一直以来只用过UIWebView,看别人源码项目用到了WKWebView,这里记录一下,毕竟iOS8建议使用WKWebView了.
- (instancetype)initWithUrl:(NSString *)url {
if (self = [super init]) {
self.url = url;
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
NSURL *URL = [NSURL URLWithString:[self.url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[self.webView loadRequest:[NSURLRequest requestWithURL:URL]];
}
- (WKWebView *)webView {
if (!_webView) {
WKWebView *wkWebView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, kScreenWidth, kScreenHeight - 64)];
[self.view addSubview:wkWebView];
_webView = wkWebView;
wkWebView.UIDelegate = self;
wkWebView.navigationDelegate = self;
wkWebView.opaque = NO;
wkWebView.backgroundColor = self.view.backgroundColor;
}
return _webView;
}

}
