如何为ios7＆amp;创建UIButton适用于iOS的ios6 4英寸和3.5英寸屏幕

Question

我正在开发iOS7＆amp; iOS6（3.5英寸和4英寸屏幕）。

• 我在UIView中显示6个按钮。六个按钮分为3行。每两个按钮显示单行。
• 显示的总行数为3.
• 我还在视图的底部集成了iAD。

我的问题是在iOS7 4-inches屏幕显示正确的方式。在具有4英寸屏幕的iOS 6中，它无法正常显示。我有对齐问题。带有3.5英寸的iOS7也出现了一些对齐问题。但是3.5英寸的iOS6显示效果很好。

我不知道如何修复对齐问题。这是我的示例代码：

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

- (void)viewDidLoad

{

[super viewDidLoad];

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))

{

[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault];

naviBarObj=[[UINavigationBar alloc]initWithFrame:CGRectMake(0, 20, 320, 64)];

[self.view addSubview:naviBarObj];

[naviBarObj setBarTintColor:[UIColor colorWithRed:38.0f/255.0f green:45.0f/255.0f blue:51/255.0f alpha:1.0]];

// Weekly Audio Button Creation..

weeklyAudio=[UIButton buttonWithType:UIButtonTypeCustom];

[weeklyAudio addTarget:self action:@selector(weeklyPredictions) forControlEvents:UIControlEventTouchUpInside];

[weeklyAudio setTitle:@"WEEKLY" forState:UIControlStateNormal];

weeklyAudio.titleLabel.textAlignment = NSLineBreakByWordWrapping;

weeklyAudio.titleLabel.numberOfLines = 2;

[weeklyAudio.titleLabel setTextAlignment: NSTextAlignmentCenter];

[weeklyAudio setTitleEdgeInsets:UIEdgeInsetsMake(60, 10, 10, 10)];

[weeklyAudio.titleLabel setFont:[UIFont systemFontOfSize:14.0]];

weeklyAudio.frame=CGRectMake(10, 100, 140, 120);

weeklyAudio.layer.cornerRadius=5;

weeklyAudio.backgroundColor=[UIColor colorWithRed:232.0f/255.0f green:52.0f/255.0f blue:27.0f/255.0f alpha:1.0];

[self.view addSubview:weeklyAudio];

weeklyAudioImage=[[UIImageView alloc]initWithFrame:CGRectMake(45, 10, 48, 48)];

weeklyAudioImage.image=[UIImage imageNamed:@"48*48.png"];

[weeklyAudio addSubview:weeklyAudioImage];

// Create Yearly Audio Button.
