OC链式编程

Masonry等第三方库采用链式调用方式，使用时够简单、惊艳。下面来模仿一下，分析就省略了，so直接看代码。

1.Person.h

#import <Foundation/Foundation.h>

@interface Person : NSObject

- (Person *(^)(NSString *))name;
- (Person *(^)(NSString *))address;

@end

2.Person.m

#import "Person.h"

@interface Person ()
{
    NSString *_name;
    NSString *_address;
}

@end

@implementation Person

- (Person *(^)(NSString *))name {
    return ^Person *(NSString *name){
        NSLog(@"%@--%@", NSStringFromSelector(_cmd), name);
        _name = name;
        return self;
    };
}

- (Person *(^)(NSString *))address {
    return ^Person *(NSString *address){
        NSLog(@"%@--%@", NSStringFromSelector(_cmd), address);
        _address = address;
        return self;
    };
}

- (NSString *)description {
    return [NSString stringWithFormat:@"{name:%@,address:%@}", _name, _address];
}
@end

3.main.m

#import <Foundation/Foundation.h>
#import "Person.h"

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        Person *person = [Person new];
        person.name(@"Jack").address(@"USA");
        NSLog(@"person = %@", person);
    }
    return 0;
}
