触摸时UITextField崩溃

Question

我在调试时遇到问题。我有一个触摸时崩溃的UITextView。其中只有一部分崩溃如：账户类型和增值税季度结束。 这是崩溃时屏幕的样子：

这是代码：

 @synthesize txtAccType = _txtAccountType;

- (void)viewDidLoad {
  [super viewDidLoad];
  arrAccountType = [[NSMutableArray alloc] initWithObjects:@"Freelancers", nil];

  //self.title = @"Account Setting";
  self.title = NSLocalizedString(@"AccountSetting", nil);

  self.navigationItem.rightBarButtonItem = self.doneBarButtonItem;

  arrCatId = [[NSMutableArray alloc] init];
  arrCategory = [[NSMutableArray alloc] init];
  arrTotal = [[NSMutableArray alloc] init];

  tag = 0;
  [svAccountSetting setContentSize:CGSizeMake(280, 600)];
  arrCsvData = [[NSMutableArray alloc] init];

  quarterEndDatesArray = [[NSArray alloc] initWithObjects:
                 @"April/Jul/Oct/Jan",
                 @"May/Aug/Nov/Feb",
                 @"June/Sep/Dec/Mar", nil];

  [self setAcc];
}

-(IBAction)selectAccountType
{
  [self.txtAccType resignFirstResponder];
  [svAccountSetting setContentOffset:CGPointMake(0, 6) animated:YES];
  [ActionSheetPicker displayActionPickerWithView:self.view data:arrAccountType selectedIndex:self.selectedIndex target:self action:@selector(itemWasSelected:) title: NSLocalizedString(@"Select_Account_Type", nil) ];
}

- (void)itemWasSelected:(NSNumber *)selectedIndexs {
  //Selection was made
  self.selectedIndex = [selectedIndexs intValue];
  self.txtAccType.text = [arrAccountType objectAtIndex:self.selectedIndex];
}

由于这个项目较旧，我想知道一些经验丰富的iOS开发人员是否能够提供帮助。

Answer 1

首先尝试将selectedIndex设置为0：

[ActionSheetPicker displayActionPickerWithView:self.view data:arrAccountType selectedIndex:0 target:self action:@selector(itemWasSelected:) title: NSLocalizedString(@"Select_Account_Type", nil) ];

Answer 2

此方法在触摸UITextView时崩溃

[ActionSheetPicker displayActionPickerWithView：self.view data：arrAccountType selectedIndex：self.selectedIndex target：self action：@selector（itemWasSelected :) title：NSLocalizedString（@＆＃34; Select_Account_Type＆＃34;，nil）];
