我要评论
这是PSDJsBridge里的一个方法
下面是伪代码
void -[PSDJsBridge _flushMessageQueue](void * self, void * _cmd) {
r15 = self;
if ([self isBridgeReady] == 0x0) {
[r15 setIsBridgeReady:0x1];
}
objc_initWeak(&var_30, r15);
rbx = [_PSDConfigurationGet() retain];
r14 = [rbx shouldCallJSAPIWithToken];
[rbx release];
if (r14 != 0x0) {
var_38 = [[r15 contentView] retain];
r13 = [_PSGetTokenWithContentView() retain];
rbx = 0x1;
}
else {
r13 = @"";
rbx = 0x0;
}
r12 = [[NSString stringWithFormat:@"AlipayJSBridge._fetchQueue('%@');", r13] retain];
if (rbx != 0x0) {
[r13 release];
[var_38 release];
}
rax = objc_loadWeakRetained(&r15->_contentView);
*(&var_48 + 0xffffffffffffffe0) = __NSConcreteStackBlock;

*(int8_t *)(&var_48 + 0x8) = r14;
objc_copyWeak(&var_48, &var_30);
[rax evaluateJavaScript:r12 completionHandler:&var_68];
[rax release];
objc_destroyWeak(&var_48);
[r12 release];
objc_destroyWeak(&var_30);
return;

}
r14 = [rdi retain];
[rbx release];
var_48 = r14;

}

[rbx release];
rax = [r15 release];
return rax;
}
然后对这个代码还原一下可以运行的代码（不保证完全正确）
需要引入PSDUtils.h头文件
-(void)_flushMessageQueueS{
if ([self isBridgeReady] == 0x0) {
[self setIsBridgeReady:0x1];
}
BOOL r14 = [[PSDConfiguration defaultConfiguration] shouldCallJSAPIWithToken];
BOOL rbx;
NSString *r13;
if (r14 != 0x0) {
r13 = PSGetTokenWithContentView([self contentView]);
rbx = 1;
}else{
r13 = @"";
rbx = 0x0;
}
NSString *r12 = [NSString stringWithFormat:@"AlipayJSBridge._fetchQueue('%@');", r13];
[self.contentView evaluateJavaScript:r12 completionHandler:^(NSString* str, NSError * _Nullable error) {
NSString * rbx = [str description];
NSString* rdi = @"";
if (rbx != 0x0) {
rdi = rbx;
}
if ([self.contentView isKindOfClass:[WKWebView class]]) {
NSURL* r12 = [[self contentView] URL];
NSString* rbx3 = [r12 absoluteString];
[self _doFlushMessageQueue:rbx url:rbx3];
}else{
WKWebView* rax = [self contentView];
[rax evaluateJavaScript:@"document.location.href" completionHandler:^(NSString* strr, NSError * _Nullable error) {
NSString* rbx2 = [strr description];
[self _doFlushMessageQueue:rbx url:rbx2];
}];
}
}];
// [self _flushMessageQueueS];
}
本想这里可以看看白屏问题，可是只是原生调用了h5,执行了一下交互代码,这个思路也暂停一下。
