iPhone tabBar - 我应该如何实现模态视图，以便每次选择选项卡时都会出现？

Question

您能告诉我实现模态视图的最佳方法，以便每次选择/按下某个选项卡时都会出现模态视图吗？因为我目前的代码方式导致所有后续选择/推送什么都不做。

#import <UIKit/UIKit.h>

@interface SecondViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{
    UIImage *image;
    IBOutlet UIImageView *imageView;
}

@end

---

#import "SecondViewController.h"

@implementation SecondViewController

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    image = [info objectForKey:UIImagePickerControllerOriginalImage];
    imageView.image = image;
    [self dismissModalViewControllerAnimated:YES];
}


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
    [super viewDidLoad];
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

...
@end
