//主要知识点:

当创建多个Button时,而又每个Button触发的事件又是不同,那么可以通过

 SEL selector = NSSelectorFromString(methods[i]);//转换

例:

NSArray *titles =@[@"SAX解析",@"Dom解析第一种方式",@"Dom解析第二种方式",@"系统解析",@"字符串解析",@"数组解析",@"字典解析",@"Data解析"];

        NSArray *methods = @[@"handleSAX:",@"handleDomBtn1:",@"handleDomBtn2:",@"handleSystemJSON:",@"handleStrBtn:",@"handleArrBtn:",@"handleDicBtn:",@"handleDataBtn:"];

    CGFloat height = 70;

    for (int i = 0; i < 8; i++) {

       UIButton *SAXBtn = [UIButtonbuttonWithType:UIButtonTypeSystem];

        SAXBtn.frame =CGRectMake(60, height,200, 30);

        SAXBtn.backgroundColor = [UIColorgreenColor];

        [SAXBtnsetTitle:titles[i]forState:UIControlStateNormal];

        SEL selector =NSSelectorFromString(methods[i]);

        [SAXBtnaddTarget:selfaction:selectorforControlEvents:UIControlEventTouchUpInside];

        [self.viewaddSubview:SAXBtn];

        height +=40;

    }

For循环 button点击事件转换
