//综合多个条件
_validSignal = [[RACSignal combineLatest:@[<#validSignal_1#>, <#validSignal_2#>,<#validSignal_3#>, <#validSignal_4#>, <#validSignal_5#>, <#validSignal_6#>]] map:^id(RACTuple *tuple) {

}];
RAC(nextButton, enabled) = _validSignal;

4.单个数据回传
在ViewController_1中
- (void)handleButtonClick:(UIButton *)sender

self.model.LivechannelId = channel.Id;
self.model.CarbrandId = channel.CarbrandtId;
}];
[self.navigationController pushViewController:vc_2 animated:YES];
}
在ViewController_2中
ViewController_2.h
@property (nonatomic, strong) RACSubject *<#doneSelectingSubjectt#>;
ViewController_2.m
- (RACSubject *)<#doneSelectingSubjectt#>
{
if (!_<#doneSelectingSubjectt#>) {

}
return _<#doneSelectingSubject#>;
}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
for (<#Model#> *model in self.<#modeArray#>) {
model.selected = NO;
}
<#Model#> *<#modelName#> = self.<#modeArray#>[indexPath.item];
<#modelName#>.selected = YES;
[collectionView reloadData];
if (<#modelName#>.<#property is true#>) {
[self next:<#modelName#>];
}else {
if (<#有二级页面筛选条件#>) {
if (<#modelName#>.<#(属性)进入二级页面条件为真#>) { // 非保险
<#ViewController_3#> *vc_3 = [[<#ViewController_3#> alloc] init];
[vc_3.doneSelectingSubject subscribeNext:^(NSString *<#ReturnString#>) {
<#modelName#>.<#property#> = <#ReturnString#>;
[self done:<#modelName#>];
}];
[self.navigationController pushViewController:<#vc_3#> animated:NO];
}else {
[self done:<#modelName#>];
}
}else {
[self done:<#modelName#>];
}
}
}
#pragma mark 下一步
- (void)next:(<#Mode#> *)<#model#>
{
<#ViewController_#> *<#vc_#> = [[<#ViewController_#> alloc] init];
<#vc_#>.<#propertyName#> = <#mode#>.<#propertyName#>;
<#vc_#>.doneSelectingSubject = self.doneSelectingSubject;
[self.navigationController pushViewController:<#vc_#> animated:NO];
}
#pragma mark 完成
- (void)done:(<#Model#> *)<#model#>
{
////////如有需要实现多选
if (![<#model#>.<#propertyName#> isNotBlank]) {
<#mode#>.<#OtherPropertyName#> = <#@""#>;
}
[self.doneSelectingSubject sendNext:<#mode#>];
//如有需要退出
//1.退出到制定ViewController
UIViewController *vcTo = nil;
for (NSInteger i = 0; i < self.navigationController.viewControllers.count; i++) {

if ([vc isKindOfClass:NSClassFromString(@"<#ViewController#>")]) {
vcTo = vc;
break;
}
}
[self.navigationController popToViewController:vcTo animated:YES];
//2.直接popView
}
在ViewController_3中
ViewController_3.h
@property (nonatomic, strong) RACSubject *<#doneSelectingSubjectt#>;
ViewController_3.m
- (RACSubject *)<#doneSelectingSubjectt#>
{
if (!_<#doneSelectingSubjectt#>) {
_<#doneSelectingSubjectt#> = [RACSubject subject];
}
return _<#doneSelectingSubject#>;
}
#pragma mark 完成
- (void)done:(<#Model#> *)<#model#>
{
if (![<#model#>.<#propertyName#> isNotBlank]) {
<#mode#>.<#OtherPropertyName#> = <#@""#>;
}
[self.doneSelectingSubject sendNext:<#mode#>];
//如有需要可以退出
}
