iOS系統(tǒng)權(quán)限檢測(cè)（定位、相機(jī)、相冊(cè)、麥克風(fēng)、通知）

2018.01.18更新

近日遇到通過xcode的upload to AppStrore 上傳成功后，在iTunes的MyApps中找不到構(gòu)建的版本～，后面通過查詢資料才知道。是因?yàn)樯暾?qǐng)對(duì)應(yīng)權(quán)限時(shí)沒有在value中填寫對(duì)應(yīng)內(nèi)容引起的～～markmarkmark。蠢哭了

原文

由于蘋果對(duì)于獲取用戶隱私權(quán)限的嚴(yán)格控制，在獲取用戶相機(jī)/相冊(cè)/位置/通知等權(quán)限時(shí)，必須由用戶手動(dòng)授權(quán)之后方可獲取。故事，就是在這樣的場(chǎng)景下開始的...

一、權(quán)限設(shè)置

Q：獲取對(duì)應(yīng)權(quán)限需要做些什么？

A：需要在info.plist中預(yù)設(shè)對(duì)應(yīng)權(quán)限key值，如下

Privacy - Camera Usage Description -> 相機(jī)

Privacy - Microphone Usage Description -> 麥克風(fēng)

Privacy - Photo Library Usage Description -> 讀取相冊(cè)
Privacy - Photo Library Additions Usage Description -> 保存圖片至相冊(cè)

Privacy - NSLocationAlwaysUsageDescription -> 始終獲取地理位置
Privacy - NSLocationWhenInUseUsageDescription -> 使用時(shí)獲取地理位置

PS：位置授權(quán)二選一即可

在使用對(duì)應(yīng)功能如調(diào)起相冊(cè)時(shí)系統(tǒng)會(huì)彈框要求用戶授權(quán)。

二、授權(quán)狀態(tài)檢測(cè)

Q：如果用戶沒有同意授權(quán)或拒絕授權(quán)，如何保證在使用相關(guān)功能時(shí)提示用戶開啟權(quán)限？

A：需要檢測(cè)對(duì)應(yīng)權(quán)限狀態(tài)，

如果用戶未授權(quán)---->提示用戶授權(quán)（系統(tǒng)行為）

如果用戶之前拒絕授權(quán)---->提示用戶開啟授權(quán)（App實(shí)現(xiàn)）

如下

       if(granted)
        {
            if (authorizedBlock)

        }}];
   }

        {
            isAvalible = NO;
        
            //提示用戶開啟通知權(quán)限
            [SystemManager openSettingPagewithMessage:@"通知"];
        }
        else

        }
    }


    return isAvalible;

定位權(quán)限<支持8.0+>
 +(BOOL)detectionLocationState:(void(^)())authorizedBlock

               if([CLLocationManager locationServicesEnabled])      
               {
    
                    if(!_locationManager)
                    {
                        _locationManager = [[CLLocationManager alloc] init];
        
                        if([_locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])
                        {
                            [_locationManager requestWhenInUseAuthorization];
                         }
        
                        //設(shè)置代理
                        [_locationManager setDelegate:self];
                        //設(shè)置定位精度
                        [_locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
                        //設(shè)置距離篩選
                        [_locationManager setDistanceFilter:100];
                        [_locationManager startUpdatingHeading];
                    } 
                    else 
                    {
                        //開始定位
                        [_locationManager startUpdatingLocation];
                    }
           }
           else
           {
               //提示用戶打開定位權(quán)限
               [SystemManager openSettingPagewithMessage:@"定位"];
           }
        }
        //用戶已經(jīng)授權(quán)
        else if (authStatus == kCLAuthorizationStatusAuthorizedAlways||authStatus == kCLAuthorizationStatusAuthorizedWhenInUse)
        {
            isAvalible = YES;
        
            if (authorizedBlock)
            {
                authorizedBlock();
            }
        }
        //用戶決絕授權(quán)
        else
        {
            //提示用戶打開定位權(quán)限
            [SystemManager openSettingPagewithMessage:@"定位"];
        }
    }


    return isAvalible;

}

三、設(shè)置頁面跳轉(zhuǎn)

Q：提示用戶需要打開對(duì)應(yīng)權(quán)限，能否可以直接跳轉(zhuǎn)到對(duì)應(yīng)開關(guān)頁面？

A：iOS8之后是可以的

跳轉(zhuǎn)到設(shè)置界面

+(void)openSettingPagewithMessage:(NSString *)message
{
    if (iOS8OrLater)
    {
         [[SystemManager shareManager] showSystemAlertwithTitle:@"提示" message:[NSString stringWithFormat:@"為了更好的體驗(yàn)功能，請(qǐng)到設(shè)置頁面->隱私->%@，將XX對(duì)應(yīng)開關(guān)開啟",message] cancelButtonTitle:@"下次提醒" otherButtonTitles:@"去設(shè)置" baseController:nil resultBlock:^(NSInteger index) {
        
            if (index == 1)
            {
                NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
                if ([[UIApplication sharedApplication] canOpenURL:url])
                {
                    [[UIApplication sharedApplication] openURL:url];
                }
            }
        
        }];
    
    }
    //iOS8以下
    else
    {
        [[SystemManager shareManager] showSystemAlertwithTitle:@"提示" message:[NSString stringWithFormat:@"為了更好的體驗(yàn)功能，請(qǐng)到設(shè)置頁面->隱私->%@，將XX對(duì)應(yīng)開關(guān)開啟",message] cancelButtonTitle:@"我知道了" otherButtonTitles:nil baseController:nil resultBlock:nil];
    }

}

XX為App的名字
