有时我们需要调用系统自带分享，可以使用UIActivityViewController:
简单用法代码如下：

    NSMutableArray *items = [[NSMutableArray alloc] init];
    [items addObject:@"分享的title"];
    [items addObject:[UIImage imageNamed:@"1"]];
    [items addObject:@"https://www.baidu.com"];
    
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:nil];
    //NSMutableArray *excludedActivityTypes =  [NSMutableArray arrayWithArray:@[UIActivityTypeAirDrop, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeMail, UIActivityTypePostToTencentWeibo, UIActivityTypeSaveToCameraRoll, UIActivityTypeMessage, UIActivityTypePostToTwitter]];
    //activityViewController.excludedActivityTypes = excludedActivityTypes;
    [self presentViewController:activityViewController animated:YES completion:nil];
    activityViewController.completionWithItemsHandler = ^(UIActivityType __nullable activityType, BOOL completed, NSArray * __nullable returnedItems, NSError * __nullable activityError){
        NSLog(@"%@  ----   %@", activityType, returnedItems);
    };

效果图：

将上面代码两行注释打开效果图：

UIActivityViewController

NS_CLASS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED @interface UIActivityViewController : UIViewController

可以看出UIActivityViewController是在iOS 6开始支持,且继UIViewController

初始化方法

- (instancetype)initWithActivityItems:(NSArray *)activityItems applicationActivities:(nullable NSArray<__kindof UIActivity *> *)applicationActivities

参数：
activityItems：数组内的对象代表的是我们想要操作的数据的一些属性，而且这个数组至少需要一个值，比如我们PDF文档的名称，URL；
applicationActivities：数组指定了泛型，数组内的对象必须是UIActivity类型的对象，代表的是iOS系统支持的我们自定义的服务(后边有讲解)

UIActivityViewController中如果不想显示某些系统自带分享功能，可以使用下面这个属性进行设置，数组中的UIActivityType对象就是不显示的item功能

@property(nullable, nonatomic, copy) NSArray<UIActivityType> *excludedActivityTypes;

UIActivityType类型有如下：

UIKIT_EXTERN UIActivityType const UIActivityTypePostToFacebook     NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToTwitter      NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToWeibo        NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED; 
UIKIT_EXTERN UIActivityType const UIActivityTypeMessage            NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeMail               NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePrint              NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeCopyToPasteboard   NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeAssignToContact    NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeSaveToCameraRoll   NS_AVAILABLE_IOS(6_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeAddToReadingList   NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToFlickr       NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToVimeo        NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToTencentWeibo NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeAirDrop            NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeOpenInIBooks 

如果我们不想展示AirDrop功能，我们把UIActivityTypeAirDrop添加到excludedActivityTypes里面：

activityViewController.excludedActivityTypes = @[UIActivityTypeAirDrop];

自定义UIActivity对象

UIActivity类中的方法说明:

//分享类型，我们自定义UIActivity有多种类型，如分享微信、朋友圈、微博、QQ等，所以要指定类型，方便我们在performActivity事件中判断用户行为
- (nullable UIActivityType)activityType;
//显示的title
- (nullable NSString *)activityTitle;
//显示的图标
- (nullable UIImage *)activityImage;
//用户的行为事件捕获，可以根据activityTitle判断用户行为
- (void)performActivity;
//在用户选择展示在UIActivityViewController中的自定义服务的图标之后，调用自定义服务处理方法之前的准备工作，都需要在这个方法中指定，比如可以根据数据展示一个界面来获取用户指定的额外数据信息
- (void)prepareWithActivityItems:(NSArray *)activityItems;
//指定可以处理的数据类型，如果可以处理则返回YES
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems;
//UIActivityViewController中的服务分为了俩种，UIActivityCategoryAction和UIActivityCategoryShare,UIActivityCategoryAction表示在最下面一栏的操作型服务,比如Copy、Print;UIActivityCategoryShare表示在中间一栏的分享型服务，比如一些社交软件
 + (UIActivityCategory)activityCategory NS_AVAILABLE_IOS(7_0);

代码实现：

自定义UIActivity对象代码：

NSString * const ActivityServiceWeixin = @"weixin";
NSString * const ActivityServiceWeixinFriends = @"weixin_friends";
@interface HBShareBaseActivity : UIActivity
@property (nonatomic) NSString *title;
@property (nonatomic) NSString *type;
@property (nonatomic) NSString *urlString;
@property (nonatomic) NSString *shareDescription;
@property (nonatomic) NSString *shareTitle;
@property (nonatomic) UIImage *image;
- (instancetype)initWithTitle:(NSString *)title type:(NSString *)type;
@end

