Question

所以到目前为止我创建了两个文本字段，文本字段连接到邮件编辑器，用户在其中写入的内容是邮件编写器中出现的内容但是我不知道如何为邮件编写器执行相同操作UIImageView，我希望用户选择一张图片或拍照，并自动添加到邮件编辑器中。

@interface xyzViewController ()

@end

@implementation xyzViewController


- (IBAction)savedata:(id)sender; {
NSString *savestring = _mytextview.text;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:savestring forKey:@"savedstring"];
[defaults synchronize];

NSString *savestring1 = _mytextview1.text;
NSUserDefaults *defaults1 = [NSUserDefaults standardUserDefaults];
[defaults1 setObject:savestring1 forKey:@"savedstring1"];
[defaults synchronize];

}

- (IBAction)loaddata:(id)sender; {

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *loadstring = [defaults objectForKey:@"savedstring"];
[_mytextview setText:loadstring];
[label setText:loadstring];

NSUserDefaults *defaults1 = [NSUserDefaults standardUserDefaults];
NSString *loadstring1 = [defaults objectForKey:@"savedstring1"];
[_mytextview1 setText:loadstring1];

}

- (IBAction)dismiss:(id)sender {
[sender resignFirstResponder];
}
- (IBAction)dismiss1:(id)sender {
[sender resignFirstResponder];
}

当然，如果您使用的是MFMailComposeViewController课程，则可以将图片附加到邮件中。

您只需要弄清楚如何使用"addAttachmentData: mimeType: fileName:"的API。
