運が悪かったので、しばらくの間この答えを探していました。GoogleからStackOverflowへ。私がこれまでに見つけた唯一の答えは、単にinitではなく、ビューでinitWithFrameを呼び出すように人々に指示しています。UIViewsでのinitへのすべての呼び出しをinitWithFrameに置き換えましたが、うまくいきません。
私はIBを使用していません。
これが私のコード全体です：
@interface UnlockKeyboard : UIView
{
NSArray *buttons;
UITextField *passcodeFields;
UIImage *buttonBackgroundImage;
UIImage *buttonBackgroundHighlightedImage;
UIImage *middleButtonBackgroundImage;
UIImage *middleButtonBackgroundImageHighlighted;
UIImage *screenBackgroundImage;
UIImage *keypadViewBackgroundImage;
UIView *infoView;
UIView *keypadView;
}
@property(nonatomic, retain)UIImage *buttonBackgroundImage;
@property(nonatomic, retain)UIImage *buttonBackgroundHighlightedImage;
@property(nonatomic, retain)UIImage *screenBackgroundImage;
@property(nonatomic, retain)UIImage* keypadViewBackgroundImage;
@end
@implementation UnlockKeyboard
@synthesize buttonBackgroundImage = _buttonBackgroundImage;
@synthesize buttonBackgroundHighlightedImage = _buttonBackgroundHighlightedImage;
@synthesize screenBackgroundImage = _screenBackgroundImage;
@synthesize keypadViewBackgroundImage = _keypadViewBackgroundImage;
-(id)init
{
if((self = [super initWithFrame:CGRectMake(0, 0, 320, 480)]))
{
_unlockKeyboardBundle = [NSBundle bundleForClass:[self class]];
buttonBackgroundImage = [UIImage imageWithContentsOfFile:[_unlockKeyboardBundle pathForResource:@"button" ofType:@"png"]];
middleButtonBackgroundImage = [UIImage imageWithContentsOfFile:[_unlockKeyboardBundle pathForResource:@"middleButton" ofType:@"png"]];
buttonBackgroundHighlightedImage = [UIImage imageWithContentsOfFile:[_unlockKeyboardBundle pathForResource:@"pushedButton" ofType:@"png"]];
middleButtonBackgroundImageHighlighted = [UIImage imageWithContentsOfFile:[_unlockKeyboardBundle pathForResource:@"pushedButtonMiddle" ofType:@"png"]];
keypadView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

[button7 setTitle:@"7" forState:UIControlStateNormal];
button7.frame = CGRectMake(0, 361, 106, 50);

-(void)dealloc

ご覧のとおり、UnlockKeyboardを使用してUIViewをサブクラス化します。UnlockKeyboardには、すべてのUIButtonを含む別のサブビュー（keypadView）が必要です。したがって、すべてのkeyboardViewはUnlockKeyboardsのサブビューであり、これらのボタンはすべてkeyboardView内にある必要があります。うまく追加できますが、タップしても制御状態が変わりません。はい、ご覧のとおり、UIViewを作成するときに、initへのすべての呼び出しをinitWithFrameに置き換えました。
これに関するどんな助けも本当にありがたいです。
