ios android 截屏分享,iOS 系统自带截屏分享-优快云博客

这篇博客介绍了如何在iOS系统中实现截屏分享功能，并通过代码隐藏不需要显示的区域。利用KJTools的kj_shareWithHideBlock方法可以自定义隐藏截图上的特定内容，然后通过kj_share方法调用原生分享接口，排除特定的分享类型，如邮件和信息。代码适用于iOS 9.0及更高版本。

分享一篇iOS系统自带截屏分享

使用方案

UIImage *image = [KJTools kj_shareWithHideBlock:^bool{

/// 隐藏不需要截图的区域

return YES;

}];

[KJTools kj_share:@[UIImagePNGRepresentation(image)] ViewController:weakself Success:^(BOOL success) {

/// 分享完成处理

}];

简单粗暴，贴上代码

/// 分享截图隐藏多余部分

+ (UIImage*)kj_shareWithHideBlock:(bool(^)(void))block{

if (block && block()) return [UIImage kj_captureScreenWindow];

return nil;

}

/// 原生分享

+ (void)kj_share:(NSArray*)items ViewController:(UIViewController*)vc Success:(void (^)(BOOL success))block{

if (items.count == 0) return;

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:nil];

if (@available(iOS 11.0, *)) {

activityVC.excludedActivityTypes = @[UIActivityTypeMessage, UIActivityTypeMail, UIActivityTypeOpenInIBooks, UIActivityTypeMarkupAsPDF];

}else if (@available(iOS 9.0, *)){

activityVC.excludedActivityTypes = @[UIActivityTypeMessage, UIActivityTypeMail, UIActivityTypeOpenInIBooks];

}else{

activityVC.excludedActivityTypes = @[UIActivityTypeMessage, UIActivityTypeMail];

}

UIActivityViewControllerCompletionWithItemsHandler itemsBlock = ^(UIActivityType _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {

if (block) block(completed);

};

activityVC.completionWithItemsHandler = itemsBlock;

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {

activityVC.popoverPresentationController.sourceView = vc.view;

activityVC.popoverPresentationController.sourceRect = CGRectMake([UIScreen mainScreen].bounds.size.width/2, [UIScreen mainScreen].bounds.size.height, 0, 0);

[vc presentViewController:activityVC animated:YES completion:nil];

}else{

[vc presentViewController:activityVC animated:YES completion:nil];

}
