在ViewController载入的时候，生成并添加Invocation

[self  addInvocation:WebServcieAddressTextselector:@selector(invokeTest)];

 

-(void)addInvocation:(NSString*)title selector:(SEL)selector{

    

    NSMethodSignature *methodSignature = [[selfclass] instanceMethodSignatureForSelector:selector];//获得类和方法的签名

    NSInvocation *invocation = [NSInvocationinvocationWithMethodSignature:methodSignature];

    //从签名获得调用对象

    [invocation setTarget:self];

    invocation.target=self;

    invocation.selector=selector;

    

    [invocationArrayaddObject:invocation];

    [titleArrayaddObject:title];

}

-(void)invokeTest{

    NSLog(@"Test invoked");

}

 

点击UITableView中的某一行的时候，根据IndexPath读取出NSInvocation，并且执行。

 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

{

    NSInvocation*invc=[invocationArrayobjectAtIndex:indexPath.row];

    [invc invoke];

}
