话不多说，我赶时间，所以直接来一份代码吧。如果有不懂或者不清楚的欢迎大家留言，我会在看到后的第一时间回复你哦。
- 获取UA；
// 页面加载完成之后调用
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{
NSLog(@"didFinishNavigation");
self.launchScreenShowStart = [[NSDate date]timeIntervalSince1970];
[webView evaluateJavaScript:@"navigator.userAgent" completionHandler:^(id result, NSError *error) {
NSLog(@"userAgent :%@", result);
}];
}
打印结果为：
userAgent :Mozilla/5.0 (iPhone; CPU iPhone OS 10_0_1 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) Mobile/14A403
- 自定义UA：
- (void)viewDidLoad {
[super viewDidLoad];
if (self.isYueTTAssistent) {
if (@available(iOS 12.0, *)){
//由于iOS12的UA改为异步，所以不管在js还是客户端第一次加载都获取不到，所以此时需要先设置好再去获取（1、如下设置；2、先在AppDelegate中设置到本地）
NSString *baseAgent = @"Mozilla/5.0 (iPhone; CPU iPhone OS 11_4 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15F79";
NSString *userAgent = [NSString stringWithFormat:@"%@%@",baseAgent,CustomUserAgent];
[self.kWKWebView setCustomUserAgent:userAgent];
}
//需要自定义UA
@weakify(self);
[self.kWKWebView evaluateJavaScript:@"navigator.userAgent" completionHandler:^(id result, NSError *error) {
@strongify(self);
NSString *userAgent = result;
NSString *newUserAgent;
if (![result containsString:CustomUserAgent]) {
newUserAgent = [userAgent stringByAppendingString:CustomUserAgent];
}else{
newUserAgent = result;
}
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:newUserAgent, @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];
[[NSUserDefaults standardUserDefaults] synchronize];
if (@available(iOS 9.0, *)) {
[self.kWKWebView setCustomUserAgent:newUserAgent];
} else {
// Fallback on earlier versions
[self.kWKWebView setValue:newUserAgent forKey:@"applicationNameForUserAgent"];
}
//加载请求必须同步在设置UA的后面
NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:self.url];
[self.kWKWebView loadRequest:request];
}];
}else{
NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:self.url];
[self.kWKWebView loadRequest:request];
}
}
再次打印结果为：
userAgent :Mozilla/5.0 (iPhone; CPU iPhone OS 10_0_1 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) Mobile/14A403;app/customeruseragent
