網上應該有很多相關的解決辦法，這種是調用官方的API， 所以從http直接轉https會容易點，而且要修改的地方不多，只需實現以下幾個代理方法就可以了，把返回的NSData類型數據 encoding 一下，然后 loadHTMLString 就行了，不多說，直接上代碼先：
@interface ViewController ()
<UIWebViewDelegate,NSURLConnectionDelegate,NSURLConnectionDataDelegate>
{
UIWebView *webView;
NSURLConnection *connenction;
NSMutableData *mutableData;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
webView.delegate = self;
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.baidu.com"]];
[webView loadRequest:request];
[self.view addSubview:webView];
mutableData = [NSMutableData data];
}
// 相關代理方法
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
if ([request.URL.scheme isEqualToString:@"https"]) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
connenction = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connenction start];
#pragma clang diagnostic pop
return NO;
}
return YES;
}
- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
// 判斷是否是信任服務器證書
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
// 創建一個憑據對象
NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
//告訴服務器客戶端信任證書
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
} else {
if ([challenge previousFailureCount] == 0) {
[[challenge sender] continueWithoutCredentialForAuthenticationChallenge:challenge];
} else {
[[challenge sender] continueWithoutCredentialForAuthenticationChallenge:challenge];
}
}
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
NSLog(@"response %@",response);
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[mutableData appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *html = [[NSString alloc] initWithData:[mutableData copy] encoding:NSUTF8StringEncoding];
[webView loadHTMLString:html baseURL:[[NSURL alloc] init]];
[connenction cancel];
[mutableData setData:[NSData data]];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
//清空數據
[mutableData setData:[NSData data]];
}
以上方法親測可行，而且如果你在用http請求時通過 bridgeWebview 實現了JS交互，也是可以的，不會有任何影響，只需在你之前的 UIWebviewController 中實現上面的幾個代理方法 就可以了，這樣既兼容了 http 請求 也可以兼容 https 請求。本人也只是稍微研究了下，具體有什么不足的地方還請大神們指點出來。。
