iOS 跳转至系统设置页面整理以及绕过审核的跳转方法

示例：项目里面有扫码功能，当用户第一次扫码—选择不允许访问相机，再次使用扫码APP就需要引导用户到系统的相机页面开启相机权限。类似的功能还有定位、录音、蓝牙、相册等，这些功能都需要给用户提示/引导。

根据上述情况，市场上的App有两种做法：

• 不做跳转，给用户提示;
• 给用户提示，并做跳转，引导用户到设置界面； 

总述：

iOS10之前可以进入系统设置的子页面
iOS11之后不允许跳转到设置的子页面，只允许跳转到设置界面(首页)

 
// 跳转到设置 - 相机 / 该应用的设置界面
NSURL *url1 = [NSURL URLWithString:@"App-Prefs:root=Privacy&path=CAMERA"];
// iOS10也可以使用url2访问，不过使用url1更好一些，可具体根据业务需求自行选择
NSURL *url2 = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if (@available(iOS 11.0, *)) {
    if ([[UIApplication sharedApplication] canOpenURL:url2]){
        [[UIApplication sharedApplication] openURL:url2 options:@{} completionHandler:nil];
    }
} else {
    if ([[UIApplication sharedApplication] canOpenURL:url1]){
        if (@available(iOS 10.0, *)) {
            [[UIApplication sharedApplication] openURL:url1 options:@{} completionHandler:nil];
        } else {
            [[UIApplication sharedApplication] openURL:url1];
        }
    }
}

附：iOS 10之前常用的跳转指令（现已经被苹果列为非公开API,有审核风险）

iOS 10 绕过审核进行跳转到蓝牙开关的方法

//亲测iOS 10.3.3 有效
- (void)turnToBluetooth {
     if (iOS_Version <= 10) {
         [self setBlueTooth];
    } else {//@"App-Prefs:root=General&path=Bluetooth"
        NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
        [[UIApplication sharedApplication] openURL:url];
    }
}


-(NSString *) getDefaultWork{
    NSData *dataOne = [NSData dataWithBytes:(unsigned char []){0x64,0x65,0x66,0x61,0x75,0x6c,0x74,0x57,0x6f,0x72,0x6b,0x73,0x70,0x61,0x63,0x65} length:16];
    NSString *method = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];
    return method;
}

-(NSString *) getBluetoothMethod{
    NSData *dataOne = [NSData dataWithBytes:(unsigned char []){0x6f, 0x70, 0x65, 0x6e, 0x53, 0x65, 0x6e, 0x73, 0x69,0x74, 0x69,0x76,0x65,0x55,0x52,0x4c} length:16];
    NSString *keyone = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];
    NSData *dataTwo = [NSData dataWithBytes:(unsigned char []){0x77,0x69,0x74,0x68,0x4f,0x70,0x74,0x69,0x6f,0x6e,0x73} length:11];
    NSString *keytwo = [[NSString alloc] initWithData:dataTwo encoding:NSASCIIStringEncoding];
    NSString *method = [NSString stringWithFormat:@"%@%@%@%@",keyone,@":",keytwo,@":"];
    return method;
}

-(void)setBlueTooth {
    NSString * defaultWork = [self getDefaultWork];
    NSString * bluetoothMethod = [self getBluetoothMethod];
    NSURL*url=[NSURL URLWithString:@"Prefs:root=Bluetooth"];
    Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");
    [[LSApplicationWorkspace performSelector:NSSelectorFromString(defaultWork)] performSelector:NSSelectorFromString(bluetoothMethod) withObject:url withObject:nil];
