私は検索して検索しましたが、この問題に関するトピックはたくさんありますが、問題を解決するのに関連するトピックが見つかりません。誰かが見てくれたら：
私はxcode 4.6を使用しています
int retVal の main.m ファイルでエラーが発生しています
int main(int argc, char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil);
[pool release];
return retVal;
}
私の ReaderSampleViewController.h ファイルは次のようになります。
@interface ReaderSampleViewController

// ADD: delegate protocol

UIImageView *resultImage;
UITextView *resultText;
}
@property (nonatomic, retain) IBOutlet UIImageView *resultImage;

- (IBAction) scanButtonTapped;
@end
ReaderSampleViewController.m ファイルは次のようになります。

ZBarReaderViewController *reader = [ZBarReaderViewController new];

if else cgRect ディメンションは以前は正常に機能していましたが、おそらく誤って何かを削除したか、このエラーに陥り、アプリケーションがロード時に一時停止する原因となるコンマをどこかに配置した可能性があります。以下は、それが返すエラーです。

申し訳ありませんが、アプリ開発は比較的新しいため、さまざまなエラーを回避しようとして苦労しています。どんなアドバイスも素晴らしいでしょう
