1. 声明全局变量
UIView *headView; 表头部View
UIButton *financeBtn; //金融头条Btn
UIButton *companyNewsBtn;//公司新闻Btn
2.在viewDidLoad里面
- (void)viewDidLoad {
[super viewDidLoad];
float screenWidth = kUIScreenWidth -70;
financeBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[financeBtn setTitle:@"金融头条" forState:UIControlStateNormal];
[financeBtn.titleLabel setFont:[UIFont fontWithName:kPingFang_Medium size:14]];
[financeBtn setFrame:CGRectMake(screenWidth/4-40, 12, 80, 25)];
[financeBtn setTitleColor:[CommonFunctions colorWithHex:0x11a1b4] forState:UIControlStateNormal];
[financeBtn setTag:222];
[financeBtn addTarget:self action:@selector(companyNewsBtnClick:) forControlEvents:UIControlEventTouchUpInside];
companyNewsBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[companyNewsBtn setTitle:@"公司新闻" forState:UIControlStateNormal];
[companyNewsBtn.titleLabel setFont:[UIFont fontWithName:kPingFang_Medium size:14]];
[companyNewsBtn setFrame:CGRectMake((screenWidth/2)+(screenWidth/4-40), 12, 80, 25)];
[companyNewsBtn setTitleColor:[CommonFunctions colorWithHex:0x999999] forState:UIControlStateNormal];
[companyNewsBtn addTarget:self action:@selector(companyNewsBtnClick:) forControlEvents:UIControlEventTouchUpInside];
[companyNewsBtn setTag:333];
}
3. 区头设置 在方法里面判断不让按钮循环创建
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
headView = [[UIView alloc] initWithFrame:CGRectMake(0, -1, kUIScreenWidth, 69)];
headView.backgroundColor = [UIColor whiteColor];
if(section == 0) {
UIButton *mergeBtn = (UIButton *)[self.view viewWithTag:222];
if (mergeBtn == nil) {
[headView addSubview:financeBtn];
[headView addSubview:companyNewsBtn];
}
}
return headView;
}
4. 实现按钮的点击方法就OK了
#pragma mark 金融头条和公司新闻 Btn
- (void)companyNewsBtnClick:(UIButton *)sender {
float screenWidth = kUIScreenWidth -70;
UIButton *changeBtn = (UIButton *)[self.view viewWithTag:sender.tag];
[changeBtn setTitleColor:[CommonFunctions colorWithHex:0x11a1b4] forState:UIControlStateNormal];
if (sender.tag == 222) {
NSLog(@"金融头条");
picImg.frame = CGRectMake(screenWidth/4-40, -1, 80, 4);
[companyNewsBtn setTitleColor:[CommonFunctions colorWithHex:0x999999] forState:UIControlStateNormal];
}else if (sender.tag == 333) {
NSLog(@"公司新闻");
picImg.frame = CGRectMake((screenWidth/2)+(screenWidth/4-40), -1, 80, 4);
[financeBtn setTitleColor:[CommonFunctions colorWithHex:0x999999] forState:UIControlStateNormal];
}
}
效果图 如下：
