有需求就得 有方案，其实很简单，将webview当成一个cell，加入到tableview里面即可。
直接上代码
-(id)initWithReuseIdentifier:(NSString*)reuseIdentifier{
self = [super initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier];
if(self) {
self.selectionStyle = UITableViewCellSelectionStyleNone;
[selfinitLayout];
}
return self;
}
- (void)setSelected:(BOOL)selectedanimated:(BOOL)animated {
[supersetSelected:selectedanimated:animated];
// Configure the view for the selected state
}
+ (CGFloat)getCellHeight{
return tableHeight;
}
- (void) initLayout {
[self.contentView setBackgroundColor:PHWhiteColor];
self.contentView.clipsToBounds = YES;
[self setSelectionStyle:UITableViewCellSelectionStyleNone];
WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];
config.allowsInlineMediaPlayback = YES;
config.mediaPlaybackRequiresUserAction = false;
self.webView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, MAINSCREEN_WIDTH, 1) configuration:config];
self.webView.navigationDelegate = self;
self.webView.scrollView.scrollEnabled = NO;
[self.webView setBackgroundColor:PHWhiteColor];
[self.contentView addSubview:self.webView];
self.webView.translatesAutoresizingMaskIntoConstraints = NO;
[self.webView mas_makeConstraints:^(MASConstraintMaker *make) {
make.edges.equalTo(self.contentView).with.insets(UIEdgeInsetsMake(0,0,0,0));
}];
self.loadingView = [[PHLoadingView alloc] initWithFrame:self.contentView.bounds];
[self.contentView addSubview:self.loadingView];
self.firstLoading = YES;
}
- (void)loadH5Content:(NSString*)content {
if(content.hash==self.currentLoadContent.hash) {
return;
}
self.currentLoadContent = content;
NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
[self.webViewloadHTMLString:contentbaseURL:baseURL];
}
- (void)loadRequestWithUrl:(NSString *)url {
if([self.currentUrlisEqualToString:url]) {
return;
}
self.currentUrl= url;
NSURLRequest*request = [[NSURLRequestalloc]initWithURL:[NSURLURLWithString:url]];
[self.webViewloadRequest:request];
}
#pragma mark - WKWebViewDelegate
-(void)webView:(WKWebView*)webViewdecidePolicyForNavigationAction:(WKNavigationAction*)navigationActiondecisionHandler:(void(^)(WKNavigationActionPolicy))decisionHandler{
decisionHandler(WKNavigationActionPolicyAllow);
}
- (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation{
//开启加载效果
if (self.firstLoading) {
self.firstLoading=NO;
[self.loadingViewstartLoading];
}
}
- (void)webView:(WKWebView*)webViewdidFinishNavigation:(WKNavigation*)navigation{
//关闭加载效果
[self.loadingView stopLoading];
//不限制高度
[webViewevaluateJavaScript:@"document.body.offsetHeight"completionHandler:^(id_Nullabledata,NSError*_Nullableerror) {
if(!error) {
tableHeight= [datadoubleValue] +22.0f;
dispatch_async(dispatch_get_main_queue(), ^{
if(self.resetHeightBlock) {
self.resetHeightBlock(tableHeight);
}
});
}
}];
}
- (void)webView:(WKWebView*)webViewdidFailProvisionalNavigation:(WKNavigation*)navigationwithError:(NSError*)error{
//关闭加载效果
[self.loadingViewstopLoading];
}
- (void)dealloc
{
_webView.navigationDelegate = nil;
}
最关键的是拿到webview计算好的高度，然后回调给外面。然后刷新tableview即可
