本周推出了iOS 7 Beta,每当更新发布时,这些都必须更新应用程序以兼容性设置一些错误.
好吧,我在我的iPhone上安装了iOS 7并且应用程序原理完美运行,然后安装了Xcode 5(预览版)并编译了我的项目,我意识到新的statusBar现在完全平静,你的视图控制器将显示为她的背景.
这就是出现问题的地方,屏幕底部有一个20px的白色条带,由于视图控制器赢得了曾经是statusBar的空间.
如果我在我的故事板中修复此问题就可以了,但是由于20px statusBar,iOS 6中的问题仍然存在,屏幕将被切断.
我认为简单的解决方案是在启动时检查iOS的版本并根据每个创建一个故事板.在我的项目中,我有3个故事板,iPhone 3.5','iPhone 4'和'iPad'.很快就要创建3个故事板,因为这20个px.
那将是最好的解决方案吗？我还有其他选择吗？
抱歉,长篇文章.欢迎任何帮助!
我尝试使用Stig的JSON库发出HTTP请求并解析JSON.我收到此错误'autorelease'不可用:当我使用此代码时,在自动引用计数模式下不可用
NSURLRequest *request2;
request2 = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://sandbox.CompanyName.com/api/%@/users/%@/user_badges?url=CompanyName.map2.com&amount=999999999999",[information stringForKey:@"apiKey"] , [information stringForKey:@"userID"]]]];
NSURLConnection *connection2;
connection2 = [[NSURLConnection alloc] initWithRequest:request2 delegate:self startImmediately:YES];
NSURLResponse *resp2;
NSData *cData2 = [NSURLConnection sendSynchronousRequest:request2 returningResponse:&resp2 error:nil];
NSString *cDataString2 = [[NSString alloc] initWithData:cData2 encoding:NSUTF8StringEncoding];
NSLog(@"getUsersBadges called");
NSError *error4;
SBJSON *json4 = [[SBJSON new] autorelease];
// NSArray *luckyNumbers = [json objectWithString:responseString error:&error];
NSDictionary *luckyNumbers4 = [json4 objectWithString:cDataString2 error:&error4];
[cDataString2 release];
UPDATE
对于任何感兴趣的人,这是正确的代码:NSURLRequest*request2; request2 = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@" http://sandbox.CompanyName.com/api/%@/users/%@/user_badges?url=CompanyName.map2.com&ount =999999999999 ",[ information stringForKey:@"apiKey"],[information stringForKey:@"userID"]]]];
NSURLConnection *connection2;
connection2 …我试图将字符串设置为"如果[object objectForKey @"display_name"]为NULL,则为"无显示名称".它在日志中崩溃了

我正在尝试使用此代码 audioPlayer.currentTime = nowPlayingSlider.value;
我收到此错误:
Setter method is needed to assign to object using property assignment syntax
我如何让它工作.
我想使用AVAudioPlayer依次播放多个MP3文件(一个接一个).我试了一下,播放完第一张MP3后就停止了.但是,如果我进入调试器,它工作正常..任何想法？我在某处读到AVAudioPlayer在后台播放音频..我该如何阻止它这样做？沃什
我正在制作一个 iPhone 应用程序，并想为 AVPlayer 制作一个搜索栏。我想用 UISlider 来实现。我怎样才能做到这一点？
我在我的应用程序中使用FB Open Graph.它没有完全发挥作用.当我发布一个对象时,它出现在用户最近的活动中; 但是,它没有出现在他们的时间表上.元数据没有错误,我正在使用FBGraph gem但是当我使用curl时它也不起作用.有任何建议来解决这个问题吗？
我在回形针方面遇到了一些问题.当我有一个跟随大小的"#"(缩放和裁剪)时,我得到422错误.我的日志说明了这个:
Command :: convert '/tmp/**** (20130110)20130311-13571-xxasmt.png[0]' -auto-orient -resize "150x150#" '/tmp/**** (20130110)20130311-13571-xxasmt20130311-13571-1anrx0y'

Completed 422 Unprocessable Entity in 2785ms (Views: 0.8ms | ActiveRecord: 9.1ms)
这是我在模型中的回形针代码:

我错过了什么吗？
