下面一段代碼被成功構建,並且對我來說似乎也很好,但不起作用......請注意,我是關鍵值編碼的新手,您的幫助將不勝感激。 .. 在表視圖委託didSelectRowAtIndexPath方法:方法 這裏categoriesList與5個條目NSUnknownKeyException,KVC合規性代碼不能正常工作
NSUInteger row = [indexPath row];
NSString *rowString = [categoriesList objectAtIndex:row];
NSString *path = [[NSBundle mainBundle] pathForResource:@"DataBase" ofType:@"plist"];
NSDictionary *rootDict = [[NSDictionary alloc] initWithContentsOfFile:path];
NSArray *allRootKeys = [rootDict allKeys];
NSMutableArray *mutableArray = [[NSMutableArray alloc] init];
for (NSString *name in allRootKeys) {
NSInteger index = [allRootKeys indexOfObject:name];
NSDictionary *newDict = [allRootKeys objectAtIndex:index];
if ([newDict valueForKey:@"Class"] == rowString)
[mutableArray addObject:[allRootKeys objectAtIndex:index]];
}
NSArray *childControllerArray = [[NSArray alloc] initWithArray:mutableArray];
現在我通過childControllerArray我的下一個控制器的loadArray的ivar當與被選擇的行它獲取推一個簡單的表它顯示該數組的內容.... 當我刪除上面的代碼,並通過一個簡單的數組對象添加到其中,它工作得很好.... PLEASE HELP
給出的例外是:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSCFString 0x543eb0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key Class.
它可以和工作,但存儲在newDict的值不是當然一個NSDictionary:P – rpetrich 2009-06-18 08:17:58
