Ios 通知应用程序崩溃

我正在尝试将

NSMutableDictionary

传递给

NSNotification

传递给其他类。 但是当发布

NSMutableDictionary

时，应用程序崩溃。 有人能帮忙吗？ 我正在尝试这个

NSMutableDictionary *temp = [[NSMutableDictionary alloc]init];

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding];
temp =  [responseString JSONValue];
NSLog(@"webdata is %@",temp);
NSLog(@"inside usersignup success");
[[NSNotificationCenter defaultCenter] postNotificationName:CNotifySignupSucess object:temp];
[temp release];

首先，您需要阅读一些iOS编程基础知识。以及

NSMutableDictionary *temp = [[NSMutableDictionary alloc]init];

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding];
temp =  [responseString JSONValue]; //----> this line is wrong

因为，

temp

指针指向新创建的

NSMutableDictionary

对象，所以您将其重新分配给

JSONValue

方法返回的另一个对象，即

autorelease

对象，而您不拥有它，因此无法

释放它。实现您想要的目标的一些更好的方法是：

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding];
    NSMutableDictionary *temp =  [responseString JSONValue];
    NSLog(@"webdata is %@",temp);
    NSLog(@"inside usersignup success");
    [[NSNotificationCenter defaultCenter] postNotificationName:CNotifySignupSucess object:temp];
    //NO RELEASING the AUTORELEASE OBJECT!!!!

或：

或：

在最后两种情况下，我考虑
JSONValue
方法返回
NSDictionary
。祝你好运
 [[NSNotificationCenter defaultCenter]添加观察者：自选择器：@selector（SignupSussReceived:）名称：CNotifySignupSucess对象：nil]；NSMutableDictionary*dict=notification.object；如果（[[dict objectForKey:@“Success”]IseQualtString:@“1”]）{appDelegate.islogin=TRUE；self.title=nil；[appDelegate.userinfo setObject:[dict objectForKey:@“user_id”]forKey:@“userid”]；NSSERDEFAULTS*defaults=[NSSERDEFAULTS standardUserDefaults]；NSString*STRENTMP=[NSString STRING stringWithFormat:@“%@”，[dict objectForKey:@“user_id”]；[defaults setObject:strtemp forKey:@“userid”]；崩溃仅显示objc版本
