更新1中:
這裏是cellForItemAtIndexPath
YTPlayerView一個UICollectionView動態小區
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
MBDynamicCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:
indexPath];
video= videoData[indexPath.row];
if(!cell) {
cell = [MBDynamicCollectionViewCell new];
}
[cell.videoPlayer loadWithVideoId:video.videoID];
cell.label1.text = [NSString stringWithFormat:@"%@",video.videoTitle];
return cell;
}
代碼,這裏是我如何發送請求到服務器
NSURL *url=[ NSURL URLWithString:@"https://www.googleapis.com/youtube/v3/search?key=AIzaSyClU73k2yYl7gufFDxHU7uhGSCuM78f7Aw&channelId=UCW9CKYMhpJM-B1B0PGBB9Ew&part=snippet,id&order=date&maxResults=20"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSOperationQueue *queue= [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response,NSData *data,NSError *error){
if(error){
NSLog(@"error:%@", error.localizedDescription);
}
else{
NSError *error;
NSMutableDictionary *allVideos= [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
// NSString *string=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
// NSLog(@"%@",string);
for(NSDictionary *dictionary in allVideos[@"items"]){
NSDictionary *videoID=dictionary[@"id"];
// NSLog(@"video id is %@", videoID[@"videoId"]);
NSDictionary *snippet= dictionary[@"snippet"];
//NSLog(@"video title is %@", snippet[@"title"]);
NSDictionary *thumbnails= dictionary[@"snippet"][@"thumbnails"][@"default"];
//NSLog(@"video image url is %@",thumbnails[@"url"]);
video=[[MBVideoClass alloc] initWithID:videoID[@"videoId"] withTitle:snippet[@"title"] withImg:thumbnails[@"url"] delegate:self];
[videoData addObject:video];
}
videoData= [NSMutableArray arrayWithArray:[videoData filteredArrayUsingPredicate:pred]];
[self.collectionView reloadData];
}
}];
一部開拓創新的問題
我有一個dded YTPlayerView
裏面有一個UICollectionView
動態單元格。
我的應用程序在創建新的Web視圖時出現「訪問錯誤」時發生錯誤
當我嘗試在collectionView:cellForItemAtIndexPath:
內部初始化webView時出現此問題。
有什麼想法?
