duration:1.0
options:UIViewAnimationOptionCurveEaseIn
animations:^{
newVC.view.transform = CGAffineTransformConcat(newVC.view.transform, CGAffineTransformMakeTranslation(-1024, 0));
[self.rootVC.view addSubview:newVC.view];
newVC.view.transform = CGAffineTransformConcat(newVC.view.transform, CGAffineTransformMakeTranslation(1024, 0));
oldVC.view.transform = CGAffineTransformConcat(oldVC.view.transform, CGAffineTransformMakeTranslation(1024, 0));
}
completion:^(BOOL finished){
if(finished){
[oldVC release];
}
}
];
}
我切換在我的UIViewController視圖如下:
AppDelegate *ad = (AppDelegate*)[[UIApplication sharedApplication] delegate];
[ad changeRootController:@"Studio"];
爲什麼不使用ARC? – Stavash 2012-07-23 12:10:35
