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];
}
补充：移动开发 , IOS ,
