iOS小demo之跳转系统页面和APPStore

1、跳转到APPStore应用：

[[UIApplication
sharedApplication] openURL:[NSURL
URLWithString:@"itms-apps://itunes.apple.com/cn/app/idxxxxxxxxx"]];(xxxxxxxx为自己的appid);

查看应用的appid：获取APPStore上的APPID

2、跳转系统设置界面：

NSURL*url = [NSURLURLWithString:UIApplicationOpenSettingsURLString];
if([[UIApplicationsharedApplication]canOpenURL:url]) {    

[[UIApplicationsharedApplication]openURL:url];
}
