コンポーネントが 1 つしかない UIImagePicker に画像を実装しようとしています。uimageview と uilabel を追加します。キャッチは、最初の行には画像がなく、3行目には正しいと信じていることです。私の問題は、各行の画像が異なることです。これを解決するために、それらを画像の配列に入れてから、渡された行に基づいて画像を表示します。でも; それは私にとってはうまくいかず、同じ画像が何度も表示されるようです。誰でも理由を教えてもらえますか? 前もって感謝します!
imageNames= [[NSArray alloc] initWithObjects:@"9_stars.png", @"8_stars.png",@"7_stars.png",@"6_stars.png",@"5_stars.png",@"4_stars.png", nil];
