RootViewController;

@interface

AppDelegate

:

UIResponder

<UIApplicationDelegate>

@property

(strong,

nonatomic)

UIWindow

*window;

@property

(strong,

nonatomic)

RootViewController

*rootViewController;

@end在@implementation之前添加#import

"RootViewController.h"，在@implementation之后添加@synthesize

rootViewController;然后修改didFinishLaunchingWithOptions方法如下：view

source

print

?

-

(BOOL)application:(UIApplication

*)application

didFinishLaunchingWithOptions:(NSDictionary

*)launchOptions

{

self.window

=

[[UIWindow

alloc]

initWithFrame:[[UIScreen

mainScreen]

bounds]];

//

Override

point

for

customization

after

application

launch.

self.rootViewController

=

[[RootViewController

alloc]

initWithNibName:@"RootView"

bundle:nil];

UIView

*rootView

=

self.rootViewController.view;

CGRect

rootViewFrame

=

rootView.frame;

rootViewFrame.origin.y

+=

[UIApplication

sharedApplication].statusBarFrame.size.height;

rootView.frame

=

rootViewFrame;

[self.window

addSubview:rootView];

self.window.backgroundColor

=

[UIColor

whiteColor];

[self.window

makeKeyAndVisible];

return

YES;

}
