我正在使用UIActivityViewController来显示共享。在列表中,当我选择“邮件”应用程序时,主题和正文已正确设置,而在Gmail应用程序中则为空。
- (void)shareAVideoWithSubject:(NSString*)subject Link:(NSString *)string onViewController:(UIViewController *)viewController fromView:(UIView *)view {
_activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:@[string]
applicationActivities:nil];
_activityViewController.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, UIActivityTypeAddToReadingList, UIActivityTypeAirDrop];
[_activityViewController setValue:subject forKey:@"subject"];
UIWindow *window = [[[UIApplication sharedApplication] delegate]window];
//if iPhone
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
if(!viewController){
viewController = ((SWRevealViewController*)window.rootViewController).presentedViewController;
}
[viewController presentViewController:_activityViewController
animated:YES
completion:nil];
}
//if iPad
else
{
// Change Rect to position Popover
popup = [[UIPopoverController alloc] initWithContentViewController:_activityViewController];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:view];
[popup presentPopoverFromBarButtonItem:barButton permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
我在StackOverFlow上检查了以下两个问题。
这些不是我的问题的答案,因为它们在列表中添加了新的 Activity ,而是我希望iOS显示所有可共享的应用程序。在这种情况下,Gmail共享正文将为空。
提前致谢。

最佳答案
[_activityViewController setValue:subject forKey:@"subject"];
是设置电子邮件主题的未公开方法。
设置正文和主题的正确方法(iOS 7.0及更高版本)-在要共享的项目上实现UIActivityItemSource
协议(protocol)。
// EmailItemProvider.h
@interface EmailItemProvider : NSObject <UIActivityItemSource>
@property (nonatomic, strong) NSString *subject;
@property (nonatomic, strong) NSString *body;
@end
// EmailItemProvider.m
#import "EmailItemProvider.h"
@implementation EmailItemProvider
- (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
比介绍它:
EmailItemProvider *emailItem = [EmailItemProvider new];
emailItem.subject = @"Subject";
emailItem.body = @"Body";
UIActivityViewController *activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:@[emailItem]
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];
这将在邮件应用程序上设置正文和主题,但似乎Gmail应用程序会忽略主题并将其设置为正文。
重要:Gmail应用程序似乎有一个错误。传递
&
字符会使消息主题和正文为空。请改用&
。其他特殊字符未经测试。关于ios - UIActivityViewController Gmail共享主题和正文会变空吗?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/29765806/
