私有API-iOS10 openURL方法跳转到设置界面失效的解决方法

http://www.jianshu.com/p/ee666b21e0a9

解决方法

可以使用MobileCoreServices.framework里的私有API:

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

头文件参考：LSApplicationWorkspace.h

使用方法：

//注意首字母改成了大写，prefs->Prefs

NSURL*url=[NSURLURLWithString:@"Prefs:root=Privacy&path=LOCATION"];

Class LSApplicationWorkspace =NSClassFromString(@"LSApplicationWorkspace");

[[LSApplicationWorkspace performSelector:@selector(defaultWorkspace)] performSelector:@selector(openSensitiveURL:withOptions:) withObject:url withObject:nil];

MobileCoreServices.framework不是私有库，所以直接使用performSelector:即可调用私有API

注意

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。

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，绕过审核。例如这位仁兄用ASCII混淆的方法：

- (UIView*)statusBarView {

UIView*statusBar =nil;

NSData*data = [NSDatadataWithBytes:(unsignedchar[]){0x73,0x74,0x61,0x74,0x75,0x73,0x42,0x61,0x72} length:9];

NSString*key = [[NSStringalloc] initWithData:data encoding:NSASCIIStringEncoding];

id object = [UIApplicationsharedApplication];

if([object respondsToSelector:NSSelectorFromString(key)])

 {        

statusBar = [object valueForKey:key];    

 }

returnstatusBar;

 }

不过，还是不建议使用私有API，因为它是不可靠的。也许某天苹果就把它移除了。
