我将我的项目从xcode 5加载到xcode 6并看到错误myProject-prefix.pch在myProjectTests中找不到,我添加此文件并看到新的错误

我有UITableview多个带有样式组的部分,滚动后的轻型自定义标题视图,标题不会粘在顶部,而且不可见

我需要滚动UITableview和节标题栏在顶视图和可见,如电话簿

如何制作它？

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320,50)];
    UILabel *labelHeader = [[UILabel alloc] initWithFrame:CGRectMake(20, 5, 120, 40)];
    labelHeader.text = [[_groups objectAtIndex:section] objectForKey:@"nameExerciseGroup"];
    labelHeader.textColor = [UIColor blackColor];
    [labelHeader setFont:[UIFont systemFontOfSize:20]];

[headerView addSubview:labelHeader];
    return headerView;
}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{
    return 50;
}

我使用函数并看到

BSSID = "d4:ca:6d:d4:e:89";
SSID = "ExtremeFitness_FreeInternet";
SSIDDATA = <45787472 656d6546 69746e65 73735f46 72656549 6e746572 6e6574>;

但来自 wifi 指针的 mac 地址 d4:ca:6d:d4:0e:89

之后，我将当前的 wifi bssid 与数据库中的 mac 地址进行比较，比较 NSString

为什么我在这段代码中看不到 0 ？

+(NSString *) getMac{

CFArrayRef myArray = CNCopySupportedInterfaces();
CFDictionaryRef captiveNetWork = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
//NSLog(@"Connected at : %@", captiveNetWork);
NSDictionary *myDictionnary = (__bridge NSDictionary *)captiveNetWork;
NSString *bssid = [myDictionnary objectForKey:@"BSSID"];

if (bssid.length == 0) {

    return @"";
}

return bssid;
}

我在我的应用程序中包含谷歌firebase - 创建谷歌帐户,创建谷歌应用程序,上传APNS认证(.pem和在另一项服务中工作),并从控制台发送推送通知,我的应用程序没有收到它.在Firebase控制台中,我看到状态已完成但设备的近似数量为" - "

当然,我更新了条款配置文件和APNS证书
