教你跳转到系统设置界面

例如跳转到定位服务页面, 跳转代码如下:
	NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
        if ([[UIApplication sharedApplication] canOpenURL:url]) {
            [[UIApplication sharedApplication] openURL:url];
        }

如果出现了以下错误
	/** _BSMachError: (os/kern) invalid capability (20) 和 _BSMachError: (os/kern) invalid name (15) */				可以加一个多线程, 延迟调用
            NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
            dispatch_after(0.2, dispatch_get_main_queue(), ^{
                if ([[UIApplication sharedApplication] canOpenURL:url]) {
                [[UIApplication sharedApplication] openURL:url];
                }
            });

以下是在网上找到的跳转到各个页面的代码:
