所以我不知道为什么我会收到这个错误。错误信息如下:
* 由于未捕获的异常“RLMException”而终止应用程序,原因:“尝试在写入事务之外修改对象 - 首先在 RLMRealm 实例上调用 beginWriteTransaction。” * First throw call stack: (0x2f7b0f83 0x39f61ccf 0xc46ef 0xc3c23 0xc0c9d 0xb3e73 0x3a449833 0x3a449ded 0x3a44a297 0x3a45c88d 0x3a45cb21 0x3a58bbd3 0x3a58ba98) libc++abi.dylib: terminating with uncaught exception of type NSException
并在执行此代码时抛出。
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
UITextField * alertTextField = [alertView textFieldAtIndex:0];
if (![self.chatSession.theirAlias isEqualToString:alertTextField.text]) {
self.sender = alertTextField.text;
dispatch_queue_t queue = ((AppDelegate *)[UIApplication sharedApplication].delegate).queueForWrites;
dispatch_async(queue, ^{
[[RLMRealm defaultRealm] beginWriteTransaction];
self.chatSession.myAlias = alertTextField.text; // This is the line where the error is thrown
[[RLMRealm defaultRealm] commitWriteTransaction];
});
} else {
[self promptForAliasAfterRejection];
}
}
很明显,我正在写事务内部。这是Realm的错误吗?还是我错过了什么……?
