一、跳转到“设置”

//>=iOS8.0可用

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

二、跳转到设置的其它位置

1. 首先针对Info.plist添加如下选项

2. 调用跳转代码，如下

//跳转到“About”(关于本机)页面  
NSURL *url = [NSURL URLWithString:@"prefs:root=General&path=About"];  
if ([[UIApplication sharedApplication] canOpenURL:url]) {  
    [[UIApplication sharedApplication] openURL:url];  
} else {  
    NSLog(@"can not open");  
}

三. 附，“设置”中各个页面的“地址”
