Question

一直试图在一行代码中找到错误。返回已注释掉的预期标识符错误。

你能帮我找到错误吗？谢谢。

抱歉代码格式不正确;不知道如何在这里得到它。

   #import "BIDAppDelegate.h"
   #import "BIDSwitchViewController.h"

   @implementation BIDAppDelegate

   @synthesize window = _window;
   @synthesize switchViewController;

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary    *)launchOptions
    {
        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
        // Override point for customization after application launch.
        self.switchViewController = [[BIDSwitchViewController alloc]

                                 initWithNibName:@"Switch View" 
    bundle:nil];
        UIView *switchView = self.switchViewController.view;
        CGRect switchViewFrame = switchView.frame;
        switchViewFrame.origin.y += [[UIApplication sharedApplication].statusBarFrame.size.height; //    Expected identifier

    switchView.frame = switchViewFrame;
                                     [self.window addSubview:switchView];

        self.window.backgroundColor = [UIColor whiteColor];
        [self.window makeKeyAndVisible];
        return YES;
    }

Answer 1

你有一个额外的[在违规声明的开头。：[[UIApplication sharedApplication]应为[UIApplication sharedApplication]

要格式化代码，将其粘贴，选择它并按问题编辑器顶部的{}按钮。

Answer 2

Cnange该行：

switchViewFrame.origin.y += [UIApplication sharedApplication].statusBarFrame.size.height;

预期的标识符
