我在將數據從unwind segue變爲NSMutableArray對象時遇到了一些麻煩。當我將NSLog從unwind segue中取出時,它顯示信息存在,它只是不會在我的數組中顯示在表視圖中。我的問題是什麼?感謝大家。將Segue放到一個NSMutableArray對象中
#import "ChoicesViewController.h"
#import "MyDataChoices.h"
#import "AddChoiceViewController.h"
@interface ChoicesViewController() <UITableViewDelegate,UITableViewDataSource>
@property (weak, nonatomic) IBOutlet UITableView *myTableView;
@property (strong, nonatomic) NSMutableArray *arrayNames;
@property (strong, nonatomic) NSArray *sections;
@end
@implementation ChoicesViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.myTableView.delegate = self;
self.myTableView.dataSource = self;
self.sections = [NSArray arrayWithObjects:@"A", @"B", @"C", @"D", @"E", @"F", @"G", @"H", @"I", @"J", @"K", @"L", @"M", @"N", @"O", @"P", @"Q", @"R", @"S", @"T", @"U", @"V,", @"W", @"X", @"Y", @"Z", nil];
self.arrayNames = [[NSMutableArray alloc] init];
[self.arrayNames addObjectsFromArray:@[
[MyDataChoices itemWithNewName:@"Apples"],
[MyDataChoices itemWithNewName:@"Bread"]]];
}
- (IBAction)unwindSegueToChoices:(UIStoryboardSegue *)segue
{
AddChoiceViewController *sourceVC = segue.sourceViewController;
NSString *myNewItem = sourceVC.myTextField.text;
//NSString *myFinalString = [[myNewItem substringToIndex:1] capitalizedString];
NSString *capitalizedString = [myNewItem capitalizedString];
NSLog(capitalizedString);
//Why will this not work?
[self.arrayNames addObject:capitalizedString];
}
-(NSInteger) numberOfSectionsInTableView:(UITableView *) tableView
{
return 1;
}
-(NSInteger) tableView:(UITableView *) tableView numberOfRowsInSection:(NSInteger)section
{
return self.arrayNames.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyDataChoices *currentRow = self.arrayNames[indexPath.row];
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"mainCell2" forIndexPath:indexPath];
cell.textLabel.text = currentRow.myNameChoices;
return cell;
}
因此,如果您登錄self.arrayNames作爲unwindSegueToChoices最後一行它表明capitalizedString不添加(或者你只是沒有看到它在你的表格視圖)? – rdelmar 2014-10-10 00:15:06
