Question

当我使用Realm存储我的数据时，就像

一样

[applicat.realm beginWriteTransaction];

NSArray *bankCards = [XXXBankCard createOrUpdateInRealm:applicat.realm withJSONArray:cards];
[applicat.bankCards removeAllObjects];
[applicat.bankCards addObjects:bankCards];

[applicat.realm commitWriteTransaction];

我的Fabric获得了很多崩溃

崩溃：com.apple.main-thread EXC_BAD_ACCESS KERN_PROTECTION_FAILURE 0x0000000108ad421c

applicat是XXXApplicat的实例：

@interface XXXApplicat : RLMObject
@property(nonatomic, copy) NSString * uid;
@property(nonatomic, strong) RLMArray<XXXBankCard> * bankCards;
@end

applicat.realm等于applicat.bankCards.realm。我初始化applicat的地方是：

- (XXXApplicat *)applicat {
    if (self.realm == nil) {
        return nil;
    }

    if (_applicat == nil) {
        _applicat = [XXXApplicat objectInRealm:self.realm forPrimaryKey:self.userId];

        if (_applicat == nil) {
            _applicat = [XXXApplicat new];
            _applicat.uid = self.userId;

            [self.realm beginWriteTransaction];
            [self.realm addObject:_applicat];
            [self.realm commitWriteTransaction];
        }

        [self addObserverToApplicat:_applicat];
    }

    return _applicat;
}

整个崩溃日志是：

Answer 1

您看到的崩溃是an issue in older versions of Realm Objective-C。它在v0.97.0中修复。更新到较新版本的Realm应解决此崩溃问题。

领域，commitWriteTransaction，EXC_BAD_ACCESS KERN_PROTECTION_FAILURE
