iPhone编程中的@selector关键字 [英] @selector key word in iPhone programming

问题描述

-(void)displayNameBy:(NSString *)name {

-(void)displayNameBy:(NSString*)name{

    mylable.text = name;

}

我想使用@selector关键字调用此方法.

i want call this method using @selector keywords.

例如:

[MyButton addTarget:self action:***@selector(displayNameBy:name)*** forControlEvents:UIControlEventTouchUpInside];

这是我的粗体斜体.我可以从这里传递名称参数吗?当我尝试传递名称值时，出现错误.

Here bold italics is my doubt.. could i pass name parameter from here. when i try to pass name value i getting error.

在displayNameBy:name方法中获取名称值的任何方法.使用@selector关键字.

any way to get name value in the displayNameBy:name method . using @selector key words.

这里MyButton是我通过编程方式创建的.不在界面生成器中.

here MyButton i created by programatically . not in interface builder.

感谢和问候

推荐答案

具有中间方法.像:

{
   ...
   [MyButton addTarget:self action:@selector(displayName) forControlEvents:UIControlEventTouchUpInside];
   ...
}

-(void) displayName
{
   [self performSelector:@selector(displayNameBy:) withObject:@"name"];
}

-(void)displayNameBy:(NSString*)name{

    mylable.text = name;

}
