    NSUInteger startOfLine = [head length];

    NSString* tail = [head substringFromIndex:startOfLine];
    CGSize lineSize = [tail sizeWithFont:note.font forWidth:note.contentSize.width lineBreakMode:UILineBreakModeWordWrap];
    CGPoint cursor = origin;
    cursor.x += lineSize.width+15;
    cursor.y += initialSize.height - lineSize.height-130;

使用button.tag属性区分您的所有按钮。

并可以根据tagValue

执行任务

if(button.tag==0)
{
//do somthing
}
else
{
//do other thing
}
