兩種方式，一種是使用系統(tǒng)自帶的，按規(guī)則定義啟動圖片名稱即可，顯示為1秒，要想延長時間，用［nsthread
sleepForTimeInterval:5.0］,另一種就是自定義uiivew, 加到window中去?；蛘咦远x一個UIViewController。
1系統(tǒng)自帶方式
1.1 添加圖片
1，準備圖片資源，放入工程中，即可，默認時間為1s
iOS設備現(xiàn)在有三種不同的分辨率：iPhone?320x480、iPhone?4?640x960、iPad?768x1024。以前程序的啟動畫面(圖片)只要準備一個Default.png就可以了，但是現(xiàn)在變得復雜多了。下面就是CocoaChina會員做得總結
如果一個程序，既支持iPhone又支持iPad，那么它需要包含下面幾個圖片：
Default-Portrait.png?iPad專用豎向啟動畫面768x1024或者768x1004
Default-Landscape.png?iPad專用橫向啟動畫面1024x768或者1024x748
Default-PortraitUpsideDown.png?iPad專用豎向啟動畫面(Home按鈕在屏幕上面)，可省略768x1024或者768x1004
Default-LandscapeLeft.png?iPad專用橫向啟動畫面，可省略1024x768或者1024x748
Default-LandscapeRight.png?iPad專用橫向啟動畫面，可省略1024x768或者1024x748
Default.png?iPhone默認啟動圖片，如果沒有提供上面幾個iPad專用啟動圖片，則在iPad上運行時也使用Default.png（不推薦）320x480或者320x460
Default@2x.png?iPhone4啟動圖片640x960或者640x920
為了在iPad上使用上述的啟動畫面，你還需要在info.plist中加入key:?UISupportedInterfaceOrientations。同時，加入值UIInterfaceOrientationPortrait,?UIInterfacOrientationPortraitUpsideDown,?UIInterfaceOrientationLandscapeLeft,?UIInterfaceOrientationLandscapeRight。
1.2延遲時間
2，如果想想設啟動畫面的顯示時間，
在XXXAppDelegate.m的-?(BOOL)application:(UIApplication?*)application?didFinishLaunchingWithOptions:(NSDictionary*)launchOptions方法中插入以下一行代碼:
//?Insert?delay?of?5?seconds?befor?the?splash?screen?disappers.
[NSThread?sleepForTimeInterval:5.0];??//其實這一行代碼也可以不加，因為默認情況下歡迎界面的時間只有一秒，加這一句是為了延長
歡迎界面的展示時間到5秒，時間大家可以自己定義。
1.3啟動時顯示狀態(tài)欄
?在-info.plist文件中加入選項"Status bar is initially
hidden",值為YES
在AppDelegate.m文件中的- (BOOL)application:(UIApplication
*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法內加入代碼：[[UIApplication sharedApplication] setStatusBarHidden:NO];
【注意】
如果你的程序同時使用了導航欄作為根視圖控制器UINavigationController，則應該將語句[[UIApplication sharedApplication] setStatusBarHidden:NO]放在[self.window makeKeyAndVisible];之前，否則會出現(xiàn)狀態(tài)欄與導航欄重疊的情況。可能是因為調用makeKeyAndVisible時會去判斷當前程序是否顯示狀態(tài)欄，以此來布導航欄的位置。
2自定義方法
3，在XXXAppDelegate.m的-?(BOOL)application:(UIApplication?*)application?didFinishLaunchingWithOptions:(NSDictionary*)launchOptions中通過使用uiview或uiimageview等控件自定義啟動畫面
3App圖標添加
The app icon set named "AppIcon" did not have anyapplicable content.
Solution:
icon 的大小注意長寬一樣，不然報錯：The app icon set named "AppIcon" did not have anyapplicable content.

