+ (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; }
