で画像を表示するためのUITableViewを使用するために、私は（Webサービスから来ている）の画像を表示する画面で出力画像の下のように表示されていることを形式は、： -iphone + UIScrollViewのか、行列形式
私が実装したロジックは、uiscrollviewでイメージを追加したことです。以下のロジックと ： -
for (int j=0;j<9;j++) {
for (int i=0; i<[mainRestaurantArray count];i++) {
if ([[[mainRestaurantArray objectAtIndex:i] valueForKey:@"Image"] isKindOfClass:[UIImage class]]) {
[CombineArray addObject:[mainRestaurantArray objectAtIndex:i]];
//NSLog(@"cnt=>%d array==>%@",cnt,[CombineArray objectAtIndex:cnt]);
UIButton* btn = [[UIButton alloc]init];
btn.tag = cnt;
btn.frame = CGRectMake(15+(cnt%5)*60, 15+(cnt/5)*60,Width,Height);
btn.backgroundColor = [UIColor greenColor];
[btn setBackgroundImage:[[CombineArray objectAtIndex:cnt] valueForKey:@"Image"] forState:UIControlStateNormal];
[btn addTarget:self action:@selector(Buttonclick:) forControlEvents:UIControlEventTouchUpInside];
[ScrlPhotos addSubview:btn];
[btn release];
cnt++;
}
}
[mainRestaurantArray release];
counter++;
[self urlcalled];//The function which calls the webservice
}
//}
ScrlPhotos.contentSize = CGSizeMake(320, ([CombineArray count]/5.0)*60+25);
Webサービスを行う機能は以下の通りです： -
-(void)urlcalled{
@try
{
if (rangeDistance == nil) {
rangeDistance [email protected]"100";
}
urlstring[0]=[NSString stringWithFormat:@"http://www.google.com/maps?q=Gym&sll=%@,%@&radius=200000&output=json",AppDel.Latitude,AppDel.Longitude];
urlstring[1]=[NSString stringWithFormat:@"http://www.google.com/maps?q=resort&sll=%@,%@&radius=200000&output=json",AppDel.Latitude,AppDel.Longitude];

NSLog(@"conte==>%d urlstring[counter]==>%@",counter,urlstring[counter]);

if(range.location == NSNotFound){
NSLog(@"Not found");
[dic setValue:@"" forKey:@"Image"];

NSString *strImage1 = [arrayImage objectAtIndex:1];
NSArray *arrayImage1 = [strImage1 componentsSeparatedByString:@",photoType:"];
NSString *strfindImage = [[arrayImage1 objectAtIndex:0] stringByReplacingOccurrencesOfString:@"\"" withString:@""];
myImage = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:strfindImage]]];
[dic setValue:myImage forKey:@"Image"];
}
[mainRestaurantArray addObject:dic];
if (i==20) {
break;
}
}
}
@catch (NSException * e)
{
NSLog(@"NSException==>%@",e);
}
}
しかし、私が直面しています問題は、画像が10回でループを完了した後に表示されています。 私は、webserviceから来るように画像を平行して表示したいので、時間が少なくて済むようにしてください。
私を助けてください。
