添加uibarbutton爲ZBarReaderViewController

我對ZBarReader工作，什麼我有這麼遠，現在是添加uibarbutton爲ZBarReaderViewController

ZBarReaderViewController *controller = [[ZBarReaderViewController alloc] init]; 
controller.navigationController.navigationBarHidden = NO; 
// Add Edit button to the right and handle click event UIBarButtonItem *manualButton = [[UIBarButtonItem alloc] initWithTitle:@"Manual" style:UIBarButtonItemStyleBordered target:self action:@selector(EditMode:)]; 
[controller.navigationItem setRightBarButtonItem:manualButton]; 
controller.readerDelegate = self; 
[self presentModalViewController:controller animated:YES];

我的問題是，我們可以這樣這樣的事情上面：設置工具欄可見，並添加按鈕就可以了ZBarReaderViewController。

是的，你先設置一些屬性爲您ZBarReaderViewController

self.zReader.showsCameraControls = NO; 
self.zReader.showsZBarControls=NO;

然後，你必須設置自定義cameraOverlayView，例如這個設置UIToolBar用左按鈕關閉選擇器和UISwitch控制在flashMode：

self.zReader.cameraOverlayView=[self setOverlayPickerView]; 

- (UIView *)setOverlayPickerView{ 
    UIView *v=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; 
    [v setBackgroundColor:[UIColor clearColor]]; 
    UIToolbar *myToolBar = [[UIToolbar alloc] init]; 
    UIBarButtonItem *backButton=[[UIBarButtonItem alloc] initWithTitle:@"back" style:UIBarButtonItemStyleBordered target:self action:@selector(dismissOverlayView:)]; 
    UISwitch *sw=[[UISwitch alloc] init]; 
    [sw setOn:NO]; 
    UIBarButtonItem *switchButton=[[UIBarButtonItem alloc] initWithCustomView:sw]; 
    UIBarButtonItem *fixed=[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; 
    [sw addTarget:self action:@selector(handleSwitchFlash:) forControlEvents:UIControlEventValueChanged]; 
    [myToolBar setItems:[NSArray arrayWithObjects:backButton,fixed,switchButton,nil]]; 
    [myToolBar setBarStyle:UIBarStyleDefault]; 
    CGRect toolBarFrame; 
    toolBarFrame = CGRectMake(0, 436, 320, 44); 
    [myToolBar setFrame:toolBarFrame]; 
    [v addSubview:myToolBar]; 
    return v; 
} 

- (void)dismissOverlayView:(id)sender{ 
    [self dismissModalViewControllerAnimated: YES]; 
}

它確實幫助了我。我試過了，它工作。你知道我們如何從nib加載視圖而不是編程呢？ – tranvutuan 2012-04-14 18:47:54

您可以創建一個普通的UIViewController（帶有一個xib）並將其視圖傳遞給'cameraOverlayView'。 – Mat 2012-04-14 19:02:18

我剛剛給了它一個嘗試..請看看我的另一篇文章在[鏈接]（http://stackoverflow.com/questions/10156930/customization-of-the-camera-overlay） – tranvutuan 2012-04-14 20:06:07

此外@Mat答案，應該添加 [self.zReader.view setFrame:[UIScreen mainScreen].bounds]; befo re self.zReader.cameraOverlayView=[self setOverlayPickerView];

因爲默認情況下，self.zReader的大小是（320,480）。

順便說一句，如果沒有必要兼容iOS6.0，你可以使用[AVCaptureDevice]：https://developer.apple.com/library/mac/documentation/AVFoundation/Reference/AVCaptureDevice_Class/Reference/Reference.html
