下面我来介绍一下利用原生UIActivityViewController快速实现QQ和微信分享
- 创建要分享的数据内容，加在一个数组 ActivityItems里
NSString *shareText = @"我是title";
//图片应是加载完成后的image或本地的image，否则可能会出错
UIImage *shareImage = [UIImage imageNamed:@"shareImage"];
NSURL *shareUrl = [NSURL URLWithString:@"//www.greatytc.com/u/15d37d620d5b"];
NSArray *activityItemsArray = @[shareText,shareImage,shareUrl];
- 创建分享视图控制器，初始化UIActivityViewController
//第一个参数 分享的内容
//第二个参数 是一个UIActivity对象的数组，代表了应用程序支持的自定义服务。这个参数可以是nil
- (instancetype)initWithActivityItems:(NSArray *)activityItems applicationActivities:(nullable NSArray<__kindof UIActivity *> *)applicationActivities
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems: activityItemsArray applicationActivities:nil];
activityVC.modalInPopover = YES;
//去除特定的分享功能 不需要展现的Activity类型
activityVC.excludedActivityTypes = @[
UIActivityTypePostToFacebook,
UIActivityTypePostToTwitter,
UIActivityTypePostToWeibo,
UIActivityTypeMessage,
UIActivityTypeMail,
UIActivityTypePrint,
UIActivityTypeCopyToPasteboard,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo,
UIActivityTypeAirDrop,
UIActivityTypeOpenInIBooks
];
- 根据系统版本，设置点击回调
if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) { // ios8.0 之后用此方法回调
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 之前用此方法回调
UIActivityViewControllerCompletionHandler handlerBlock = ^(UIActivityType __nullable activityType, BOOL completed){
NSLog(@"activityType == %@",activityType);
if (completed == YES) {
NSLog(@"completed");
} else {
NSLog(@"cancel");
}
};
activityVC.completionHandler = handlerBlock;
}
- 根据设备类型使用相应方法展示
- iPad上，必须通过popover 参考
- iPhone和iPodtouch上，必须以模态的方式展现
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {//iPad
UIBarButtonItem *shareBarButtonItem = self.navigationItem.leftBarButtonItem;
UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
[popup presentPopoverFromBarButtonItem:shareBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
} else {
[self presentViewController:activityViewController animated:YES completion:nil];
}

至此，简单的分享功能就实现完成了，不需要导入微信的SDK。是不是很简单。
自定义UIActivity，主要就是重写父类的方法，以后用到的话再详细介绍。
