//修改ua

NSString* userAgent = [self.myWebView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];

NSString *executableFile = [[[NSBundlemainBundle]infoDictionary]objectForKey:(NSString *)kCFBundleExecutableKey];

NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];

//系统ua

NSString* hereUa = [NSString stringWithFormat:@"%@ %@/%@",

userAgent,

executableFile,version];

//加载PDF的ua

NSString * webUa = @"Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-us) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16";

[[NSUserDefaults standardUserDefaults] registerDefaults:@{@"UserAgent" : webUa, @"User-Agent" : hereUa}];

//===============================================================================================

NSURLRequest* request = [NSURLRequest requestWithURL:courceUrl];

NSString *lowerCaseString1 = [courseType lowercaseString];//转成小写

// 修改webView的request的ua

if ([lowerCaseString1 isEqualToString:@"pdf"]) {

[request valueForHTTPHeaderField:@"User-Agent"];

}else{

[request valueForHTTPHeaderField:@"UserAgent"];

}

[self.myWebView loadRequest:request];
