[英]NSLog not returning consistent results
我有一個NSLog問題,在加載之間它不會保持相同的結果。 它非常令人沮喪,但是如果有人可以闡明一些想法,那將是非常不錯的。 我正在嘗試從我的應用程序委托中調用數組
NSLog(@"Selected Team 1 : %@", [[[appDelegate teamRoster]objectAtIndex:1] class]);
NSLog(@"Selected Team 0 : %@", [[[appDelegate teamRoster]objectAtIndex:0] class]);
NSLog(@"Selected Team : %@", [[[appDelegate teamRoster]objectAtIndex:indexPath.row] class]);
NSLog(@"Selected Team : %@", [[appDelegate teamRoster]objectAtIndex:indexPath.row]);
並連續三次將這些退貨

2011-06-22 09:59:17.828 CoCoach[33192:207] Selected Team : <_UITableViewReorderingSupport: 0x5b3cf30>
另外,當我只是查看數組中的內容時,我得到以下內容。
2011-06-22 09:58:30.078 CoCoach[33189:207] Team Roster Array: (
"Koch",
"Smith"
)
完全符合預期。
是什么賦予了? 有任何想法嗎。 謝謝。
更新:添加數組的函數
- (void)fetchRecords:(NSString *)teamToFind{
teamRoster = [[NSMutableArray alloc] init];
NSManagedObjectContext *context = [self managedObjectContext];
// Define our table/entity to use
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Teams" inManagedObjectContext:context];
// Setup the fetch request
NSFetchRequest *request = [[NSFetchRequest alloc] init];
[request setEntity:entity];
// Define how we will sort the records
NSSortDescriptor *teams = [[NSSortDescriptor alloc] initWithKey:@"Team" ascending:NO];
NSArray *sortDescriptors = [NSArray arrayWithObject:teams];
[request setSortDescriptors:sortDescriptors];
[teams release];
// Fetch the records and handle an error
NSError *error;
NSMutableArray *mutableFetchResults = [[context executeFetchRequest:request error:&error] mutableCopy];
if (!mutableFetchResults) {
// Handle the error.
// This is a serious error and should advise the user to restart the application
}
// Save our fetched data to an array
[self setStoredTeams:mutableFetchResults];
NSLog(@"Number of teams, %i", [storedTeams count]);
// NSMutableArray *temp = [[NSMutableArray alloc] init];
for (Teams *diffTeams in storedTeams) {
NSLog(@"Name: %@", diffTeams.Team);
NSSet *rowers = [[NSSet alloc] initWithSet:diffTeams.Rowers];
for (Rowers *roster in rowers){
if ([diffTeams.Team isEqualToString:teamToFind]) {
NSString *fullName = [NSString stringWithFormat:@"%@ %@", roster.FName, roster.LName];
NSLog(@"%@", fullName);
[teamRoster addObject:fullName];
[fullName release];
NSLog(@"Team Roster Array: %@", teamRoster);
}
}
}
if (![context save:&error]) {
//This is a serious error saying the record could not be saved.
//Advise the user to restart the application
}
[mutableFetchResults release];
[request release];
}
我認為您想在NSLog
參數中使用NSStringFromClass([[[appDelegate teamRoster]objectAtIndex:1] class])
。
我正在釋放放入對象的NSString,但是在for循環中,對象已創建並再次釋放
