时,我有一个tableview中细胞的文本字段,我想指定自定义输入键盘。我可以让键盘出现,但似乎相应的控制器类没有连接。当我按下任何按钮时,出现EXC_BAD_ACCESS错误或“无法识别的选择器”错误。EXC_BAD_ACCESS错误切换到ARC
这里是我绑的tableview细胞的文本字段的自定义输入键盘代码
CustomNumberPadViewController *calcKeyboard = [[CustomNumberPadViewController alloc] initWithNibName:@"CustomNumberPadView" bundle:nil];
calcKeyboard.equationViewController = self;
cell.variableValue.inputView = calcKeyboard.view;
我有动作方法绑在calkKeyboard的按钮,当我按下按钮,这些方法都没有被称为。我甚至实例化了一个“viewWillAppear”方法,当键盘出现时也不会调用它。
我已经检查了类数字小的,它被连接到CustomNumberPadViewController,其包含上述方法。
这里是我的CustomNumberPadViewController代码:
#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
和相关的实施(为简便起见,我切出的动作方法的胆量和刚刚离开我的调试日志):
#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
这样做,我试图让它成为一个属性,但必须弄糟一些语法,并继续其他一些想法。万分感谢。有趣的是,当我没有使用ARC时,我没有这个问题。但我想我确实有内存泄漏... – Jbryson 2012-03-08 20:11:53
