Development mode for iOS agent (delegate)

1. Proxy mode in IOS development use a lot of such as Uitableview,uicollectioin Proxy way, with too much, the surface of the consciousness is, entrust others to do things, help Viewcontroller to solve a series of problems, directly on the code:

In ChilderViewController.h:

#import <UIKit/UIKit.h>

@protocol childerviewcontrollerdlegate <nsobject>

 - (void) GetColor: (uicolor *) color;

@end

@interface childerviewcontroller: uiviewcontroller

@property (nonatomic,weak)ID <childerviewcontrollerdlegate >delegate;

@end

In CHILDERVIEWCONTROLLER.M:

#import "ChilderViewController.h"

@interface childerviewcontroller ()

@end

@implementation Childerviewcontroller

-(void) viewdidload {

[Super viewdidload];

self. View. BackgroundColor = [uicolor whitecolor];

UIButton *button = [[UIButton alloc] initwithframe:cgrectmake(0, 100, 200, 50 )];

[Button addTarget:self action:@selector(show) forcontrolevents: UIControlEventTouchUpInside];

//Button.backgroundcolor = [Uicolor redcolor];

[Button settitlecolor: [uicolor blackcolor] forstate:uicontrolstatenormal ];

[Button settitle:@ " return to the calling agent " forstate:uicontrolstatenormal];

[self. View addsubview: button];

}

-(void) show {

[self. Delegate getColor: [uicolor redcolor]];

[self. Navigationcontroller poptorootviewcontrolleranimated:YES];

}

-(void) didreceivememorywarning {

[Super didreceivememorywarning];

//Dispose of any resources the can be recreated

}

In a mainvccongtroller push past Childerviewcontrller, click the button in Childerviewcontroller to change the background color of the root view:

Mainviewcontroller.m

#import "MainViewController.h"

#import "ChilderViewController.h"

@interface Mainviewcontroller () <childerviewcontrollerdlegate>

@end

@implementation Mainviewcontroller

-(void) viewdidload {

[Super viewdidload];

additional setup after loading the view from its nib.

}

-(void) didreceivememorywarning {

[Super didreceivememorywarning];

//Dispose of any resources, can be recreated.

}

-(void) GetColor: (uicolor *) color{

self. View. BackgroundColor = color;

NSLog(@ "Change color ...");

}

-(ibaction) OnClick: (ID) Sender {

childerviewcontroller *childervc = [[childerviewcontroller alloc]init];

CHILDERVC. delegate = self;

[self. Navigationcontroller pushviewcontroller: childervc animated:YES];

}
