Obj-C的hello,world 2

https://github.com/facebook/facebook-ios-sdk/blob/master/src/FBAppEvents.h

+ (void)logEvent:(NSString *)eventName
      valueToSum:(double)valueToSum
      parameters:(NSDictionary *)parameters;

昨天晚上，我去看了下facebook，google的obj-c项目，看下他们是怎么处理多参数方法的，发现他们还是把方法名写成了多个部分，我在想这么做是不是其实还是有些道理的，于是改了下自己的DEMO，看起来顺眼多了

#import <Foundation/Foundation.h>

@interface Employee : NSObject
{
    NSString *firstName;
    NSString *lastName;
}
@end

@implementation Employee

//  这里的方法名是 setFirstName:andLastName:
-(void)setFirstName :(NSString *)firstName andLastName:(NSString *)lastName
{
    self->firstName = firstName;
    self->lastName = lastName;
}

-(void)say
{
    NSLog(@"HELLO i'm %@ %@",lastName, firstName);
}

@end

int main(int argc, const char * argv[])
{

    @autoreleasepool {
        id employee = [Employee new];
        [employee setFirstName:@"li" andLastName:@"shujun"];
        [employee say];
        
    }
    return 0;
}
