我正在使用 JSON 解析，我将数据放入名为 JSON Array 的数组中。在控制台中它看起来像
JSON Array=(
{
"created_by" = 42;
"created_on" = "2012-02-29 11:23:37";
"file_description" = "";
"file_is_downloadable" = 0;
"file_is_forSale" = 0;
"file_is_product_image" = 1;
"file_meta" = "";
"file_mimetype" = "image/jpeg";
"file_params" = "";
"file_title" = "hand shovel";
"file_type" = product;
"file_url" = "images/stories/virtuemart/product/cca3cd5db813ee6badf6a3598832f2fc.jpg";
"file_url_thumb" = "images/stories/virtuemart/product/resized/cca3cd5db813ee6badf6a3598832f2fc_90x90.jpg";
"locked_by" = 0;
"locked_on" = "0000-00-00 00:00:00";
"modified_by" = 42;
"modified_on" = "2012-02-29 11:23:37";
ordering = 0;
"product_name" = "Hand Shovel";
published = 0;
shared = 0;
"virtuemart_category_id" = 1;
"virtuemart_media_id" = 13;
"virtuemart_product_id" = 1;
"virtuemart_vendor_id" = 1;
},
{
"created_by" = 42;
"created_on" = "2012-02-29 11:35:09";
"file_description" = "";
"file_is_downloadable" = 0;
"file_is_forSale" = 0;
"file_is_product_image" = 1;
"file_meta" = "";
"file_mimetype" = "image/jpeg";
"file_params" = "";
"file_title" = "our ladder";
"file_type" = product;
"file_url" = "images/stories/virtuemart/product/8cb8d644ef299639b7eab25829d13dbc.jpg";
"file_url_thumb" = "images/stories/virtuemart/product/resized/8cb8d644ef299639b7eab25829d13dbc_90x90.jpg";
"locked_by" = 0;
"locked_on" = "0000-00-00 00:00:00";
"modified_by" = 42;
"modified_on" = "2012-02-29 11:35:09";
ordering = 0;
"product_name" = Ladder;
published = 0;
shared = 0;
"virtuemart_category_id" = 3;
"virtuemart_media_id" = 8;
"virtuemart_product_id" = 2;
"virtuemart_vendor_id" = 1;
},
现在我需要选择“file_url_thumb”，它实际上是单独数组中的图像。 请让我知道我该怎么做？
最佳答案
//Your array has two dictionary ..
for(NSMutableDictionary *dict in JSON_Array){
NSString *urlString = [dict objectForKey:@"file_url_thumb"];
if(urlString){
NSURL *url = [NSURL urlWithString:urlString];
NSData* imageData = [[NSData alloc] initWithContentsOfURL:url]];
UIImage* image = [[UIImage alloc] initWithData:imageData];
//show your image on imageview
}
}
希望这对您有帮助