@implementation HBShareBaseActivity
- (instancetype)initWithTitle:(NSString *)title type:(NSString *)type{
    if (self = [super init]) {
        self.title = title;
        self.type = type;
    }
    return self;
}
- (NSString *)activityTitle{
    return self.title;
}
- (NSString *)activityType{
    return self.type;
}
- (UIImage *)activityImage{
    NSString *weixinImageString = @"ic_share_wechat";
    NSString *friendsImageString = @"ic_share_circle";
    NSString *imageName = [self.type isEqualToString:ActivityServiceWeixin] ?      weixinImageString: friendsImageString;
    NSData *imageData = [NSData dataWithBase64EncodedString:imageName];
    return [UIImage imageWithData:imageData scale:2.0];
}
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems{
    return YES;
}
- (void)prepareWithActivityItems:(NSArray *)activityItems
{
}
- (void)performActivity{    
  if ([self.type isEqualToString:ActivityServiceWeixin]) {
        NSLog(@"在这里可以实现微信分享代码");
    }else{
        NSLog(@"在这里可以实现朋友圈分享代码");
    }
}
@end

创建ShareTool类，继承自NSObject，使用自定义的HBShareBaseActivity类，代码实现如下：

@interface ShareTool : NSObject
- (void)shareWithTitle:(NSString *)title description:(NSString *)description url:(NSString *)url image:(UIImage *)image completionHandler:(UIActivityViewControllerCompletionHandler)completionHandler;
@end
@interface ShareTool()
@property (nonatomic, copy) UIActivityViewControllerCompletionHandler completionHandler;
@end
@implementation ShareTool
- (void)shareWithTitle:(NSString *)title description:(NSString *)description url:(NSString *)url image:(UIImage *)image completionHandler:(UIActivityViewControllerCompletionHandler)completionHandler
{
    NSMutableArray *items = [[NSMutableArray alloc] init];
    [items addObject:title?:@""];
    if (image) {
        [items addObject:image];
    }
    if (url) {
        [items addObject:url];
    }
    
    NSMutableArray *activities = [[NSMutableArray alloc] init];
    HBShareBaseActivity *weixinActivity = [[HBShareBaseActivity alloc] initWithTitle:@"微信" type:ActivityServiceWeixin];
    HBShareBaseActivity *weixinFriendsActivity = [[HBShareBaseActivity alloc] initWithTitle:@"朋友圈" type:ActivityServiceWeixinFriends];
    [@[weixinActivity, weixinFriendsActivity] enumerateObjectsUsingBlock:^(HBShareBaseActivity *activity, NSUInteger idx, BOOL *stop) {
        activity.urlString = url;
        activity.shareDescription = description;
        activity.shareTitle = title;
        activity.image = image;
    }];
    [activities addObjectsFromArray:@[weixinActivity, weixinFriendsActivity]];
    
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:activities];
    NSMutableArray *excludedActivityTypes =  [NSMutableArray arrayWithArray:@[UIActivityTypeAirDrop, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeMail, UIActivityTypePostToTencentWeibo, UIActivityTypeSaveToCameraRoll, UIActivityTypeMessage, UIActivityTypePostToTwitter]];

    activityViewController.excludedActivityTypes = excludedActivityTypes;
    AppDelegate *tempAppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    [tempAppDelegate.window.rootViewController presentViewController:activityViewController animated:YES completion:nil];

    activityViewController.completionHandler = ^(NSString *activityType, BOOL complted){
        if (completionHandler) {
            completionHandler(activityType, complted);
            self.completionHandler = nil;
        }
    };
}

在ViewController中调用代码如下：

 [[[ShareTool alloc] init] shareWithTitle:@"分享的title" description:@"描述信息" url:@"http://www.baidu.com" image:[UIImage imageNamed:@"1"] completionHandler:^(UIActivityType  _Nullable activityType, BOOL completed) {
       NSLog(@"%@  %d", activityType, completed);
   }];

补充：

在UIActivityViewController中给用户展示的服务的图标activityImage。关于这里的图标，有非常严格的限制：

• 首先是图标的背景色，这里推荐最好的完全透明的背景色;
  官方文档中是这么解释的:"The alpha channel of the image is used as a mask to generate the final image that is presented to the user. Any color data in the image itself is ignored. Opaque pixels have a gradient applied to them and this gradient is then laid on top of a standard background. Thus, a completely opaque image would yield a gradient filled rectangle",意思大概是，在这里颜色数据会被忽略，而透明图层会被当做mask(蒙版图层)，不透明的图片会显示成渐进色填充。

• 其次是图标的尺寸，在不同的设备需要不同的尺寸，因此需要准备一套图标。

  
  
  
  

  因此上面代码中图片地址：

NSString *weixinImageString = @"ic_share_wechat";
NSString *friendsImageString = @"ic_share_circle";
