'object'undeclared <이 기능에서 처음 사용>

Question

Winchain을 사용하여 Windows 7 컴퓨터에서 개발 중입니다. 여기 내 코드입니다 :
iPhoneTest.h

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


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

@end 

는 iPhoneTest.m

#import "iPhoneTest.h" 
#import <UIKit/UIKit.h> 
#import <Foundation/Foundation.h> 
#import <CoreFoundation/CoreFoundation.h> 


@implementation iPhoneTest 
-(void)applicationDidFinishLaunching:(id)unused { 
    UIWindow *window; 
    struct CGRect rect = [UIHardware fullScreenApplicationContentRect]; 
    rect.origin.x = rect.origin.y = 0.0f; 

    window = [[UIWindow alloc] initWithContentRect: rect]; 
    mainView = [[UIView alloc] initWithFrame: rect]; 
    textView = [[UITextView alloc] init]; 
    [textView setEditable:YES]; 
    [textView setTextSize:14]; 

    [window orderFront: self]; 
    [window makeKey: self]; 
    [window _setHidden: NO]; 
    [window setContentView: mainView]; 
    [mainView addSubview:textView]; 

    [textView setText:@"Hello World"]; 

} 
@end 

main.m

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


int main(int argc, char *argv[]) { 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    int ret = UIApplicationMain(argc, argv, [iPhoneTest class]); 
    [pool release]; 
    return ret; 
}

iPhoneTest.m: In function '-[iPhoneTest applicationDidFinishLaunching:]' 
iPhoneTest.m:15: error: 'textView' undeclared <first use in this function> 
iPhoneTest.m:15: error: <Each undeclared identifier is reported only once for each function it appears in> 

사람이 문제를 발견 할 수거야?

Answer 1

헤더는 textview (소문자)을 선언하지만 구현은 textView (camelCase)을 나타냅니다. 식별자는 대소 문자를 구분합니다.

Answer 2

당신이 '텍스트 뷰'를 의미했다
