处理WKContentView双击crash

解决WKContentView没有isSecureTextEntry方法造成的crash

在程序启动，或者webview打开之前调用下以下方法

/**
 处理WKContentView的crash
 [WKContentView isSecureTextEntry]: unrecognized selector sent to instance 0x101bd5000
 */
+ (void)progressWKContentViewCrash {
    //由于客户端只支持8.0以上版本，所以不用判断系统版本
    static dispatch_once_t onceToken;
    
    dispatch_once(&onceToken, ^{
        const char *className = @"WKContentView".UTF8String;
        Class WKContentViewClass = objc_getClass(className);
        SEL isSecureTextEntry = NSSelectorFromString(@"isSecureTextEntry");
        SEL secureTextEntry = NSSelectorFromString(@"secureTextEntry");
        BOOL addIsSecureTextEntry = class_addMethod(WKContentViewClass, isSecureTextEntry, (IMP)isSecureTextEntryIMP, "B@:");
        BOOL addSecureTextEntry = class_addMethod(WKContentViewClass, secureTextEntry, (IMP)secureTextEntryIMP, "B@:");
        if (!addIsSecureTextEntry || !addSecureTextEntry) {
            LOGINFO(@"WKContentView-Crash->修复失败");
        }
    });
}


/**
 实现WKContentView对象isSecureTextEntry方法
 @return NO
 */
BOOL isSecureTextEntryIMP(id sender, SEL cmd) {
    return NO;
}


/**
 实现WKContentView对象secureTextEntry方法
 @return NO
 */
BOOL secureTextEntryIMP(id sender, SEL cmd) {
    return NO;
}
