1.跳转到AppStore评分
应用地址是关键:IOS 设备,手机搜索应用,拷贝链接
NSString *appStr =@"https://itunes.apple.com/cn/app/%E9%91%AB%E5%AE%A2%E9%80%9A/id1227457584?mt=8"
"
;
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:appStr]];
2.应用中调用系统写邮件
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"mailto:example@example.com"]];
