iOS WKWebView cookie同步问题

WKWebView cookie同步问题：

利用runtime  在loadRequest时，先同步一下cookie就可以了！

以下是代码：

.h

#import

NS_ASSUME_NONNULL_BEGIN

@interface WKWebView (SafeUrl)

+ (void)changeMethodOriginalSelector:(SEL)originalSelector swizzledSelector:(SEL)swizzledSelector;

- (NSURL *)xxx_URL;

- (nullable WKNavigation *)xxx_loadRequest:(NSURLRequest *)request;

@end

NS_ASSUME_NONNULL_END

.m

#import "WKWebView+SafeUrl.h"

@implementation WKWebView (SafeUrl)

+(void)load{

    NSString*className=NSStringFromClass(self.class);

    NSLog(@"classname%@",className);

    static dispatch_once_t onceToken;

    dispatch_once(&onceToken,^{

        SELoriginalSelector=@selector(URL);

        SELswizzledSelector=@selector(xxx_URL);

        [self changeMethodOriginalSelector:originalSelector swizzledSelector:swizzledSelector];

        SELoriginalSelector1=@selector(loadRequest:);

        SELswizzledSelector1=@selector(xxx_loadRequest:);

        [selfchangeMethodOriginalSelector:originalSelector1swizzledSelector:swizzledSelector1];

    });

}

+ (void)changeMethodOriginalSelector:(SEL)originalSelector swizzledSelector:(SEL)swizzledSelector{

    Classclass= [selfclass];

    MethodoriginalMethod=class_getInstanceMethod(class,originalSelector);

    MethodswizzledMethod=class_getInstanceMethod(class,swizzledSelector);

    BOOLdidAddMethod=

    class_addMethod(class,

                    originalSelector,

                    method_getImplementation(swizzledMethod),

                    method_getTypeEncoding(swizzledMethod));

    if(didAddMethod){

        class_replaceMethod(class,

                            swizzledSelector,

                            method_getImplementation(originalMethod),

                            method_getTypeEncoding(originalMethod));

    }else{

        method_exchangeImplementations(originalMethod,swizzledMethod);

    }

}

- (NSURL *)xxx_URL{

    NSThread *thread = [NSThread currentThread];

    if(thread.isMainThread) {

        return [self xxx_URL];

    }else{

        dispatch_semaphore_t signal = dispatch_semaphore_create(1);

        __blockNSURL*URL;

        dispatch_async(dispatch_get_main_queue(), ^{

            URL = [selfxxx_URL];

            dispatch_semaphore_signal(signal);

        });

        dispatch_semaphore_wait(signal, DISPATCH_TIME_FOREVER);

        returnURL;

    }

}

- (nullable WKNavigation *)xxx_loadRequest:(NSURLRequest *)request{

    NSMutableURLRequest *muRequest = nil;

    if ([request isKindOfClass:[NSMutableURLRequest class]]) {

        muRequest = (NSMutableURLRequest*)request;

    }else{

        muRequest = [requestmutableCopy];

    }

    NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];

    NSDictionary *dict = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];

    muRequest.allHTTPHeaderFields= dict;

    return [self xxx_loadRequest:muRequest];

}
