iOS 跳转设置页面

跳转自己 App 设置页

首先你的 App 得有设置，也就是申请过相册、录音等权限才可以

// iOS8+
NSURL *appSettingURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:appSettingURL]) {
   [[UIApplication sharedApplication] openURL:appSettingURL];
}

跳转系统设置页

NSURL *keyboardSettingURL = [NSURL URLWithString:@"App-Prefs:root=General&path=Keyboard"];
if ([[UIApplication sharedApplication] canOpenURL:keyboardSettingURL]) {
    [[UIApplication sharedApplication] openURL:keyboardSettingURL];
}
