UITableview與文本字段到陣列

我不知道如果我正在接近這個正確的方式，所以我需要一些幫助。我有一個5行的表格供輸入數據。用戶輸入所有數據後，導航欄上會有一個按鈕將數據添加到陣列。我想設置另一個視圖控制器來顯示用戶輸入的所有數據。我希望這是有道理的。這是迄今爲止我所擁有的。UITableview與文本字段到陣列

有沒有一個特定的問題，你正在或正在工作，但你只是想放心，你正在使用這種設計的最佳做法？ – Dancreek

我只是想確保這是設計應用程序的最佳方式。我不知道如何設置第二個視圖控制器，將元素添加到數組中並將它們顯示在列中。 – user1034642

將5個文本字段放在視圖中是不是更容易？我不明白你爲什麼把它們放在一個表格視圖中......如果你希望它們是可滾動的，你總是可以在滾動視圖中包裝你的整個視圖，但是我不會用表格來做到這一點。據我所知，使用表視圖進行輸入通常是不好的。這更像是爲用戶提供一些數據的顯示，例如一個對象數組。此外，通常，如果您使用NSMutableArray作爲數據源，則還希望表格數據源方法（如tableView:numberOfRowsInSection:）根據數組大小返回一個值，而不是一個神奇的硬編碼數字。

我也看到你在代碼中做了很多工作。您可以讓Interface Builder爲您完成所有這些工作：只需創建一個新的UIViewController子類，並使用一個名稱相同的xib，在Interface Builder中進行設計，然後將該邏輯寫入.m文件。

例如，假設我有UIViewController子類，稱爲MyViewController，這與1個按鈕「下一個」和2個UITextField S，通稱爲dateTF和scoreTF視圖。我的.h文件看起來是這樣的：

#import <UIKit/UIKit.h> 

@interface MyViewController : UIViewController { 
    IBOutlet UITextField *dateTF; 
    IBOutlet UITextField *scoreTF; 
} 

@property (nonatomic, retain) UITextField *dateTF; 
@property (nonatomic, retain) UITextField *scoreTF; 

- (IBAction)clickedNext:(id)sender; 

@end

下面我們就針對當按下「下一步」按鈕，將被稱爲動作的佔位符，2個出口到文本字段檢索數據他們。我不需要IBOutlet按鈕，因爲我不會編輯它。

.m文件看起來是這樣的：

#import "MyViewController.h" 

@implementation MyViewController 

@synthesize dateTF 
@synthesize scoreTF; 

// called when the button is clicked 
- (IBAction)clickedNext:(id)sender{ 
    NSString * date = self.dateTF.text; 
    NSString * score = self.scoreTF.text; 
    // do something with this data, like put up a model and go to the next view 
} 

@end

這是假設我有一個包含我的UI中的廈門國際銀行文件。在xib中，您還需要創建一些連接（使用ctrl + click_and_drag輕鬆實現從源到目標，例如從按鈕到文件所有者）：您需要連接2個IBOutlets和該按鈕來調用IBAction，你應該很好走。

希望這會有所幫助！

感謝您的幫助，但我從來沒有學會如何使用界面構建器。我被教導要以一切方式進行。我想我會像你說的那樣放5個文本框。 – user1034642

我用數據字典中傳遞數據到一個新的viewController，並取消對代碼中的m：

/* 
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { 
     // Custom initialization 
    } 
    return self; 
} 
*/

，並添加新的參數在我的案件的字典：

假設名稱爲passDataHereController和selectedNews在你要去哪裏來傳遞數據控制器聲明的NSDictionary在.H

// Note that I added the withDataDictionary:(NSDictionary*)passedDataDictionary 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil withDataDictionary:(NSDictionary*)passedDataDictionary{ 
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { 
     // Custom initialization 
     self.selectedNews = passedDataDictionary; 
    } 
    return self; 
}

然後

//supposed dataTobePassed is already populated 
    passDataHereController *newView = [[passDataHereController alloc] initWithNibName:@"passDataHereController" bundle:nil withDataDictionary:dataTobePassed]; 
    [self.navigationController pushViewController:newView animated:YES]; 
    [newView release];

這是將數據傳遞到另一個視圖的一種方式，其他視圖可能有更簡單的解決方案。希望它有幫助。
