(目标C)在没有撰写屏幕的情况下打开默认的Apple Mail应用程序，Yahoo Mail或Safari吗? [英] (Objective C) Open default Apple Mail app, Yahoo Mail or Safari without compose screen?

问题描述

我有一个按钮，单击该按钮后，我们可以在默认邮件应用，雅虎邮件和Safari中选择要阅读收件箱的按钮.目前，我正在使用:

I have a button that when it is clicked, It will let us choose between default mail app, yahoo mail and Safari to read inbox. Currently i'm using:

NSURL* mailURL = [NSURL URLWithString:@"mailto:[e-mail]&subject=My%20Subject%20Line&body=Hello%20Email!"];
[[UIApplication sharedApplication] openURL: mailURL];

此代码始终打开撰写屏幕.我不希望它显示出来.我只想打开收件箱，或者只打开邮件应用程序.我该如何实施?非常感谢你！

This code always open the compose screen. I don't want it be shown. I just want to open inbox or just only open the mail app. How can I implement that? Thank you very much!

更新

我知道现在如何在不显示屏幕的情况下打开应用程序.

I know how to open app without compose screen now.

如果要打开默认邮件应用程序，请使用:

If you want to open default mail app, use:

NSURL* mailURL = [NSURL URLWithString:@"message://"];

如果要打开Gmail，请使用:

If you want to open Gmail, use:

NSString *gmailUrl = @"googlegmail://";

现在的问题是:如何显示一个对话框以在它们之间进行选择

Now the problem is: How to show a dialog to choose between them
