CHGIntent

介绍

CHGIntent将所有类视为组件，组件与组件之间的通信包括传递参数、请求码，结果处理等。组件之间实现完全解耦合。ViewController基于这种思想进行封装。特别适合多模块间的调用。

封装了打开ViewController时传递参数以及返回ViewController中需要返回值的功能。

打开一个ViewController并接收ViewController的返回值

__weak typeof(self) weakSelf = self;
    CHGIntent * intent = [[CHGIntent alloc] initWithRequester:self
                                   target:@"Sample2ViewController"
                                   params:@"发送参数"
                              requestCode:1
                     onReceiveResultBlock:^id(id data, NSInteger requestCode, CHGIntentResultCode intentResultCode) {
                         __strong typeof(weakSelf) strongSelf = weakSelf;
                         [strongSelf.btn setTitle:data forState:UIControlStateNormal];
                         return nil;
                     }] ;
    [intent pushViewControllerAnimated:YES];

将数据返回给客户组件

[self setResultWithData:@"测试返回数据" resultCode:CHGIntentResultCodeSuccess];

打开URL

[[CHGIntent initWithRequester:self
                           target:@"http://taobao.com"
                           params:nil
                      requestCode:1
             onReceiveResultBlock:^id(id data, NSInteger requestCode, CHGIntentResultCode resultCode) {
                 
                 return nil;
             }] openAsUrl];

model向model发送请求

#import "Person.h"
#import "CHGIntent.h"

@implementation Person

/**
 对狗狗说话
 
 @param words 说话内容
 */
-(void)say2Dog:(NSString*)words {
    [[[CHGIntent alloc] initWithRequester:self
                                   target:@"Dog"
                                   params:words
                              requestCode:1
                     onReceiveResultBlock:^id(id data, NSInteger requestCode, CHGIntentResultCode resultCode) {
                         NSLog(@"data:%@",data);
                         return nil;
                     }] sendRequest];
}

@end

#import "Dog.h"

@implementation Dog


- (instancetype)init
{
    self = [super init];
    if (self) {
        //模拟返回数据给调用组件   3秒后返回结果
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [self waggedHisTail];
        });
    }
    return self;
}

-(void)waggedHisTail {
    [self setResultWithData:@"我来了" resultCode:CHGIntentResultCodeSuccess];
    [self close];//如果不再需要向组件回消息 需要关闭
}
