iphone开发实现单选框

//画图 

-(void)addSecondZone:(UIView*)contentView

//按钮图片

UIImage *selecticonNo =[UIImage imageNamed:SelecticonNo];

UIImage *selecticon =[UIImage imageNamed:Selecticon]; 

        UIView *childSecondView; 

        childSecondView = [[UIView alloc] initWithFrame:CGRectMake(0, 155 , 320, 500)];


       int pointY =0;

            for (int i=0;i<4;i++) {

[childSecondView addSubImageView:contentbar Rect:CGRectMake(0, pointY, 320,contentbar.size.height/2)];

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

[button setBackgroundImage:selecticonNo forState:UIControlStateNormal];

[button setBackgroundImage:selecticon forState:UIControlStateSelected];

button.frame=CGRectMake(310-selecticonNo.size.width/2, pointY+2,                               selecticonNo.size.width/2,selecticonNo.size.height/2);

[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

button.tag=i + 1;

[button addTarget:self action:@selector(selectTransType:) forControlEvents:UIControlEventTouchUpInside];

if(i==0)

{

[button setSelected:YES];

}

[childSecondView addSubview:button];

pointY += 40;

} 

 }

//单选框点击

-(void)selectTransType:(id)sender

{


//单选钮

UIImage *selecticonNo =[UIImage imageNamed:SelecticonNo];

UIImage *selecticon =[UIImage imageNamed:Selecticon];

UIButton *btn=nil;


for (int i=1;i<5;i++) {

btn = (UIButton *)[mainZone viewWithTag:i];   //获取单选按钮  mainZone 是最外层的视图

if ([btn isSelected]) {

[btn setBackgroundImage:selecticonNo forState:UIControlStateNormal];

[btn setSelected:NO];

}

}

[sender setBackgroundImage:selecticon forState:UIControlStateSelected]; 

[sender setSelected:YES];

}
