参考这篇官方文章:Native Modules
用一个RCTRootView作为iOS里一个Controller的view。在RN层的左上角返回按钮点击后pop回iOS层。发现无法执行,调试发现controller的navigationCont的值是空的。发现与RN交互的这个self地址和iOS层的self并不是同一个内存地址,RN应该是deep copy了iOS层的self等,导致无法进行pop。
有一种解决方案:写一个单例TCReactNativeBridge,专门给用来处理原生和React Native之间的交互,TCReactNativeBridge暴露一个delegate给需要交互的原生Controller,用来接收React Native传递过来的事件和参数,并用回调的方式传回参数给React Native。
#import "RCTBridgeModule.h"
@protocol TCReactNativeBridgeDelegate <NSObject>
@optional
-(void)rn_leftBarButtonClicked;
-(void)rn_rightBarButtonClicked;
-(void)rn_reciveFromReactNative:(NSString*)action
paramas:(NSArray*)paramas
callback:(RCTResponseSenderBlock)callback;
@end
@interface TCReactNativeBridge : NSObject<RCTBridgeModule>
@property (nonatomic,weak) id<TCReactNativeBridgeDelegate> delegate;
+(instancetype)sharedIncetance;
@end
@implementation TCReactNativeBridge
RCT_EXPORT_MODULE()
+(instancetype)sharedIncetance
{
static TCReactNativeBridge *incetance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^
{
incetance = [[TCReactNativeBridge alloc] init];
});
return incetance;
}
<span style="font-family: Arial, Helvetica, sans-serif;">
</span>
<span style="font-family: Arial, Helvetica, sans-serif;">-(void)rn_reciveFromReactNative:(NSString*)action</span>
paramas:(NSArray*)paramas
callback:(RCTResponseSenderBlock)callback
{
if ([action isEqualToString:@"hideTabbar"]) {
[[TCGlobal sharedIncetance].tabBarController setTabBarHidden:YES animated:YES];
}
else if ([action isEqualToString:@"showTabbar"]) {
[[TCGlobal sharedIncetance].tabBarController setTabBarHidden:NO animated:YES];
}
else if ([action isEqualToString:@"motherForumBoardCreateNewPost"]) {
TMCreateMotherForumPostViewController *c = [[TMCreateMotherForumPostViewController alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:c];
[self presentViewController:nav animated:YES completion:nil];
}
}
在需要和React Native交互的地方接收delegate
-(void)rn_reciveFromReactNative:(NSString*)action
paramas:(NSArray*)paramas
callback:(RCTResponseSenderBlock)callback
{
if ([action isEqualToString:@"hideTabbar"]) {
[[TCGlobal sharedIncetance].tabBarController setTabBarHidden:YES animated:YES];
}
else if ([action isEqualToString:@"showTabbar"]) {
[[TCGlobal sharedIncetance].tabBarController setTabBarHidden:NO animated:YES];
}
}
