Ios 更新领域上的对象

我想用realm更新一个对象。但我的应用程序正在崩溃

我的代码：

var findConversations = ShufflePerson.objectsWhere("receiver='\(from)'")
var shuf = findConversations[0] as! ShufflePerson
shuf.unreadMessage=shuf.unreadMessage++
self.realm.beginWriteTransaction()
self.realm.commitWriteTransaction()

Terminating app due to uncaught exception 'RLMException', reason: 'Attempting to modify object outside of a write transaction - call beginWriteTransaction on an RLMRealm instance first.'

崩溃日志：

var findConversations = ShufflePerson.objectsWhere("receiver='\(from)'")
var shuf = findConversations[0] as! ShufflePerson
shuf.unreadMessage=shuf.unreadMessage++
self.realm.beginWriteTransaction()
self.realm.commitWriteTransaction()

Terminating app due to uncaught exception 'RLMException', reason: 'Attempting to modify object outside of a write transaction - call beginWriteTransaction on an RLMRealm instance first.'

如何修复？

请尝试以下操作：

var findConversations = ShufflePerson.objectsWhere("receiver='\(from)'")
var shuf = findConversations[0] as! ShufflePerson
self.realm.beginWriteTransaction()
shuf.unreadMessage++
self.realm.commitWriteTransaction()

正如异常消息所说，问题在于您正在写事务之外修改对象。在事务内部进行这种变异应该可以做到这一点
