我们已经在应用商店提交了该应用，并获得了批准。但是一天后我们发现它在 iOS 5 和 6 上运行良好，但在 iOS7 上却崩溃了。

以下是崩溃日志。

代码

 NSLog(@"View will appear");
        NSLog(@" --- >>>>>   hasEnteredInAppFirstTime ::: %u", [mClient hasEnteredInAppFirstTime]);
        if([mClient hasEnteredInAppFirstTime]) {
            mClient.hasEnteredInAppFirstTime = NO;

            NSLog(@"Default Screen %@", mClient.defaultScreen);
            if([mClient defaultScreen] == (id)[NSNull null] || [mClient defaultScreen].length == 0 ) {

                NSLog(@"Default screen is nil, going to load dashboard");
                [mClient setUPProgressHUDForView:self.view withLable:@"Generating Dashboard" andMessage:@"Please Wait.."];
                for(UIView *subview in [self.scrollView subviews]) {
                    [subview removeFromSuperview];
                }
                NSLog(@"-->    :::  Going to change here");
                [self generateDashboard];
            } else {
                NSLog(@"Going to push default screen : %@", mClient.defaultScreen);
                //[mClient setUPProgressHUDForView:self.view withLable:@"Loading Default Screen" andMessage:@"Please Wait.."];
                [self pushDefaultScreen:mClient.defaultScreen];
            }
        }

请帮助我，让我知道问题是什么，为什么会崩溃以及解决方案是什么。

当你改变它时，你正在改变一个数组：

for(UIView *subview in [self.scrollView subviews]) {
   [subview removeFromSuperview];
}

您应该制作子视图数组的副本，并将消息发送到其中的每个对象：

NSArray *oldSubviews = [self.scrollView.subviews copy];
for(UIView *subview in oldSubviews) {
   [subview removeFromSuperview];
}

我正在访问 另一个类的mClient defaultScreen 属性。并且在 defaultScreen 中设置值时，我没有使用此运算符和属性名称。这在 iOS6 中运行良好，但在 iOS7 中导致崩溃。

mClient中的上一行代码： defaultScreen = @"screen name";

新代码： this.defaultScreen = @"screen name";

现在崩溃是固定的。:-)
