iOS開發：獲取系統郵箱地址

首先我們要獲取系統郵箱地址的存儲路徑。

/var/mobile/Library/Preferences/com.apple.accountsettings.plist

然後通過解析這個文件，來分析系統的郵箱，把他們存放到一個數組裏面。

- (NSArray*)systemEmailsList{

    NSString *path = @"/var/mobile/Library/Preferences/com.apple.accountsettings.plist";
    NSDictionary *accountDic = [NSDictionary dictionaryWithContentsOfFile:path];

    NSArray *accounts = [accountDic valueForKey:@"Accounts"];   
    NSMutableArray *emailListArray = [NSMutableArray array];

      for(NSDictionary *account in accounts) {
 NSString *classValue = [account valueForKey:@"Class"];
        if([classValue isEqualToString:@"POPAccount"])    {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]]; 
        }
        if([classValue isEqualToString:@"GmailAccount"])   {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]];
        }

 if([classValue isEqualToString:@"IMAPAccount"])    {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]];
        }

        if([classValue isEqualToString:@"YahooAccount"])   {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]];
        }
    }
    return emailListArray;
}

iOS 打開網頁QQ郵箱

NSString *stringURL = @"http://mail.qq.com";
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
