oc block链式编程

利用block实现链式编程

@interface Person : NSObject- (Person *(^)(NSString *name))study;- (Person *(^)())run;@end

#import "Person.h"@implementation Person- (Person *(^)(NSString *))study{    return ^(NSString *name){        NSLog(@"study----%@", name);        return self;    };}- (Person *(^)())run{    return ^{        NSLog(@"run----");        return self;    };}@end

int main(int argc, const char * argv[]){    @autoreleasepool {        Person *p = [[Person alloc] init];        p.study(@"xx宝典").run().study(@"xx剪发");    }    return 0;}
