Ios Iterate IBOutletCollection TextView

Question

我想迭代並顯示我的文本視圖集合上的數組。

@property (strong, nonatomic) IBOutletCollection(UITextView) NSArray *myTextViewCollection;

但在UI，只在我的數組的最後一個元素是可用的。

我用迭代：

for (UITextView *textView in myTextViewCollection) { 
     for (int i = 0; i < feeds.count; i++) { 
      textView.text = [[feeds objectAtIndex:i] objectForKey:@"title"]; 
      textView.editable = false; 
     } 
    } 

feeds是NSMutableArray的contening NSMutableDictionnary對象的列表。

一個想法？

Answer 1

應該是這樣的：

for (int i = 0; i < myTextViewCollection.count; i++) { 
    UITextView * textView = myTextViewCollection[i]; 
    textView.text = [[feeds objectAtIndex:i] objectForKey:@"title"]; 
    textView.editable = false; 
} 

Answer 2

試試這個：

int i = 0; 
for (UITextView *textView in myTextViewCollection) { 
    textView.text = [[feeds objectAtIndex:i++] objectForKey:@"title"]; 
    textView.editable = false; 
} 

Answer 3

您的代碼

for (UITextView *textView in myTextViewCollection) { 
    for (int i = 0; i < feeds.count; i++) { 
     textView.text = [[feeds objectAtIndex:i] objectForKey:@"title"]; 
     textView.editable = false; 
    } 
} 

相當於

for (UITextView *textView in myTextViewCollection) { 
    textView.text = [[feeds objectAtIndex:feeds.count - 1] objectForKey:@"title"]; 
    textView.editable = false; 
} 

這就是爲什麼只顯示最後一個元素數組的原因。

你應該改變代碼爲類似

int i = 0; 
for (UITextView *textView in myTextViewCollection) { 
    textView.text = feeds[i++][@"title"]; 
    textView.editable = false; 
}
