UIActivity
函数有问题。
首先,我创建了3个事件项:
activityDownload
activityTrash
activityMove
.并添加到 UIActivityViewController
然后,当我展示包含上述 3 项的 UIActivityViewController
时。好的,这里没问题。
然后,当我单击“更多”按钮并对项目进行排序时,例如,我将“移动”按钮移到顶部,
单击“完成”按钮后,我不知道为什么下载,垃圾邮件丢失了?
移动项目仅显示在 AirDrop 菜单 View 中。
NSURL *url = [self fileToURL:self.documentName];
NSArray *objectsToShare = @[url];
AirDropActivityView *activityDownload = [[AirDropActivityView alloc] init];
activityDownload.airDropType = 0;
AirDropActivityView *activityTrash = [[AirDropActivityView alloc] init];
activityTrash.airDropType = 1;
AirDropActivityView *activityMove = [[AirDropActivityView alloc] init];
activityMove.airDropType = 2;
NSArray *uiActivitys = @[activityDownload,activityTrash,activityMove];
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItemsbjectsToShare applicationActivities:uiActivitys];
// Exclude all activities except AirDrop.
NSArray *excludedActivities = @[UIActivityTypePostToTwitter, UIActivityTypePostToFacebook, UIActivityTypePostToWeibo,UIActivityTypeMessage,UIActivityTypePrint, UIActivityTypeCopyToPasteboard UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll,UIActivityTypeAddToReadingList, UIActivityTypePostToFlickr,UIActivityTypePostToVimeo,UIActivityTypePostToTencentWeibo];
controller.excludedActivityTypes = excludedActivities;
// Present the controller
[self presentViewController:controller animated:YES completion:nil];

请看截图:
这可能是您使用的所有自定义 UIActivity View 具有相同的 activityType
会导致此问题。
所以我建议为您要使用的每个 View 创建更多的自定义 UIActivity
。像这样:
创建AirDropActivityView1
;
在AirDropActivityView1.m
中,实现:
#import "AirDropActivityView1.h"
@implementation AirDropActivityView
- (NSString *)activityType
{
return @"youapp.Activity1";
}
- (NSString *)activityTitle
{
return @"Activity1";
}
- (BOOL)canPerformWithActivityItemsNSArray *)activityItems
{
return YES;
}
@end
与 AirDropActivityView2.m
#import "AirDropActivityView2.h"
@implementation AirDropActivityView
- (NSString *)activityType
{
return @"youapp.Activity2";
}
- (NSString *)activityTitle
{
return @"Activity2";
}
- (BOOL)canPerformWithActivityItemsNSArray *)activityItems
{
return YES;
}
@end
最后:
AirDropActivityView1 *activity1 = [[AirDropActivityView1 alloc] init];
AirDropActivityView2 *activity2 = [[AirDropActivityView2 alloc] init];
NSArray *uiActivitys = @[activity1,activity2];
现在您可以重新排序。 希望对您有所帮助。
