[iOS]黑色状态栏 圆角内容区

1.项目中引用QuartzCore.framework

2.在AppDelegate.m文件中引用QuartzCore.h库

#import <QuartzCore/QuartzCore.h>

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

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

4. 整体代码如下:

#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;
}
