Initial experience of CTMediator

Premise of contact

The requirements for iOS development are gradually evolving with the development of The Times. I have seen a lot of JD requirements these days, and there is more or less a name – componentization.

Personal understanding of componentization

At the beginning, MY understanding of componentization was still very vague, and I always felt that it was high-end, grand and classy. It’s like you can’t even touch it. My understanding is to make several small functional components in the project private library, so that he does not depend on the project, reduce the coupling in the project. It’s actually used in general development. CocoaPods I understand is also a form of componentization.

CTMediator – broker

Personal understanding for the jump of the unified delivery center, a bit and logistics transfer station about the same. Unified handling of page jump logic.

How to use CTMediator

General jump to native page

#import "CTMediatorTestViewController.h" #import "CTMediatorPushViewController.h" @interface CTMediatorTestViewController () @property (nonatomic, strong) UIButton *normalPushButton; @end @implementation CTMediatorTestViewController - (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:self.normalPushButton]; [self.normalPushButton mas_makeConstraints:^(MASConstraintMaker *make) { make.top.equalTo(self.view).offset(100);  make.left.equalTo(self.view).offset(10); }]; } # pragma mark - click event - (void) normalPushButtonTapAction: (UIButton *) button {CTMediatorPushViewController * normalPushVC =  [[CTMediatorPushViewController alloc]init]; [self.navigationController pushViewController:normalPushVC animated:YES]; } #pragma mark - (UIButton *)normalPushButton{if (! _normalPushButton) { _normalPushButton = [UIButton buttonWithType:UIButtonTypeCustom]; [_normalPushButton setTitle: @ "conventional Push" forState: UIControlStateNormal]; [_normalPushButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [_normalPushButton addTarget:self action:@selector(normalPushButtonTapAction:) forControlEvents:UIControlEventTouchUpInside]; } return _normalPushButton; } @endCopy the code

This is a very simple jump to a native page. #import “xxxxXXx. h” when we want to jump from one page to another ViewController. Over time the page will have many import files. If the ViewController can be used in other projects, why not include the #import “xxxxXXx. h” as well? This makes the project highly coupled.

CTMediator target-action redirects the page

We’ll still use the two controllers above.

1. Create a Target – the Action

We need to create a Target_Push class, and in the.h file we need to add a function to instantiate the target controller, as well as some assignment if we need parameters.

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN

@interface Target_Push : NSObject

- (UIViewController *)Action_NativeToCTMediatorPushViewController:(NSDictionary *)params;

@end
Copy the code

Then we implement the function we defined in the.m file

#import "Target_Push.h"
#import "CTMediatorPushViewController.h"


@implementation Target_Push

- (UIViewController *)Action_NativeToCTMediatorPushViewController:(NSDictionary *)params{
    CTMediatorPushViewController *pushVC = [[CTMediatorPushViewController alloc]init];
    if ([params valueForKey:@""]) {
        
    }
    return pushVC;
}

@end
Copy the code

2. Create CTMediator Category

We define such a function in the created classification

#import <CTMediator/CTMediator.h>
#import "BaseViewController.h"

@interface CTMediator (PushActions)

- (BaseViewController *)dtp_mediator_ctmediatorPushViewControllerWithParams:(NSDictionary *)params;

@end
Copy the code

Here the ViewController uses BaseViewController and don’t forget if you use UIViewController \#import

. And then we implement this function

#import "CTMediator+PushActions. H "// 1. kCTMediatorTarget_Push the string is NSString * const in the XXX part of target_xxx. h kCTMediatorTarget_Push = @"Push"; / / 2. KCTMediatorActionNativeTo_NewsViewController is Target_xxx. H Action_xxxx function name defined in part of XXX nsstrings * const kCTMediatorActionNativeTo_NewsViewController = @"NativeToCTMediatorPushViewController"; @implementation CTMediator (PushActions) - (BaseViewController *)dtp_mediator_ctmediatorPushViewControllerWithParams:(NSDictionary *)params{ BaseViewController *viewController = [self  performTarget:kCTMediatorTarget_Push action:kCTMediatorActionNativeTo_NewsViewController params:params shouldCacheTarget:NO]; If ([viewController isKindOfClass:[BaseViewController Class]]) {GGLog(@"%@ successfully instantiated page ", NSStringFromSelector(_cmd)); return viewController; }else{GGLog(@"%@ failed to instantiate the page ", NSStringFromSelector(_cmd)); return [[BaseViewController alloc]init]; } } @endCopy the code

Call the implementation

#import "CTMediatorTestViewController.h" #import "CTMediator+PushActions.h" @interface CTMediatorTestViewController () @property (nonatomic, strong) UIButton *normalPushButton; @end @implementation CTMediatorTestViewController - (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:self.normalPushButton]; [self.normalPushButton mas_makeConstraints:^(MASConstraintMaker *make) { make.top.equalTo(self.view).offset(100);  make.left.equalTo(self.view).offset(10); }]; } # pragma mark - click event - (void) normalPushButtonTapAction: (UIButton *) button {NSDictionary * params = @{@"title":@"CTMediatorPushViewController"}; BaseViewController *pushVC = [[CTMediator sharedInstance] dtp_mediator_ctmediatorPushViewControllerWithParams:params]; [self.navigationController pushViewController:pushVC animated:YES]; } #pragma mark - (UIButton *)normalPushButton{if (! _normalPushButton) { _normalPushButton = [UIButton buttonWithType:UIButtonTypeCustom]; [_normalPushButton setTitle: @ "Target - the Action to achieve page jump" forState: UIControlStateNormal]; [_normalPushButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [_normalPushButton addTarget:self action:@selector(normalPushButtonTapAction:) forControlEvents:UIControlEventTouchUpInside]; } return _normalPushButton; } @endCopy the code

But the process doesn’t feel as simple as the previous direct Push. Maybe my current understanding is not deep enough ~~~
