导读:我想使用URL和NSString在UI ImageView上显示图像.我无法显示图像. 我的代码是: UIImageView *view_Image = [[UIImageView alloc]initWithFrame:CGRectMake(view_Image_Pos_X,view_Image_Pos_Y,179,245)];view_Image.backgroundColor = [UIColor greenColor]
我想使用URL和NSString在UI
ImageView上显示图像.我无法显示图像.
我的代码是: UIImageView *view_Image = [[UIImageView alloc]initWithFrame:CGRectMake(view_Image_Pos_X,view_Image_Pos_Y,179,245)]; view_Image.backgroundColor = [UIColor greenColor]; view_Image.tag = img; view_Image.userInteractionEnabled=YES; view_Image.autoresizesSubviews = YES; view_Image.alpha = 0.93; [self.view addSubview:view_Image]; 在这里我正在尝试: if (img == 0) { NSString *url_Img1 = @"http://opensum.in/app_test_f1/;"; NSString *url_Img2 = @"45djx96.jpg"; NSString *url_Img_FULL = [NSString stringWithFormat:@"%@%@",url_Img1,url_Img2]; NSLog(@"Show url_Img_FULL: %@",url_Img_FULL); NSURL *url_img = [NSURL URLWithString:url_Img_FULL]; NSLog(@"Show: url_img %@",url_img); // Here below line working perfectly and image is showing view_Image.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://opensum.in/app_test_f1/45djx96.jpg"]]]; // working code 但我不想要这个我想连续两个网址制作一个网址(即; url_Img_FULL),然后传递到如下图像: UIImage * image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url_Img_FULL]]]; //不工作 我想从“url_Img_FULL”(即:两个网址的组合)图像将显示. 解决方法NSString *url_Img1 = @"http://opensum.in/app_test_f1"; NSString *url_Img2 = @"45djx96.jpg"; 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]]]; 试试这个.
