I see via sharing content from other apps that it is possible to set a different subject and body when using share sheet to share into the Gmail Mail app. I have implemented it and it works fine on the native mail app but not Gmail.
Going into Yelp and sharing a business then choosing gmail from the share sheet, I see that the subject and body are different. The subject contains the address of the business while the body contains the address + a link to the business on Yelp.
I have tried to replicate this logic with success on the native Mail app but not in the Gmail app.
I have tried the following:
Implementing UIActivityItemSource methods
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[self] applicationActivities:nil]; - (id)activityViewControllerPlaceholderItem:(UIActivityViewController *)activityViewController { return @""; } - (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType { return @"body"; } - (NSString *)activityViewController:(UIActivityViewController *)activityViewController subjectForActivityType:(NSString *)activityType { return @"subject"; } Result
Apple Mail Subject set to "subject", Body set to "body"
Gmail Subject set to "body", Body set to "body"
- (NSString *)activityViewController:(UIActivityViewController *)activityViewController subjectForActivityType:(NSString *)activityType Is never called when sharing into the Gmail app.
I then try the more hack way of doing it
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[@"body"] applicationActivities:nil]; [activityViewController setValue:@"subject" forKey:@"subject"]; Result
Apple Mail Subject set to "subject", Body set to "body"
Gmail Subject set to "body", Body set to "body"
Any way to make Gmail Behave like Apple Mail?
Again, I have seen that other applications like Yelp and Safari have gotten the proper behavior out of the Gmail app through share sheet. Any advice would be appreciated, thanks.

[_activityViewController setValue:subject forKey:@"subject"];-Not supported way.
Correct way to set body and subject (iOS 7.0 and later) - implement UIActivityItemSource protocol on item to share.
// EmailDataProvider.h @interface EmailItemProvider : NSObject <UIActivityItemSource> @property (nonatomic, strong) NSString *subject; @property (nonatomic, strong) NSString *body; @end // EmailDataProvider.m @implementation EmailDataProvider - (id)activityViewControllerPlaceholderItem:(UIActivityViewController *)activityViewController { return _body; } - (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType { return _body; } - (NSString *)activityViewController:(UIActivityViewController *)activityViewController subjectForActivityType:(NSString *)activityType { return _subject; } @end And than present it:
EmailDataProvider *emailItem = [[EmailDataProvider alloc]init]; emailItem.subject = @"This is Subject text."; emailItem.body = @"This is Body,set by programatically"; UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[emailItem] applicationActivities:nil]; [self presentViewController:activityViewController animated:YES completion:nil];
