時,我有一個tableview中細胞的文本字段,我想指定自定義輸入鍵盤。我可以讓鍵盤出現,但似乎相應的控制器類沒有連接。當我按下任何按鈕時,出現EXC_BAD_ACCESS錯誤或「無法識別的選擇器」錯誤。EXC_BAD_ACCESS錯誤切換到ARC
這裏是我綁的tableview細胞的文本字段的自定義輸入鍵盤代碼
CustomNumberPadViewController *calcKeyboard = [[CustomNumberPadViewController alloc] initWithNibName:@"CustomNumberPadView" bundle:nil];
calcKeyboard.equationViewController = self;
cell.variableValue.inputView = calcKeyboard.view;
我有動作方法綁在calkKeyboard的按鈕,當我按下按鈕,這些方法都沒有被稱爲。我甚至實例化了一個「viewWillAppear」方法,當鍵盤出現時也不會調用它。
我已經檢查了類數字小的,它被連接到CustomNumberPadViewController,其包含上述方法。
這裏是我的CustomNumberPadViewController代碼:
#import <UIKit/UIKit.h>
#import "EquationViewController.h"
@class EquationViewController;
@interface CustomNumberPadViewController : UIViewController <UITextFieldDelegate>{
EquationViewController *equationViewController;
}
@property (nonatomic, strong) EquationViewController *equationViewController;
-(IBAction)buttonPressed:(id)sender;
-(IBAction)buttonDonePressed:(id)sender;
-(IBAction)buttonDelPressed:(id)sender;
@end
和相關的實施(爲簡便起見,我切出的動作方法的膽量和剛剛離開我的調試日誌):
#import "CustomNumberPadViewController.h"
#import "VariableCellController.h"
@implementation CustomNumberPadViewController
@synthesize equationViewController;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
}
return self;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
-(void) viewWillAppear:(BOOL)animated
{
UIColor *backgroundPatern = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"calculatorBackground.png"]];
self.view.backgroundColor = backgroundPatern;
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
#pragma mark - Action Methods
-(IBAction)buttonPressed:(id)sender{
NSLog(@"61-CNPVC");
}
-(IBAction)buttonDonePressed:(id)sender{
NSLog(@"117-CNPVC");
}
-(IBAction)buttonDelPressed:(id)sender{
NSLog(@"125-CNPVC");
}
@end
這樣做,我試圖讓它成爲一個屬性,但必須弄糟一些語法,並繼續其他一些想法。萬分感謝。有趣的是,當我沒有使用ARC時,我沒有這個問題。但我想我確實有內存泄漏... – Jbryson 2012-03-08 20:11:53
