靜態TableView崩潰時，我添加圖像

Question

所以我正在爲我的一個朋友的東西，我有一些問題。我爲每個武器類別提供了一系列文本和圖像。應用程序運行良好，但後來我添加了圖像，現在它只是崩潰。看看，如果你有什麼想法，請讓我知道。謝謝！

Answer 1

我認爲這個問題是缺乏支架正確界定圍繞你的if/else語句範圍。見cellForRowAtIndexPath:

int row = [indexPath row]; 

if (indexPath.section==0) 
    cell.TitleLabel.text = _assault[row]; 
    cell.myImageView.image = [UIImage imageNamed:_assault1[row]]; 

else ... 

這這行代碼運行的每個cellForRowAtIndexPath被調用的時候，不管是哪個部分你indexPath是：

cell.myImageView.image = [UIImage imageNamed:_assault1[row]]; 

添加花括號你的if/else條件和你」請確保您所參考的那一行位於正確的部分。

Answer 2

此崩潰的原因：

[__NSArrayI objectAtIndex:]: index 3 beyond bounds [0 .. 2] 

是您正在試圖從一些陣列的第四個對象（位於索引3的對象），但這個數組只有三個對象。我建議使用斷點來找出發生的地方和原因。

我希望它有幫助。
