iphone - insertSubView：没有显示我的观点

我陷入了教程，试图用工具栏切换视图。我的代码构建正常，我发出一些警报，以检查工具栏是否正常工作，它是。但是我插入的子视图根本就没有显示出来。有人可以帮忙吗？

这是我的主控制器代码..

MainViewController.h是


#import 

@class FlavourPickerView;
@class ShakeView;
@class ResultsView;

@interface MainViewController : UIViewController {

    IBOutlet FlavourPickerView *flavourPickerView;
    IBOutlet ShakeView *shakeView;
    IBOutlet ResultsView *resultsView;
}

@property (retain,nonatomic) FlavourPickerView *flavourPickerView;
@property (retain,nonatomic) ShakeView *shakeView;
@property (retain,nonatomic) ResultsView *resultsView;

-(IBAction)loadFlavourPickerView:(id)sender;
-(IBAction)loadShakeView:(id)sender;
-(IBAction)loadResultsView:(id)sender;

-(void)clearView;

@end

这是MainViewController.m

#import "MainViewController.h"
#import "FlavourPickerView.h"
#import "ShakeView.h"
#import "ResultsView.h"

@implementation MainViewController

@synthesize flavourPickerView;
@synthesize shakeView;
@synthesize resultsView;


-(IBAction)loadFlavourPickerView:(id)sender{
 UIAlertView *alertDialog;
 alertDialog = [[UIAlertView alloc]
       initWithTitle:@"Flavour selected"
       message:@"Seems to work"
       delegate:nil
       cancelButtonTitle:@"OK!"
       otherButtonTitles:nil];
 [alertDialog show];
 [alertDialog release];

 [self clearView];
 [self.view insertSubview:flavourPickerView.view atIndex:10];
}


-(IBAction)loadShakeView:(id)sender{
 UIAlertView *alertDialog;
 alertDialog = [[UIAlertView alloc]
       initWithTitle:@"Shaker selected"
       message:@"Seems to work"
       delegate:nil
       cancelButtonTitle:@"OK!"
       otherButtonTitles:nil];
 [alertDialog show];
 [alertDialog release];

 [self clearView];
 [self.view insertSubview:shakeView.view atIndex:0];
}


-(IBAction)loadResultsView:(id)sender{
 UIAlertView *alertDialog;
 alertDialog = [[UIAlertView alloc]
       initWithTitle:@"Results selected"
       message:@"Seems to work"
       delegate:nil
       cancelButtonTitle:@"OK!"
       otherButtonTitles:nil];
 [alertDialog show];
 [alertDialog release];

 [self clearView];
 [self.view insertSubview:resultsView.view atIndex:0];

 }


-(void)clearView{
 if(flavourPickerView.view.superview){
  [flavourPickerView.view removeFromSuperview];
 }else if(shakeView.view.superview){
  [shakeView.view removeFromSuperview];
 }else{
  [resultsView.view removeFromSuperview];
 }
}


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
 [self loadFlavourPickerView:nil];
 [super viewDidLoad];
}


- (void)didReceiveMemoryWarning {
 // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

 // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
 // Release any retained subviews of the main view.
 // e.g. self.myOutlet = nil;
}


- (void)dealloc {
 [flavourPickerView release];
 [shakeView release];
 [resultsView release];
    [super dealloc];
}

@end

以下是其他一个视图的示例，从FlavourPickerView.h

开始


#import 


@interface FlavourPickerView : UIViewController {

}

@end

和FlavourPickerView.m

#import "FlavourPickerView.h"


@implementation FlavourPickerView

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (void)dealloc {
    [super dealloc];
}


@end

还有一个用于flavourPickerView的笔尖，我已将子视图添加到我的mainView中，其中Class设置为FlavourPickerView，nib名称为FlavourPickerView.xib。
