iOS基础-蓝牙功能项目开发教程

最近做了几个蓝牙项目,写一下过程,方便大家。

本文章介绍手机为*设备的情形

第一步 遵循代理

@interface dbblemanager ()

第二步 设置蓝牙属性

@property (nonatomic ,strong)cbcentralmanager *mycentralmanager;

第三步 实例化

_mycentralmanager = [[cbcentralmanager alloc]initwithdelegate:self queue:nil options:nil];

第四步 实现代理方法

- (void)centralmanagerdidupdatestate:(cbcentralmanager *)central
{
    if (central.state == cbcentralmanagerstatepoweredon) {
        nslog(@"蓝牙已打开");
        nsdictionary *options = [nsdictionary dictionarywithobjectsandkeys:[nsnumber  numberwithbool:yes], cbcentralmanagerscanoptionallowduplicateskey, nil];
        扫描
        [_mycentralmanager scanforperipheralswithservices:nil options:options];
    }else {
        nslog(@"蓝牙已关闭");
        nsurl  *url=[nsurl urlwithstring:@"prefs:root=bluetooth"];
        [[uiapplication sharedapplication]openurl:url];
        [dbtipview progresshud:@"设置-蓝牙-打开蓝牙"];
    }
}

第五步 代理返回蓝牙外设 连接

- (void)centralmanager:(cbcentralmanager *)central diddiscoverperipheral:(cbperipheral *)peripheral advertisementdata:(nsdictionary *)advertisementdata rssi:(nsnumber *)rssi
{
              [_mycentralmanager connectperipheral:peripheral options:nil];
}

第六步

 连接上蓝牙
- (void)centralmanager:(cbcentralmanager *)central didconnectperipheral:(cbperipheral *)peripheral
{
       [_mycentralmanager stopscan];    
}
//连接失败
- (void)centralmanager:(cbcentralmanager *)central didfailtoconnectperipheral:(cbperipheral *)peripheral error:(nullable nserror *)error{
}

//失去连接
-(void)centralmanager:(cbcentralmanager *)central diddisconnectperipheral:(cbperipheral *)peripheral error:(nserror *)error{

}

接下来会开放一个 蓝牙的简单封装。
