iOS 循环创建按钮（单行和多行）

创建单行的按钮

CGFloatStart_X    =    15.0f;    // 第一个按钮的X坐标

    CGFloatStart_Y        =  _password.frame.origin.y+_password.frame.size.height+35;    // 第一个按钮的Y坐标

    CGFloatWidth_Space    =  15.0f;    // 2个按钮之间的横间距

    CGFloatButton_Height  =35.0f  ;  // 高

    CGFloatButton_Width  = (loginView.frame.size.width-45)/2;  // 宽

    NSArray* titleArray =@[@"取消",@"登录"];

    for(inti =0; i <2; i++) {

        // 圆角按钮

        UIButton* Button = [[UIButtonalloc]init];

        Button.tag= i;//这句话不写等于废了

        Button.frame=CGRectMake(i * (Button_Width + Width_Space) + Start_X,  Start_Y, Button_Width, Button_Height);

        Button.layer.masksToBounds=YES;

        Button.layer.cornerRadius=5;

        [ButtonsetTitle:titleArray[i]forState:UIControlStateNormal];

        if(i==0) {

            Button.backgroundColor= [UIColorcolorWithRed:148.0/255.0green:148.0/255.0blue:148.0/255.0alpha:1];

        }else{

         Button.backgroundColor= [UIColorcolorWithRed:79.0/255.0green:139.0/255.0blue:244.0/255.0alpha:1];

        }

        [ButtonaddTarget:selfaction:@selector(ButtonAction:)forControlEvents:UIControlEventTouchUpInside];

        [loginViewaddSubview:Button];

    }

多行多列的按钮

CGFloatStart_X  =15.0f;    // 第一个按钮的X坐标

    CGFloatStart_Y = whightView.Y+30;    // 第一个按钮的Y坐标

    CGFloatWidth_Space =15.0f;      // 2个按钮之间的横间距

    CGFloatHeight_Space=20.0f;    // 竖间距

    CGFloatButton_Height =40.0f;    // 高

    CGFloatButton_Width  =(SCREEN_WIDTH-45)/2;    // 宽

    NSArray* titleArray =@[@"失败",@"执行中",@"成功",@"中断"];

    _ButtonArray = [[NSMutableArray alloc]init];

    for(inti =0; i < titleArray.count

         ; i++) {

        NSIntegerindex = i %2;

        NSIntegerpage = i /2;

        // 圆角按钮

        UIButton*PlanTypeBtn = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];

        PlanTypeBtn.tag= i;//这句话不写等于废了

        PlanTypeBtn.frame=CGRectMake(index * (Button_Width + Width_Space) + Start_X, page  * (Button_Height + Height_Space)+Start_Y, Button_Width, Button_Height);

        [PlanTypeBtnsetTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

        [PlanTypeBtnsetTitle:titleArray[i]forState:UIControlStateNormal];

        PlanTypeBtn.layer.cornerRadius=5;

        PlanTypeBtn.layer.masksToBounds=YES;

        PlanTypeBtn.layer.borderWidth=1;

        PlanTypeBtn.layer.borderColor = RGBCOLOR(148,148,148).CGColor;

        [selfaddSubview:PlanTypeBtn];

        [_ButtonArray addObject:PlanTypeBtn];

        //按钮点击方法

        [PlanTypeBtnaddTarget:selfaction:@selector(PlanTypeBtnClick:)forControlEvents:UIControlEventTouchUpInside];

    }

    // 多个按钮的展示

    -(void)PlanTypeBtnClick:(UIButton*)btn{

        for(UIButton *btn1in_ButtonArray){

            if(btn1.tag == btn.tag){

                [btn1 setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

                btn1.layer.borderColor = RGBCOLOR(79,139,244).CGColor;

                btn1.backgroundColor =RGBCOLOR(79,139,244);

            }else{

                btn1.layer.borderWidth =1;

                btn1.layer.borderColor = RGBCOLOR(148,148,148).CGColor;

                btn1.backgroundColor =[UIColor clearColor];

            }

        }
