似乎无法解决这个问题。知道需要改变什么吗?我正在使用Xcode 4.2。
错误: AppDelegate.m:23:6:错误:接收器类型'AppDelegate'例如消息未声明带有选择器'setupHUD'的方法[4]
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
LoginViewController *loginVC = [[LoginViewController alloc] init];
UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:loginVC];
navCon.navigationBarHidden = YES;
self.window.rootViewController = navCon;
[self setupHUD];
[self.window makeKeyAndVisible];
return YES;
}
- (void) setupHUD
{
//setup progress hud
self.HUD = [[MBProgressHUD alloc] initWithFrame:self.window.bounds];
[self.window addSubview:self.HUD];
self.HUD.dimBackground = YES;
self.HUD.minSize = CGSizeMake(150.f, 150.f);
self.HUD.delegate = self;
self.HUD.isCancelButtonAdded = YES;
self.HUD.labelText = @"Loading";
}
答案 0 :(得分:1)
Prior to Xcode 4.3,您需要转发在同一@implementation
块内调用的声明方法,因此请确保将setupHUD
的声明添加到类扩展(内部声明列表)中以@interface AppDelegate ()
)开头的AppDelegate.m,或AppDelegate.h中的@interface
块。
例如,在AppDelegate.m中:
@interface AppDelegate ()
// Other declarations...
- (void)setupHUD;
@end
或者在AppDelegate.h中:
@interface AppDelegate : NSObject <UIApplicationDelegate>
// Other declarations
- (void)setupHUD;
@end
