IOS:黑色狀態列 圓角內容區

1.項目中引用QuartzCore.framework

2.在AppDelegate.m檔案中引用QuartzCore.h庫

#import <QuartzCore/QuartzCore.h>

3.在application: didFinishLaunchingWithOptions:方法的return YES語句前添加以下代碼

UIApplication *app = [UIApplication sharedApplication];[app setStatusBarStyle: UIStatusBarStyleBlackOpaque];self.window.rootViewController.view.layer.cornerRadius = 5;self.window.rootViewController.view.layer.masksToBounds = YES;

4. 整體代碼如下:

#import "AppDelegate.h"#import <QuartzCore/QuartzCore.h>@implementation Corner_TestAppDelegate@synthesize window=_window;@synthesize viewController=_viewController;- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{         self.window.rootViewController = self.viewController;    [self.window makeKeyAndVisible];        UIApplication *app = [UIApplication sharedApplication];    [app setStatusBarStyle: UIStatusBarStyleBlackOpaque];    self.window.rootViewController.view.layer.cornerRadius = 5;    self.window.rootViewController.view.layer.masksToBounds = YES;        return YES;}
