画像を読み込んで表示し、テーブルビュー セルに表示しようとしています。画像は Google からのリンクです。簡単な読み込みに使用しようとしましdispatch_asyncたが、すべての画像が読み込まれません。
私のコードの一部を次に示します。
-(void) buildCellView: (NSArray *) data andIndex: (NSInteger) index{
NSDictionary *comment = [data objectAtIndex:index];
cell.backgroundColor = [BaseView colorWithHexString:@"f3f3f3"];
commentsView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height)];
commentUsersImg = [[UIImageView alloc] initWithFrame:CGRectMake(15, 8, 28, 28)];
if ([comment valueForKeyPath:@"image_url"] !=nil) {
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^(void){
NSURL * url = [[NSURL alloc] initWithString:[comment valueForKeyPath:@"image_url"]];
NSData * imageData = [[NSData alloc] initWithContentsOfURL:url] ;
dispatch_async(dispatch_get_main_queue(), ^(void){
// commentUsersImg.image = [UIImage imageWithData:imageData];
[[self commentUsersImg] setImage:[UIImage imageWithData:imageData]];
});
});
}
commentUsersImg.layer.cornerRadius = 14;
commentUsersImg.clipsToBounds = YES;
[commentsView addSubview:commentUsersImg];
これは私が得ているものです:
URLを配列に保存します。これは、配列の配列の一部です。
