Ich habe ein seltsames Problem mit einer App, die perfekt auf iOS arbeitet < 10.IOS 10 Kerndaten executeFetchRequest Abstürze genannt, wenn sie vor insertNewObjectForEntityForName
Nachdem das Telefon auf iOS 10 aktualisiert haben, meine app stürzt ab, wenn ein executeFetchRequest tun vor insertNewObjectForEntityForName.
Es scheint vor allem iPhone6 und höher, die das Problem haben (wurde gesagt, dass iPhone5 ist in Ordnung).
Es ist in dieser Zeile im Code unten Absturz:
NSArray *results = [context executeFetchRequest:fetchRequest error:&error];
xcode error picture Diese Methoden gibt mir Kopfschmerzen in 'Scada' Klasse:
+(Scada *)getFirstScada {
NSError *error = nil;
NSArray *results = [context executeFetchRequest:fetchRequest error:&error]; //Crashing here
Scada *retVal = nil;
//maybe some check before, to be sure results is not empty
if ([results count] == 0) {
retVal = nil;
} else {
retVal = [results firstObject];
}
return retVal;
}
+ (int)insertNewScada:(NSString *)scadaName HostName:(NSString *)scadaHostName {
int returnValue = 0;
Scada *newScada = [NSEntityDescription insertNewObjectForEntityForName:NSStringFromClass([Scada class]) inManagedObjectContext:context];
//Configure the new scada object.
[newScada setName:scadaName];
[newScada setHostname:[scadaHostName uppercaseString]];
// Save the context.
NSError *error = nil;
if (![context save:&error]) {
NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
returnValue = -1;
} else {
returnValue = 1;
}
return returnValue;
}
Mein Anruf heute sind, wie dies in AppDelegate:
Funktioniert nicht:
Scada *scada = [Scada getFirstScada];
Works:
[Scada insertNewScada:@"tmp" HostName:@"T.E.M.P/DELETE"];
[Scada removeScada:@"T.E.M.P/DELETE"];
Scada *scada = [Scada getFirstScada];
