因为某些业务需要 app需要调到系统设置页面:
- 方法一
NSURL *url = [NSURLURLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplicationsharedApplication] canOpenURL:url]) {
//如果点击打开的话，需要记录当前的状态，从设置回到应用的时候会用到
[[UIApplicationsharedApplication] openURL:url];
}
-
方法二
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]]
- 附录
