一、项目结构
二、主要代码
1、CoreManage.h
#import<Foundation/Foundation.h>@PRotocolSampleProtocol;//声明核心类的属性和方法@interfaceCoreManage : NSObject
@property(nonatomic,assign)id<SampleProtocol>delegate;- (void)doMainWork;@end//声明协议中的接口函数@protocolSampleProtocol <NSObject>@required- (void)innerTaskCallBack:(int) innerTaskSerialNo;
@optional- (void)resultDisplayCallBack:(NSString *)backInfo;@end
2、CoreManage.m
#import"CoreManage.h"@implementationCoreManage@synthesizedelegate=_delegate;- (id)init
{
self=[super init];if(self) {//初始化代码}returnself;
}- (void)doMainWork
{
NSLog(@"核心类完成工序0");
NSLog(@"核心类完成工序1");
[self.delegateinnerTaskCallBack:2];//工序2通过外部类回调函数完成NSLog(@"核心类完成工序3");
[self.delegateresultDisplayCallBack:@"成功"];//通过外部类回调函数显示任务完成结果}@end
3、OuterClass.h
#import<Foundation/Foundation.h>#import"CoreManage.h"@interfaceOuterClass : NSObject<SampleProtocol>
- (void)run;@end
4、OuterClass.m
#import"OuterClass.h"@implementationOuterClass- (void)run
{
CoreManage*coreManage=[[CoreManage alloc] init];
coreManage.delegate=self;
[coreManage doMainWork];
}//回调函数1- (void)innerTaskCallBack:(int) innerTaskSerialNo{
NSLog(@"外部类的回调函数，完成工序%d",innerTaskSerialNo);
}//回调函数2- (void)resultDisplayCallBack:(NSString *)backInfo{
NSLog(@"外部类的回调函数，输出完成结果：%@",backInfo);
}@end
5、AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window=[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
OuterClass*outerClass=[[OuterClass alloc]init];
[outerClass run];
self.window.backgroundColor=[UIColor whiteColor];
[self.window makeKeyAndVisible];returnYES;
}
