UIActivityViewController是iOS原生彈窗式分享

UIActivityViewController的使用

// 1、設(shè)置分享的內(nèi)容，并將內(nèi)容添加到數(shù)組中
    UIImage *shareImage = [UIImage imageNamed:@"shareImage.png"];
    NSURL *shareUrl = [NSURL URLWithString:@"http://www.itdecent.cn/u/e12f189a320d"];
    NSArray *activityItemsArray = @[shareImage,shareUrl];

    // 自定義的CustomActivity，繼承自UIActivity
    CustomActivity *customActivity = [[CustomActivity alloc]initWithTitle:@"" ActivityImage:[UIImage imageNamed:@"custom.png"] URL:shareUrl ActivityType:@"Custom"];
    NSArray *activityArray = @[customActivity];

    // 2、初始化控制器，添加分享內(nèi)容至控制器
    UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItemsArray applicationActivities:activityArray];
    activityVC.modalInPopover = YES;
     NSMutableArray *excludeArray = [@[UIActivityTypeAirDrop,UIActivityTypeMessage,UIActivityTypePrint,UIActivityTypePostToTwitter,UIActivityTypePostToFacebook,UIActivityTypeOpenInIBooks,UIActivityTypePostToVimeo,UIActivityTypePostToFlickr,UIActivityTypeAddToReadingList,UIActivityTypeSaveToCameraRoll,UIActivityTypeAssignToContact,UIActivityTypeCopyToPasteboard,UIActivityTypeMail] mutableCopy];
    activityVC.excludedActivityTypes = excludeArray;
    // 3、設(shè)置回調(diào)
    if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {
        // ios8.0 之后用此方法回調(diào)
        UIActivityViewControllerCompletionWithItemsHandler itemsBlock = ^(UIActivityType __nullable activityType, BOOL completed, NSArray * __nullable returnedItems, NSError * __nullable activityError){
            NSLog(@"activityType == %@",activityType);
            if (completed == YES) {
                NSLog(@"completed");
                
            }else{
                NSLog(@"cancel");
            }
        };
        activityVC.completionWithItemsHandler = itemsBlock;
    }else{
        // ios8.0 之前用此方法回調(diào)
        UIActivityViewControllerCompletionHandler handlerBlock = ^(UIActivityType __nullable activityType, BOOL completed){
            NSLog(@"activityType == %@",activityType);
            if (completed == YES) {
                NSLog(@"completed");
            }else{
                NSLog(@"cancel");
            }
        };
        activityVC.completionHandler = handlerBlock;
    }
    // 4、調(diào)用控制器
    [self presentViewController:activityVC animated:YES completion:nil];
