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。
