viewDidAppear 未调用

我添加了 tabbarcontroller、setViewControllers 用于提供 uiviewcontroller 数组。为此 viewContollers 调用 viewDidLoad，但不会调用 viewDidAppear 和 viewWillAppear。我写的代码


- (void)loadView {
 printf("*********\n  loadView  \n********* ");
 UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
 contentView.backgroundColor = [UIColor whiteColor];
 self.view = contentView;
 [contentView release];
 UITabBarController *tabbar = [[UITabBarController alloc] init];
 tabbar.view.frame = CGRectMake(0, 0, 320, 460);
 piechartViewController *pr=[[piechartViewController alloc]init];
 pr.tagInAction=1;
 pr.title=@"Type";
 pr.tabBarItem.image=[UIImage imageNamed:@"trend.png"];
 pr.sDate=sDate;
 pr.nDate=nDate;
 piechartViewController *pr1=[[piechartViewController alloc]init];
 pr1.title=@"category";
 pr1.tagInAction=4;
 pr1.sDate=sDate;
 pr1.nDate=nDate;
 piechartViewController *pr2=[[piechartViewController alloc]init];
 pr2.title=@"paidWith";
 pr2.tagInAction=3;
 pr2.sDate=sDate;
 pr2.nDate=nDate;
 [tabbar setViewControllers:[NSArray arrayWithObjects:pr,pr1,pr2,nil]];
 [self.view addSubview:tabbar.view ];
 [pr release];
 [pr1 release];
 [pr2 release];
}

原文

I have added tabbarcontroller, setViewControllers used for providing array of uiviewcontroller. viewDidLoad is called for this viewContollers but not viewDidAppear neither viewWillAppear.
the code I have written


- (void)loadView {
 printf("*********\n  loadView  \n********* ");
 UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
 contentView.backgroundColor = [UIColor whiteColor];
 self.view = contentView;
 [contentView release];
 UITabBarController *tabbar = [[UITabBarController alloc] init];
 tabbar.view.frame = CGRectMake(0, 0, 320, 460);
 piechartViewController *pr=[[piechartViewController alloc]init];
 pr.tagInAction=1;
 pr.title=@"Type";
 pr.tabBarItem.image=[UIImage imageNamed:@"trend.png"];
 pr.sDate=sDate;
 pr.nDate=nDate;
 piechartViewController *pr1=[[piechartViewController alloc]init];
 pr1.title=@"category";
 pr1.tagInAction=4;
 pr1.sDate=sDate;
 pr1.nDate=nDate;
 piechartViewController *pr2=[[piechartViewController alloc]init];
 pr2.title=@"paidWith";
 pr2.tagInAction=3;
 pr2.sDate=sDate;
 pr2.nDate=nDate;
 [tabbar setViewControllers:[NSArray arrayWithObjects:pr,pr1,pr2,nil]];
 [self.view addSubview:tabbar.view ];
 [pr release];
 [pr1 release];
 [pr2 release];
}

嘿，您确定要使用 loadView 而不是使用 viewDidLoad 吗？
当你调用这个视图控制器时，你可以粘贴代码吗？
顺便说一句，“self.view = contentView”？也许 [self.view addSubview:contentView] 听起来更好，你不觉得吗？
