Answer 1

试试这个库，它将帮助您下载图像并显示在imageview中。

Answer 2

The same code working for me fine !!!!!!

Please check the Internet Connection.

Please check the NSData *data size

Please check the UIImageView Size

Please check it hided by some other controls

Please check it added properly to your View

Please check its Content View

@property(nonatomic,retain) IBOutlet UIImageView *imageview;

NSURL *url = [NSURL URLWithString:@"http://www.scri8e.com/effects/FL0WERZ/PNG/ir09.png"];
NSData *data = [[NSData alloc]initWithContentsOfURL:url ];
UIImage *img = [[UIImage alloc]initWithData:data ];
self.imageview.image=img;

Answer 3

如果直接在xib中拍摄了imageview，则不只是在连接检查器中检查连接。

Answer 4

使用EgoImageView而不是ImageView。

Answer 5

NSString *mainimg=[NSString stringWithFormat:@"%@",[[xmlDataDictionary valueForKeyPath:@"eg.main.img1"]objectAtIndex:indexPath.row]];
NSURL *url = [NSURL URLWithString:mainimg];
NSData *image = [[NSData alloc] initWithContentsOfURL:url];
cell.img.image=[UIImage imageWithData:image];

Try this for parsed url..

So simple..

Answer 6

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSString *url_Img1 = @"http://www.scri8e.com/effects/FL0WERZ/PNG";
    NSString *url_Img2 = @"ir09.png";

    NSString *url_Img_FULL = [url_Img1 stringByAppendingPathComponent:url_Img2];

    NSLog(@"Show url_Img_FULL: %@",url_Img_FULL);
    _view_Image.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url_Img_FULL]]];

}
