pod 'DYFProgressView', '~> 1.1.0'
Or
# Installs lastest version.
pod 'DYFProgressView'
- 实例化
// Lazy load
- (DYFWebProgressView *)progressView {
if (!_progressView) {
CGFloat w = self.navigationBar.bounds.size.width;
CGFloat h = 3.f;
CGFloat x = 0.f;
CGFloat y = self.navigationBar.bounds.size.height - h;
_progressView = [[DYFWebProgressView alloc] initWithFrame:CGRectMake(x, y, w, h)];
_progressView.lineWidth = 3.f;
_progressView.lineColor = [UIColor colorWithRed:RGB_V(10)
green:RGB_V(115)
blue:RGB_V(255)
alpha:1];
}
return _progressView;
}
- (UINavigationBar *)navigationBar {
return self.navigationController.navigationBar;
}- 添加到父视图
// 在开始加载进度前，调用它
- (void)loadView {
[super loadView];
[self addProgressView];
}
// 添加到父视图。
- (void)addProgressView {
if (!_progressView) {
[self.navigationBar addSubview:self.progressView];
}
}
- 开始加载进度
[self.progressView startLoading];
- 结束加载进度
[self.progressView endLoading];
- Invoked when a main frame navigation starts.
- (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation {
// didStartProvisionalNavigation.
NSURL *aURL = [webView.URL copy];
NSLog(@"%s url: %@", __FUNCTION__, aURL);
[self.progressView startLoading];
}
- Invoked when a server redirect is received for the main frame.
- (void)webView:(WKWebView *)webView didReceiveServerRedirectForProvisionalNavigation:(WKNavigation *)navigation {
// didReceiveServerRedirectForProvisionalNavigation.
NSLog(@"%s url: %@", __FUNCTION__, webView.URL);
}
- Invoked when content starts arriving for the main frame.
- (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation {
NSLog(@"%s", __FUNCTION__);
}
- Invoked when a main frame navigation completes.
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation {
NSLog(@"%s", __FUNCTION__);
[self.progressView endLoading];
[self setupNavigationItemTitle];
}
- Invoked when an error occurs while starting to load data for the main frame.
- (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error {
if (!error) { return; }
NSString *errMessage = [NSString stringWithFormat:@"%zi, %@", error.code, error.localizedDescription];
NSLog(@"%s [error]: %@", __FUNCTION__, errMessage);
[self.progressView endLoading];
}
- Invoked when an error occurs during a committed main frame navigation.
- (void)webView:(WKWebView *)webView didFailNavigation:(WKNavigation *)navigation withError:(NSError *)error {
if (!error) { return; }
NSString *errMessage = [NSString stringWithFormat:@"%zi, %@", error.code, error.localizedDescription];
NSLog(@"%s [error]: %@", __FUNCTION__, errMessage);
[self.progressView endLoading];
}
- Decides whether to allow or cancel a navigation.
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
// decidePolicyForNavigationAction.
[self setupNavigationItemTitle];
NSURL *aURL = [navigationAction.request.URL copy];
NSString *aUrl = aURL.absoluteString;
NSLog(@"%s url: %@", __FUNCTION__, aUrl);
if (![aUrl isEqualToString:@"about:blank"]) {}
// Method NO.1: resolve the problem about '_blank'.
//if (navigationAction.targetFrame == nil) {
//NSLog(@"- [webView loadRequest:navigationAction.request]");
//[webView loadRequest:navigationAction.request];
//}
decisionHandler(WKNavigationActionPolicyAllow);
}
- Creates a new web view. Resolves the problem about '_blank'.
// Method NO.2: resolve the problem about '_blank'.
- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures {
// createWebViewWithConfiguration.
NSURL *aURL = [navigationAction.request.URL copy];
