1-3编程思想---函数是编程

RAC编程思想---函数是编程

//  函数式编程思想:是将操作尽可能写在一起!嵌套的函数!!
//  本质:就是往方法里面传入Block,方法中嵌套Block调用.

#import "ViewController.h"
#import "sumManager.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    sumManager * mgr = [[sumManager alloc]init];
    int result = [[mgr manager:^int(int result) {
        //放计算代码
        result += 10;
        result *= 2;
        return result;
    }] result];
    NSLog(@"%d",result);
    
    
}

#import <Foundation/Foundation.h>

@interface sumManager : NSObject

/**  */
@property(assign,nonatomic)int result;

//计算
-(instancetype)manager:(int(^)(int result))sumBlock;

@end

#import "sumManager.h"

@implementation sumManager
-(instancetype)manager:(int (^)(int result))sumBlock
{
    _result = sumBlock(_result);
    return self;
