WKWebView 설정하기

iOS8이상 버전부터 지원

기존의 스크립트 해석 속도 향상등 UIWebView보다 개선사항이 많아 짐

아래와 같이 설정

- WebKit.framework 추가 후 Optional 설정

  (Deplyment Target이 8.0 일 경우, 그 이상 사용하는 경우는 Required로 해도 무방)

- 소스 적용

MainViewController.h

#import <WebKit/WebKit.h>

@interface MainViewController ()<WKUIDelegate, WKNavigationDelegate>

@end

MainViewController.m

- (void)viewDidLoad {

    [super viewDidLoad];

    WKWebView  *mainWebView = [[WKWebView alloc] initWithFrame:self.view.frame];

    mainWebView.UIDelegate = self;

    mainWebView.navigationDelegate = self;

    mainWebView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

    [self.view addSubview:mainWebView];

    NSURL *url = [NSURL URLWithString:@"http://www.naver.com"];

    NSMutableURLRequest *mutableRequest = [NSMutableURLRequest requestWithURL:url];

    

    [mainWebView loadRequest:mutableRequest];

}
