针对iOS10不跳转问题,其实iOS提供了一套未公开方法。但审核是一个问题,不过我们可以想办法绕过审核。
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];
利用ASCII值进行拼装组合方法。这样可绕过审核。
-(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;
}
上面是进入蓝牙界面的方法。也可以有其他的页面可以跳转。设置页面是@"@"Prefs:root=TETHERING",wifi是@"Prefs:root=WIFI"。注意Prefs的P是大写。这么写也有弊端,如果苹果的未公开方法一旦修改。我们必须重新进行修改。

在操作之前, 你需要info中设置 URLTypes, 如下图所示
直接通过 root=* 什么来配置
NSArray *dataArray = @[
@{@"系统设置":@"prefs:root=INTERNET_TETHERING"},
@{@"WIFI设置":@"prefs:root=WIFI"},
@{@"蓝牙设置":@"prefs:root=Bluetooth"},
@{@"系统通知":@"prefs:root=NOTIFICATIONS_ID"},
@{@"通用设置":@"prefs:root=General"},
@{@"显示设置":@"prefs:root=DISPLAY&BRIGHTNESS"},
@{@"壁纸设置":@"prefs:root=Wallpaper"},
@{@"声音设置":@"prefs:root=Sounds"},
@{@"隐私设置":@"prefs:root=privacy"},
@{@"APP Store":@"prefs:root=STORE"},
@{@"Notes":@"prefs:root=NOTES"},
@{@"Safari":@"prefs:root=Safari"},
@{@"Music":@"prefs:root=MUSIC"},
@{@"photo":@"prefs:root=Photos"}
];
如果要跳转本应用的设置界面中,使用prefs:root=boundleId的方式,bundled是应用的bundled
像这样, 我直接调到本应用的通知设置界面
{@"应用通知":@"prefs:root=NOTIFICATIONS_ID&path=boundleId"}
通过添加path路径的方式进行
NSArray *dataArray0 = @[
@{@"关于本机":@"prefs:root=General&path=About"},
@{@"软件升级":@"prefs:root=General&path=SOFTWARE_UPDATE_LINK"},
@{@"日期时间":@"prefs:root=General&path=DATE_AND_TIME"},
@{@"Accessibility":@"prefs:root=General&path=ACCESSIBILITY"},
@{@"键盘设置":@"prefs:root=General&path=Keyboard"},
@{@"VPN":@"prefs:root=General&path=VPN"},
@{@"壁纸设置":@"prefs:root=Wallpaper"},
@{@"声音设置":@"prefs:root=Sounds"},
@{@"隐私设置":@"prefs:root=privacy"},
@{@"APP Store":@"prefs:root=STORE"},
@{@"还原设置":@"prefs:root=General&path=Reset"}
];
之后使用openURL
方法
NSURL *url = [NSURL URLWithString:[dataArray0[11] objectForKey:@"应用通知"]];
if ([UIDevice currentDevice].systemVersion.floatValue <= 10.0) {
[[UIApplication sharedApplication] openURL:url];
}else{
// iOS10 之后, 比较特殊, 只能跳转到设置界面 , UIApplicationOpenSettingsURLString这个只支持iOS8之后.
NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:^(BOOL success) {
// 还可以跳过success这个bool值进行更加精确的判断.
NSLog(@"跳转成功回调");
}];
}
在iOS10之后还有个值得注意的地方, 如果在跳转设置界面之前, 没有申请某种权限, 跳转之后直接crash
便于测试你可以先获取一下通知权限.
if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 8) {
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
}
更多参数配置, 可以在应用中加入更多的设置需求.

iOS开发中有时候有这样的需求:当用户设置不允许访问照片、麦克风和相机等系统权限的时候,这时需要直接跳转到系统的隐私界面进行设置。
前面已经说过,我们需要在用户不允许访问的时候跳转,那么首先我们就要判断一些是否已经开启系统相机权限了。
需要:#import
代码如下:
int author = [ALAssetsLibrary authorizationStatus];
NSLog(@"author type:%d",author);
if(author == ALAuthorizationStatusRestricted || author == ALAuthorizationStatusDenied) {
// The user has explicitly denied permission for media capture. UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"无法使用相册" message:@"请在iPhone的\"设置-隐私-照片\"中允许访问照片。" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alert show]; return;
ALAssetsLibrary类是代表系统中整个资源库,使用它可以访问资源库中的资源和保存照片,视频等功能。
//判断当前应用是否能访问相册资源
/*
typedef NS_ENUM(NSInteger, ALAuthorizationStatus) {
ALAuthorizationStatusNotDetermined = 0, 用户尚未做出了选择这个应用程序的问候
ALAuthorizationStatusRestricted, 此应用程序没有被授权访问的照片数据。可能是家长控制权限。
ALAuthorizationStatusDenied, 用户已经明确否认了这一照片数据的应用程序访问.
ALAuthorizationStatusAuthorized 用户已授权应用访问照片数据.
}
*/
需要:#import
代码如下:
if(isIOS7AndLater) {
NSString *mediaType = AVMediaTypeVideo;// Or AVMediaTypeAudio
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType]; NSLog(@"---cui--authStatus--------%d",authStatus); // This status is normally not visible—the AVCaptureDevice class methods for discovering devices do not return devices the user is restricted from accessing. if(authStatus ==AVAuthorizationStatusRestricted){ NSLog(@"Restricted"); }else if(authStatus == AVAuthorizationStatusDenied){ // The user has explicitly denied permission for media capture. NSLog(@"Denied"); //应该是这个,如果不允许的话 UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"请在设备的\"设置-隐私-相机\"中允许访问相机。" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alert show]; return; } else if(authStatus == AVAuthorizationStatusAuthorized){//允许访问 // The user has explicitly granted permission for media capture, or explicit user permission is not necessary for the media type in question. NSLog(@"Authorized"); }else if(authStatus == AVAuthorizationStatusNotDetermined){ // Explicit user permission is required for media capture, but the user has not yet granted or denied such permission. [AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) { if(granted){//点击允许访问时调用 //用户明确许可与否,媒体需要捕获,但用户尚未授予或拒绝许可。 NSLog(@"Granted access to %@", mediaType); } else { NSLog(@"Not granted access to %@", mediaType); } }]; }else { NSLog(@"Unknown authorization status"); } }
代码如下:
//检测麦克风功能是否打开
[[AVAudioSessionsharedInstance]requestRecordPermission:^(BOOL granted) {
if (!granted)
{
[ViewUtilalertViewWithString:NSLocalizedString(@"麦克风功能未开启",nil)]; } else { [selfrecord:sender]; } }];
判断权限是否设置之后就可以在相应的代理方法进行界面跳转了,那么如何进行跳转呢?
首先要在项目中的info.plist中添加 URL types 并设置一项URL Schemes为prefs,如下图:
实现代码如下:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];//url为具体路径
隐私->照片界面
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Privacy&path=PHOTOS"]];
隐私->相机界面
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Privacy&path=CAMERA"]];
蓝牙设置界面
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Bluetooth"]];
