Acquiring/obtaining image from mysql database via php code for iphone app
I'm uploading images to mySQL DB as a MediumBLOB since it allows me to upload images of upto sizes of 16 MB. In my iPhone app code, I'm just making a call to the PHP function which has the SQL query which says "select * from skin_table";
I need to apply skins to my app, so each of these skins have a name, like football, soccer, cricket, tennis, hockey, etc...
The names of each of the skins are being loaded through a picker view.
But, I need to fetch the images as well.
In short, I just want to download images from the server on to my iPhone app.
I'm 开发者_Python百科using NSXMLParser delegate methods:
In declaration file ".h":
UIImage *currentSkin;
NSData *currentSkinData;
In the implementation file ".m":
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
attributes: (NSDictionary *)attributeDict
{
dictitem = [[NSMutableDictionary alloc] init];
currentTitle = [[NSMutableString alloc] init];
currentId = [[NSMutableString alloc] init];
currentSkin = [[UIImage alloc]init];
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if ([currentElement isEqualToString:@"id"]) {
[currentId appendString:string];
}
else if ([currentElement isEqualToString:@"long_name"]) {
[currentTitle appendString:string];
}
else if ([currentElement isEqualToString:@"skin_image"])
{
//currentSkin = [[UIImage alloc]initWithContentsOfFile:string];
//currentSkinData = UIImagePNGRepresentation(currentSkin);
//NSUInteger len = [currentSkinData length];
//Byte *byteData = (Byte*)malloc(len);
//memcpy(byteData, [currentSkinData bytes], len);
/* What goes here?? */
}
I'm going to try doing this myself and will put up the code by editing this same post if I get through. I needed to get this done as soon as possible therefore I thought of asking some help, as I'd been sitting with this for the past two days that includes today.
UIImage *image1 = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url]]];
This way you might be able to get the image.
