嗨我的用戶界面選擇器不再適用於iOS7,它彈出但它是空白的。只發生在iOS7上。UIPicker和UIActionsheet不再工作iOS7
//picker
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
animationsLabel.text = [optionsArray objectAtIndex:[picker selectedRowInComponent:0]];
if (pickerView==animationsPicker) {
animationsLabel.text = [optionsArray objectAtIndex:[animationsPicker selectedRowInComponent:0]];
}
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
return [optionsArray count];
}
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
return [optionsArray objectAtIndex:row];
NSLog(@"title options array %lu",(unsigned long)optionsArray.count);
}
和動作:
-(IBAction)animationActionSheet:(id)sender {
UIActionSheet *selectPopup = [[UIActionSheet alloc] initWithTitle:@"\n\n\n\n\n\n\n\n"
delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
[selectPopup showInView:self.view];
optionsArray = [[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"6",@"5",@"7",@"8",@"9", nil];
// Create picker
animationsPicker = [[UIPickerView alloc] initWithFrame:CGRectMake(10, 160, 320, 100)];
animationsPicker.showsSelectionIndicator = YES;
[self.view addSubview:animationsPicker];
animationsPicker.delegate = self;
animationsPicker.dataSource = self;
[selectPopup addSubview:animationsPicker];
// Animate picker opening
[UIView beginAnimations:nil context:nil];
[selectPopup setBounds:CGRectMake(0, 0, 320, 485)];
[UIView commitAnimations];
}
這是我到目前爲止已經試過。之前在操作表單中顯示選取器時沒有問題,但現在它是空白的。我想知道有沒有其他人遇到這個問題,或者你能看到任何錯誤?我將所有內容都印刷在選取器上。
非常感謝。我希望不是這樣,但它應該很容易解決。我希望保持它一樣。再次感謝。 – DevC
我也希望這樣做,但把它們放在UIViews而不是ActionSheets中並不壞。祝你好運! – user1509295
