首先让我说，我所知道的内容是苹果不赞同的，如果提交，将被App Store拒绝。这不是问题，因为无论如何都不会提交。这是一个内部应用程序。
现在就开始了。我需要一些帮助来设置if，else和else if语句。在迁移到iPhone 6和6+之前，我的当前代码适用于iPhone5 / 5s和低于屏幕尺寸的加载并在应用程序启动后发送正确的图像。
我的目标是将iPhone 6/6 +纳入此等式。
以下是与此相关的相关代码。
这会将图像加载到适当的屏幕尺寸。
//Setting Splash Images
#define IS_IPHONE (!IS_IPAD)
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPhone)
bool isiPhone5 = CGSizeEqualToSize([[UIScreen mainScreen] preferredMode].size,CGSizeMake(640, 1136));
if (isiPhone5) {
// Load iPhone 5 Splash
UIImage *splash4Inch = [UIImage imageNamed:@"Default-568h@2x.png"];
self.splash4InchPortrait = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 568.0f)];
[self.splash4InchPortrait setImage:splash4Inch];
[self.view addSubview:self.splash4InchPortrait];
[self.view bringSubviewToFront:self.splash4InchPortrait];
self.splash4InchPortrait.contentMode = UIViewContentModeScaleToFill;
}
else if (IS_IPAD) {
// Load IPad Splash
UIImage *splashPad = [UIImage imageNamed:@"Default-Portrait~ipad.png"];
self.splashPadPortrait = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 768.0f, 1024.0f)];
[self.splashPadPortrait setImage:splashPad];
[self.view addSubview:self.splashPadPortrait];
[self.view bringSubviewToFront:self.splashPadPortrait];
self.splashPadPortrait.contentMode = UIViewContentModeScaleToFill;
}
else {
// Load the iPhone 3.5" Splash
UIImage *splash35Inch = [UIImage imageNamed:@"Default.png"];
self.splash35InchPortrait = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)];
[self.splash35InchPortrait setImage:splash35Inch];
[self.view addSubview:self.splash35InchPortrait];
[self.view bringSubviewToFront:self.splash35InchPortrait];
self.splash35InchPortrait.contentMode = UIViewContentModeScaleToFill;
}
根据加载的屏幕尺寸隐藏/取消隐藏所述图像。
//Get screen size
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (UIDeviceOrientationIsPortrait(self.interfaceOrientation)){
//DO Portrait
if (screenBounds.size.height <=480) {
//code for 3.5-inch screen
splash35InchPortrait.hidden = NO;
splashRetina35InchPortrait.hidden = YES;
splash4InchPortrait.hidden = YES;
}else{
// code for 3.5 Retina inch screen
splashRetina35InchPortrait.hidden = NO;
}
}else{
// code for 4-inch screen
splash35InchPortrait.hidden = YES;
splashRetina35InchPortrait.hidden = YES;
splash4InchPortrait.hidden = NO;
}
这是完成代码，因为图像渐渐淡出。
- (void)webViewDidFinishLoad:(UIWebView *)webview {
#define IS_IPHONE (!IS_IPAD)
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPhone)
bool isiPhone5 = CGSizeEqualToSize([[UIScreen mainScreen] preferredMode].size,CGSizeMake(640, 1136));
if (isiPhone5) {
// Loading iPhone 5
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"didFinish: %@; stillLoading:%@", [[webView request]URL],
(webView.loading?@"NO":@"YES"));
}
else if (IS_IPAD) {
// Loading IPAD
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"didFinish: %@; stillLoading:%@", [[webView request]URL],
(webView.loading?@"NO":@"YES"));
}
else {
// Loading iPhone 3.5"
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"didFinish: %@; stillLoading:%@", [[webView request]URL],
(webView.loading?@"NO":@"YES"));
}
}
正如你所看到的，我尽我所能地努力工作。我需要添加6/6 +代码。
或者，如果有人知道这样做的更简单的方法，那我就是全部。
主要目标是在应用加载后防止白色闪烁。我试过推迟启动，但由于我的应用程序主要是webview，它根本没有帮助。
感谢阅读和帮助。
答案 0 :(得分：0)
好的，回过头来看看。我拥有我想要的一切。延迟消失，添加所有图像，甚至设法删除调用这些图像的专用视图控制器。没有笔尖，笔记本或故事板。
我的应用程序现在如何设置。我有一个左侧抽屉，如果我按下一个单元格，它会加载该视图但是再次调用闪屏。不理想。但现在它很完美。
这就是我的所作所为。
在我的AppDelegate中：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Removing splash screen user default on app launch
[[NSUserDefaults standardUserDefaults] setObject:@"" forKey:@"Splash"];
[self.window setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
[self.window setBackgroundColor:[UIColor clearColor]];
[self.window makeKeyAndVisible];
return YES;
}
查看控制器：
- (void)viewDidLoad {
[super viewDidLoad];
//Splash Screen View Controller defaults
if (![@"1" isEqualToString:[[NSUserDefaults standardUserDefaults] objectForKey:@"Splash"]]) {
[[NSUserDefaults standardUserDefaults] setValue:@"1" forKey:@"Splash"];
[[NSUserDefaults standardUserDefaults] synchronize];
self.splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[self.view setCenter:CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2)];
[(UIImageView*)splashView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[self.splashView setContentMode:UIViewContentModeScaleToFill];
[self.splashView setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
[self.splashView setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:splashView];
}

非常确定这一切。希望这有助于某人面临类似的问题。
