iOS 多线程开发以及网络图片加载

NSDictionary*group=[[NSDictionaryalloc]initWithObjectsAndKeys:indexPath,@"indexpath",cell,@"cell",nil];

[NSThreaddetachNewThreadSelector:@selector(loadLabelTableView:)toTarget:selfwithObject:group];

-(void)loadLabelTableView:(NSDictionary*)group

{

UILabel*label=[[UILabelalloc]initWithFrame:CGRectMake(50,10,200,30)];

NSString*codeCharacter=[[m_listDataobjectAtIndex:[[groupobjectForKey:@"indexpath"]row]]substringWithRange:NSMakeRange(0,2)];

NSString*codeNumber=[[m_listDataobjectAtIndex:[[groupobjectForKey:@"indexpath"]row]]substringWithRange:NSMakeRange(3,6)];

NSString*codeName=[[m_listDataobjectAtIndex:[[groupobjectForKey:@"indexpath"]row]]substringWithRange:NSMakeRange(10,4)];

NSString*stockList=[NSStringstringWithFormat:@"%@%@\t%@",codeCharacter,codeNumber,codeName];

label.text=stockList;

[[groupobjectForKey:@"cell"]addSubview:label];

}

网络图片加载方式：

-(void)loadImageCollectionView:(NSDictionary*)group

{

UIImageView*imageView=[[UIImageViewalloc]initWithFrame:CGRectMake(5,2,70,100)];

NSData*data=[NSDatadataWithContentsOfURL:[NSURLURLWithString:[[[listDataobjectAtIndex:[[groupobjectForKey:@"indexpath"]row]]objectForKey:@"images"]objectForKey:@"small"]]];

UIImage*img=[UIImageimageWithData:data];

imageView.image=img;

[[groupobjectForKey:@"cell"]addSubview:imageView];

}
