处理这个问题的初衷是：后端返回的用于跳转web页面的URL含有中文，WKWebView在加载包含中文的URL时发生了转义而无法加载只是显示空白页面。需要对包含中文的URL进行编码处理以防止发生转义。

处理方式很简单：

- (NSString*)urlEncode:(NSString*)urlString {

#pragma clang diagnostic push

#pragma clang diagnostic ignored"-Wdeprecated-declarations"

NSString *encodedString = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,

(CFStringRef)urlString,

(CFStringRef)@"!$&'()*+,-./:;=?@_~%#[]",

NULL,

kCFStringEncodingUTF8));

returnencodedString;

#pragma clang diagnostic pop

}

- (NSString*)urlDecode:(NSString*)urlString {

#pragma clang diagnostic push

#pragma clang diagnostic ignored"-Wdeprecated-declarations"

CFStringEncoding en = CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding);

NSString *decoded = [urlString stringByReplacingOccurrencesOfString:@"+"

withString:@" "];

decoded = (__bridge_transferNSString*)

CFURLCreateStringByReplacingPercentEscapesUsingEncoding(

NULL,

(__bridgeCFStringRef)decoded,

CFSTR(""),

en);

returndecoded;

#pragma clang diagnostic pop

}

对需要编码处理的URL进行编码处理即可，例子如下：

NSString *urlStr = @"https://pay-zto-test.zt-express.com/cashier-static/h5/cashier?systemCode=10007&sceneCode=10025&sign=ed37f0a3a541af5aa11cd273c65f2e44&partnerOrderCode=Z1007876566test&payTypeCode=TC0036&payMethodCode=10002&recipientName=中通快递&platform=txkdg";

NSString*encodeString = [self urlEncode:urlStr];

NSLog(@"编码encodeString===%@",encodeString);

打印结果为： https://pay-zto-test.zt-express.com/cashier-static/h5/cashier?systemCode=10007&sceneCode=10025&sign=ed37f0a3a541af5aa11cd273c65f2e44&partnerOrderCode=Z1007876566test&payTypeCode=TC0036&payMethodCode=10002&recipientName=%E4%B8%AD%E9%80%9A%E5%BF%AB%E9%80%92&platform=txkdg

需要解码回中文的话字节调用解码方法即可。
