'object' undeclared <first use in this function>
- by Mohit Deshpande
I am using Winchain to develop on my Windows 7 machine. Here is my code:
iPhoneTest.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface iPhoneTest : UIApplication {
UITextView *textview;
UIView *mainView;
}
@end
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;
}

mkdir -p $(dir $@)
$(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $@
clean:
echo rm -f $(OBJECTS_ABS)
echo rm -rf $(APP_ABS)
When I try to compile it with make, I get
iPhoneTest.m: In fucntion '-[iPhoneTest applicationDidFinishLaunching:]'
iPhoneTest.m:15: error: 'testView' undeclared <first use in this function>
iPhoneTest.m:15: error: <Each undeclared identifier is reported only once for each function it appears in>
Can anyone spot the problem?
