IOS:EmptyProject

새로운 빈 프로젝트(Empty Project)에 대한 분석.

  • main.m: 최초로 실행되는 파일. 
#import <UIKit/UIKit.h>
#import "SampleAppDelegate.h"

int main(int argc, char * argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([SampleAppDelegate class]));
    }
}
  • AppDelegate 클래스 선언부 코드는 아래와 같다. 
#import <UIKit/UIKit.h>

@interface SampleAppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@end
  • AppDelegate 클래스 구현부 코드는 아래와 같다. 
#import "SampleAppDelegate.h"

@implementation SampleAppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application { }
- (void)applicationDidEnterBackground:(UIApplication *)application { }
- (void)applicationWillEnterForeground:(UIApplication *)application { }
- (void)applicationDidBecomeActive:(UIApplication *)application { }
- (void)applicationWillTerminate:(UIApplication *)application { }
@end
