我現在在GalleryScrollView.m中只有1個錯誤。我想我宣佈畫廊按鈕錯了。錯誤實例方法-initwithFrame：imageName：找不到imgname Objective-C
的錯誤是：
Instance Method -initwithFrame:imageName:imgname not found
這一行：
GalleryButton *btnAttachment = [[GalleryButton alloc] initWithFrame:CGRectMake(startX, startY, width, height) imageName:imgName];
我已經試過- (void) removeAttachment:(GalleryButton *)button imageName;
，但似乎並沒有工作。以下是我的代碼。
任何意見或回答非常感謝。
謝謝。

現在它給了我一個警告GalleryButton可能不會響應iniWithFrame：imageNamed？任何原因爲什麼後我在我的頭文件中聲明 - （id）initWithFrame：（CGRect）frame imageName：（NSString *）imageName; –
你是否聲明你是一個GalleryButton或一個UIButton嗎？如果它是一個GalleryButton你不應該有這個警告。你不會忽略這個警告，因爲你的方法可能不會被調用 – tiguero
