需求

應(yīng)用需要定位服務(wù)，如果系統(tǒng)定位服務(wù)未開(kāi)啟，就要跳到系統(tǒng)設(shè)置頁(yè)面。

問(wèn)題

關(guān)于如何跳轉(zhuǎn)，網(wǎng)上有很多好的文章，這里就不贅述了，貼出幾個(gè)鏈接：
1、http://www.itdecent.cn/p/767c409c50e6

等。。。
但是，ios10以后，只能跳到系統(tǒng)設(shè)置里自己應(yīng)用的配置界面，如下

自己應(yīng)用的設(shè)置

系統(tǒng)設(shè)置

解決方法

利用一個(gè)私有API，需要用到的類(lèi)：LSApplicationWorkspace，屬于MobileCoreServices.framework靜態(tài)庫(kù)，關(guān)于這一私有API和runtime的知識(shí)可以查看:http://www.itdecent.cn/p/6167b9ce7af8
代碼

NSString *defaultWork = @"defaultWorkspace";
NSString *bluetoothMethod = @"openSensitiveURL:withOptions:";
Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");
[[LSApplicationWorkspace performSelector:NSSelectorFromString(defaultWork)] performSelector:NSSelectorFromString(bluetoothMethod) withObject:url withObject:nil];

這樣就可以跳轉(zhuǎn)到系統(tǒng)設(shè)置頁(yè)面了。

備注

1、這樣跳轉(zhuǎn)，不是跳轉(zhuǎn)到系統(tǒng)設(shè)置主頁(yè)面，系統(tǒng)設(shè)置頁(yè)面本身在哪個(gè)頁(yè)面，跳轉(zhuǎn)過(guò)去，頁(yè)面會(huì)保持在那個(gè)頁(yè)面，例如你之前操作手機(jī)打開(kāi)了wifi設(shè)置，跳轉(zhuǎn)過(guò)去就是在wifi設(shè)置；
2、根據(jù)我所掌握的知識(shí)，ios10之后，沒(méi)有辦法指定跳轉(zhuǎn)的具體位置，例如你想指定跳轉(zhuǎn)到系統(tǒng)設(shè)置的藍(lán)牙設(shè)置，ios10以后做不到，如果有會(huì)的大神朋友請(qǐng)給我留言！
3、上面的代碼中，@"defaultWorkspace"，@"openSensitiveURL:withOptions:"這些字比較敏感，可能會(huì)影響審核，可以采取NSData轉(zhuǎn)NSString的方式，屏蔽掉那些字段

//@"defaultWorkspace"
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 *defaultWork = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];
//@"openSensitiveURL:withOptions:"
NSData *dataTwo = [NSData dataWithBytes:(unsigned char []){0x6f, 0x70, 0x65, 0x6e, 0x53, 0x65, 0x6e, 0x73, 0x69,0x74, 0x69,0x76,0x65,0x55,0x52,0x4c} length:16];
NSString *keyTwo = [[NSString alloc] initWithData:dataTwo encoding:NSASCIIStringEncoding];
NSData *dataThree = [NSData dataWithBytes:(unsigned char []){0x77,0x69,0x74,0x68,0x4f,0x70,0x74,0x69,0x6f,0x6e,0x73} length:11];
NSString *keyThree = [[NSString alloc] initWithData:dataThree encoding:NSASCIIStringEncoding];
NSString *bluetoothMethod = [NSString stringWithFormat:@"%@%@%@%@",keyTwo,@":",keyThree,@":"];
//私有API跳轉(zhuǎn)
Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");
[[LSApplicationWorkspace performSelector:NSSelectorFromString(defaultWork)] performSelector:NSSelectorFromString(bluetoothMethod) withObject:url withObject:nil];
