Iphone '；对象'；未申报<；首次在此功能中使用>；

我正在使用Winchain在我的Windows7机器上开发。这是我的代码：
iPhoneTest.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>


@interface iPhoneTest : UIApplication {
    UITextView *textview;
    UIView *mainView;
}

@end

---

有人能发现问题吗？

标题声明了

textview

（小写），但实现引用了

textview

（camelCase）。标识符区分大小写。

在

.h

中是

textview

，但

.m

中是

，

.h

中是

你是指“textview”还是错误真的是说“testView”？你是指“textview”还是错误真的说“testView”“testView”？这就像第五个类似的问题，有相同的问题和答案。这是一种集合解析器/词法分析器/类型检查器：）这就像第五个类似的问题，有相同的问题和答案。还有一种集体解析器/词法分析器/类型检查器：）
