iOS10跳转至设置页面

在iOS10之前，跳转到系统设置界面的某个指定界面的方式如下：

//打开定位服务界面
NSURL*url=[NSURL URLWithString:@"prefs:root=Privacy&path=LOCATION"];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL:url];
};
但是在iOS10上，调用canOpenURL:打开系统设置界面时控制台会报如下错误，并且无法跳转：

-canOpenURL: failed for URL: "Prefs:root=Privacy&path=LOCATION" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

原因是iOS10只允许跳转到设置里自己app的界面，对跳转到其他界面做了限制.

 

解决方法

1跳转到设置里自己app的界面:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

2可以使用MobileCoreServices.framework里的私有API:

- (BOOL)openSensitiveURL:(id)arg1 withOptions:(id)arg2;

//注意首字母改成了大写，prefs->Prefs
NSURL*url=[NSURL URLWithString:@"Prefs:root=Privacy&path=LOCATION"];
Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");
[[LSApplicationWorkspace performSelector:@selector(defaultWorkspace)] performSelector:@selector(openSensitiveURL:withOptions:) withObject:url withObject:nil];

• iOS10的系统URLScheme改成了首字母大写，使用小写的方式会无法打开。
• app需要添加一个Prefs的URL Schemes，即添加到info.plist的LSApplicationQueriesSchemes项中。
• 使用私有API的app无法通过App Store审核。你也可以尝试把私有类名和selector字符串混淆一下，采用ASC码绕过审核。

例如:

    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];

 

//采用ASC码输出defaultWorkspace-----项目中不要写这条注释

-(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;

}

 //采用ASC码输出openSensitiveURL:withOptions----项目中不要写这条注释

-(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;

}
