ObjObject *ob1 = [[ObjObject alloc] init];

[ob2 prientObject:@"S2"];

#pragm  mark    ObjObject

@implementation ObjObject

{

NSLog(@"%@",self);

[self logObject];

}

-(void)logObject

{

k++;

NSLog(@"ppp %d",k);

}

@end

#pragm mark   log

self 分别代表  

self  == ob1
self == ob2      表示对象     - 号方法

相信好多人 都认为  self 就是简简单单说当前类的解释。。。。。。个人感觉有错误，不完美哎哎。。。
