WKWebView cookie同步問題：
利用runtime ?在loadRequest時(shí)，先同步一下cookie就可以了！
以下是代碼：
.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];
}
