UIPickerView不工作在IOS 8

UIPickerView不工作在IOS 8，但它的工作在IOS 7沒有錯誤，這裏是我的代碼一個陣列，具有名字myArray的載荷pickerviewUIPickerView不工作在IOS 8

- (void)viewDidLoad 
{ 
    [sliderView addSubview:_myPickerView]; 

    txtstreet.inputView=_myPickerView; 
    myArray = arrwithdata; 
} 

- (NSInteger)numberOfComponentsInPickerView: (UIPickerView *)pickerView 
{ 
     return 1; 
} 

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component 
{ 

return [myArray count]; 

} 

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)rowForComponent:(NSInteger)component 
{ 
    return myArray[row]; 
} 

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row 
    inComponent:(NSInteger)component 
{ 

    NSString *resultString = [[NSString alloc] initWithFormat:@"%@", myArray[row]]; 
    txtstreet.text = resultString; 
}

它在運行數據ios7 這是在IOS 8中運行時出錯設備

你是否正在使用工作表來顯示選取器？ – 2014-10-17 10:11:06

不，只顯示Picker View – Ujesh 2014-10-17 10:23:19

我解決了這個問題，通過編程取代視圖，問題在我看來，因爲我創建了兩個視圖一個是主要的和se cond是sliderview，呼籲從視圖中選取器滑塊觀點，現在我的代碼是這個樣子

- (void)viewDidLoad 
{ 
UIPickerView *myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 200, 320, 200)]; 
myPickerView.delegate = self; 
myPickerView.showsSelectionIndicator = YES; 
//[sliderView addSubview:_myPickerView]; 

txtstreet.inputView=_myPickerView; 
myArray = arrwithdata; 
}

和其他代碼是相同的......它在這兩個操作系統的工作。

嘗試一個如果兩件事。

從viewdidLoad方法刪除

[sliderView addSubview:_myPickerView];

此代碼。

如果不是把這些代碼拿過來，頁頭和初始化您鑑於pickerview做負載方法

_myPickerView = [UIPickerVuew alloc]init]

嘗試不起作用。

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) { 

    alertController = [UIAlertController alertControllerWithTitle:nil 
                  message:@"\n\n\n\n\n\n\n\n\n\n" 
                preferredStyle:UIAlertControllerStyleActionSheet]; 
    //pickerView.frame=CGRectMake(0, 0, 120, 30); 
    UIView *toolView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 305.0f, 44.f)]; 
    toolView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"blank-headerNew.png"]]; 
    CGRect buttonFrame = CGRectMake(220, 5, 70, 30); 
    UIButton *selButton = [[UIButton alloc] initWithFrame:buttonFrame]; 
    //[selButton setBackgroundImage:[UIImage imageNamed:@"red_bgnew.png"] forState:UIControlStateNormal]; 
    [selButton setTitle:@"Done" forState:UIControlStateNormal]; 
    [selButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
    [toolView addSubview:selButton]; 
    [alertController.view addSubview:pickerView]; 
    [alertController.view addSubview:toolView]; 
    [self presentViewController:alertController animated:YES completion:nil]; 
}
