LPLinkView 是官方iOS13開始提供的一種鏈接預(yù)覽的超級方便的view實(shí)現(xiàn)。

LPLinkView presents a link based on its available metadata. Use it to show a link’s title and icon, associated images, inline audio, video playback, and maps in a familiar and consistent style.

意思大概是 LPLinkView根據(jù)其可用的元數(shù)據(jù)顯示一個鏈接。使用它可以以熟悉且一致的樣式顯示鏈接的標(biāo)題和圖標(biāo)，關(guān)聯(lián)的圖像，嵌入式音頻，視頻播放和地圖。

其簡單的使用方法如下：

#import "ViewController.h"
#import <LinkPresentation/LPMetadataProvider.h>
#import <LinkPresentation/LPLinkView.h>
@interface ViewController ()

@property (nonatomic ,strong) LPLinkMetadata *linkMetadata;
@property (nonatomic ,strong) LPLinkView *linkView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    LPMetadataProvider *pv = [LPMetadataProvider new];
    NSString *url = @"https://www.baidu.com";
    __weak typeof(self) weakSelf = self;
    [pv startFetchingMetadataForURL:[NSURL URLWithString:url] completionHandler:^(LPLinkMetadata * _Nullable metadata, NSError * _Nullable error) {
        if (!error) {
            weakSelf.linkMetadata = metadata;
        }
    }];
}

- (void)setLinkMetadata:(LPLinkMetadata *)linkMetadata {
    _linkMetadata = linkMetadata;
    dispatch_async(dispatch_get_main_queue(), ^{
        self.linkView = [[LPLinkView alloc] initWithMetadata:linkMetadata];
        self.linkView.frame = CGRectMake(10, 80, 300, 600);
        [self.view addSubview:self.linkView];
        [self.linkView sizeToFit];
    });
}

運(yùn)行結(jié)果如圖
