界面生成器未顯示我的IBOutlets

Question

我找到了此鏈接 ， 該鏈接提供了從查找程序打開我的項目的解決方案。 沒運氣。

我知道我的代碼應該可以工作，因為我有一堆UITextfields，其中大約一半可以工作，而另一半卻沒有幾乎相同的代碼。 我懷疑我只是擁有太多的IBOutlets和Interface Builder，因為我有太多，所以不再顯示給我。 （有13個標簽和12個文本字段已經完全起作用，正在嘗試添加12個以上的文本字段）。

Interface Builder是否具有某種＃-of-outlet限制，這是XCode錯誤還是在Interface Builder中存在設置，我可能不小心更改了該設置以導致此行為？

編輯：我的.h文件-我為它的可怕程度表示歉意。

您僅將IBOutlet放在某些UITextField屬性聲明的前面。 在標題中，確保將IBOutlet放在所有標題的前面，如下所示：

// Attempts //
// 333
@property (strong, nonatomic) IBOutlet UITextField *field333attempt1a1, *field333attempt1a2, *field333attempt1a3, *field333attempt1b1, *field333attempt1b2, *field333attempt1b3;
@property (strong, nonatomic) IBOutlet UITextField *field333attempt2a1, *field333attempt2a2, *field333attempt2a3, *field333attempt2b1, *field333attempt2b2, *field333attempt2b3;
// 363
@property (strong, nonatomic) IBOutlet UITextField *field363attempt1a1, *field363attempt1a2, *field363attempt1a3, *field363attempt1b1, *field363attempt1b2, *field363attempt1b3;
@property (strong, nonatomic) IBOutlet UITextField *field363attempt2a1, *field363attempt2a2, *field363attempt2a3, *field363attempt2b1, *field363attempt2b2, *field363attempt2b3;
// Cycle
@property (strong, nonatomic) IBOutlet UITextField *fieldCycleattempt1a1,  *fieldCycleattempt1a2, *fieldCycleattempt1a3, *fieldCycleattempt1b1, *fieldCycleattempt1b2, *fieldCycleattempt1b3;
@property (strong, nonatomic) IBOutlet UITextField *fieldCycleattempt2a1, *fieldCycleattempt2a2, *fieldCycleattempt2a3, *fieldCycleattempt2b1, *fieldCycleattempt2b2, *fieldCycleattempt2b3;

您的代碼：

@property (strong, nonatomic) IBOutlet UITextField *field333attempt1a1, *field333attempt1a2, *field333attempt1a3, *field333attempt1b1, *field333attempt1b2, *field333attempt1b3;
@property (strong, nonatomic) UITextField *field333attempt2a1, *field333attempt2a2, *field333attempt2a3, *field333attempt2b1, *field333attempt2b2, *field333attempt2b3;

// 363
@property (strong, nonatomic) IBOutlet UITextField *field363attempt1a1, *field363attempt1a2, *field363attempt1a3, *field363attempt1b1, *field363attempt1b2, *field363attempt1b3;
@property (strong, nonatomic) UITextField *field363attempt2a1, *field363attempt2a2, *field363attempt2a3, *field363attempt2b1, *field363attempt2b2, *field363attempt2b3;

// Cycle
@property (strong, nonatomic) IBOutlet UITextField *fieldCycleattempt1a1,  *fieldCycleattempt1a2, *fieldCycleattempt1a3, *fieldCycleattempt1b1, *fieldCycleattempt1b2, *fieldCycleattempt1b3;
@property (strong, nonatomic) UITextField *fieldCycleattempt2a1, *fieldCycleattempt2a2, *fieldCycleattempt2a3, *fieldCycleattempt2b1, *fieldCycleattempt2b2, *fieldCycleattempt2b3;

在第二，第四和第六行代碼中存在錯誤。 您沒有將UITextField定義為IBOutlet。

將IBOutlet添加到UITextFields，它將可以正常工作。

新代碼：

@property (strong, nonatomic) IBOutlet UITextField *field333attempt1a1, *field333attempt1a2, *field333attempt1a3, *field333attempt1b1, *field333attempt1b2, *field333attempt1b3;
@property (strong, nonatomic) IBOutlet UITextField *field333attempt1a1, *field333attempt1a2, *field333attempt1a3, *field333attempt1b1, *field333attempt1b2, *field333attempt1b3;

//363
@property (strong, nonatomic) IBOutlet UITextField *field363attempt1a1, *field363attempt1a2, *field363attempt1a3, *field363attempt1b1, *field363attempt1b2, *field363attempt1b3;
@property (strong, nonatomic) IBOutlet UITextField *field363attempt2a1, *field363attempt2a2, *field363attempt2a3, *field363attempt2b1, *field363attempt2b2, *field363attempt2b3;

// Cycle
@property (strong, nonatomic) IBOutlet UITextField *fieldCycleattempt1a1,  *fieldCycleattempt1a2, *fieldCycleattempt1a3, *fieldCycleattempt1b1, *fieldCycleattempt1b2, *fieldCycleattempt1b3;
@property (strong, nonatomic) IBOutlet UITextField *fieldCycleattempt2a1, *fieldCycleattempt2a2, *fieldCycleattempt2a3, *fieldCycleattempt2b1, *fieldCycleattempt2b2, *fieldCycleattempt2b3;
