单击电子邮件地址时设置默认主题 [英] Set default subject when click on email address
问题描述
我正在使用带有UITextView.code的dataDetectorTypes属性。
I am using dataDetectorTypes property with UITextView.code works fine.
当我点击链接时，电子邮件编辑器会出现预填充的To：[email address]但是我想要设置默认主题：[主题字符串]。
When I click on link email composer appears with pre-filled To:[email address] but i want to set default Subject:[subject string] also.
我该怎么做？
推荐答案
1）拳头将< UITextViewDelegate，MFMailComposeViewControllerDelegate> 添加到包含textview的类中。
1)Fist add <UITextViewDelegate, MFMailComposeViewControllerDelegate> to the class that contains the textview.
您必须向此类添加两个导入：
You must add two imports to this class:
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
2）添加变量： MFMailComposeViewController （在这个示例mailVC中，您还可以将其添加为.h）中的类属性。
2) Add a variable: MFMailComposeViewController (in this example mailVC, you can also add it as a class property in your .h)
3）实现下一个方法：
3) Implement the next method:
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange
这允许拦截特定的网址交互。您可以取消特定的交互并添加自己的操作，例如：
This allows to intercepts the specific url interaction. You can cancel a specific interaction and add your own action, for example:
-(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange{
//EXAMPLE CODE
if ([[URL scheme] isEqualToString:@"mailto"]) {
mailVC = [[MFMailComposeViewController alloc] init];
[mailVC setToRecipients:@[@"your@destinationMail.com"]];
[mailVC setSubject:@"A subject"];
mailVC.mailComposeDelegate = self;
[self presentViewController:mailVC animated:YES completion:^{
// [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}];
return NO;
}
return YES;
}
3）要关闭你的MFMailComposeViewController变量：
3) To dismiss your MFMailComposeViewController variable:
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
[mailVC dismissViewControllerAnimated:YES completion:nil];
}
这对我有用！