4引導頁開發(fā)
4.1UIScrollview+UIImageView方案
我們在第一次打開App的時候，通常不是直接進入App主界面，而是會有一個能左右滑動、介紹App功能的界面。我是用NSUserDefaults + UIScrollview實現(xiàn)。
新建一個類，繼承UIView，假設名為Guide。在initWithFrame方法里:
CGFloat screenHeight = [UIScreenmainScreen].bounds.size.height;
UIScrollView* scrollView =[[UIScrollView alloc] initWithFrame:frame];
scrollView.backgroundColor =[UIColor whiteColor];
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.contentSize =CGSizeMake(320*4, screenHeight);
scrollView.pagingEnabled = YES;
for (int i=0; i<4; i++) {
UIImageView* imageView =[[UIImageView alloc initWithFrame:CGRectMake(i*320, 0, 320, screenHeight)];
imageView.contentMode =UIViewContentModeScaleAspectFill;
NSString *filePath = [[NSBundlemainBundle] pathForResource:
[NSStringstringWithFormat:@"FileName"
ofType:@"FileType"];
imageView.image = [UIImageimageWithContentsOfFile:filePath];
[scrollView addSubview:imageView];
if (i == 3) {
UIButton* start = [UIButtonbuttonWithType:UIButtonTypeCustom];
start.frame = CGRectMake(0,0,100,44);
start.layer.cornerRadius =5;
start.layer.borderWidth =0.5;
[start setCenter:CGPointMake(1120, iPhone5?450:400)];
[start setTitleColor:[UIColorgrayColor] forState:UIControlStateNormal];
[start addTarget:selfaction:@selector(closeView) forControlEvents:UIControlEventTouchUpInside];
[start setTitle:@"Start"forState:UIControlStateNormal];
[scrollView addSubview:start];
}
這樣，就有了一個有4張圖片的引導頁。
怎么去判斷是不是第一次登陸呢，需要用到NSUserDefaults類。
在didFinishLaunchingWithOptions:函數(shù)中可以這樣判斷：
NSUserDefaults* userDefaults = [NSUserDefaults standardUserDefaults];
if([userDefaults objectForKey:@"FirstLoad"] == nil) {
[userDefaults setBool:NO forKey:@"FirstLoad"];
//顯示引導頁
}

4.3第三方庫MYBlurIntroductionView方案
4.3.1設計思路
新建一個LaunchVC，然后在RootVC中以模態(tài)窗口的方式彈出此VC。引導頁采用本地緩存方式，支持從服務端動態(tài)加載然后更新顯示。
4.3.2LaunchVC彈出邏輯
LaunchVC彈出邏輯（注意只加載一次）：
if(![MDUtilityhasLoadLaunchView]) {
_launchVC= [[MDLaunchViewControlleralloc]init];
[self.navigationControllerpresentViewController:_launchVCanimated:NOcompletion:nil];
}
4.3.3LaunchVC初始化邏輯
LaunchVC初始化邏輯：
- (void)viewDidLoad {
[superviewDidLoad];
[selfinitSubViews];
// Do
any additional setup after loading the view.
}
-(void) initSubViews
{
if(!_introductView) {
[selfinitIntroductView];
}
}
-(void)initIntroductView
{
NSArray*launchImgFileArr = [MDUtilitygetLaunchImgFilePathArr];
if([launchImgFileArrcount] <=0) {
return;
}
//動態(tài)加載引導頁圖片
NSMutableArray*panelMArr = [[NSMutableArrayalloc]init];
for(NSString*imgFileinlaunchImgFileArr) {
//Create Stock Panel With Image
//MYIntroductionPanel*launchView = [[MYIntroductionPanel alloc] initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height) title:nildescription:nil image:[UIImage imageWithContentsOfFile:imgFile]];
MDLaunchView*launchView = [[MDLaunchViewalloc]initWithFrame:CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)WithbackImg:[UIImageimageWithContentsOfFile:imgFile]];
[panelMArraddObject:launchView];
}
//Create
the introduction view and set its delegate
MYBlurIntroductionView*introductionView = [[MYBlurIntroductionViewalloc]initWithFrame:CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)];
introductionView.delegate=self;
//introductionView.BackgroundImageView =[UIImage imageNamed:@"Toronto, ON.jpg"];
//introductionView.LanguageDirection
= MYLanguageDirectionRightToLeft;
_introductView= introductionView;
//Build
the introduction with desired panels
[introductionViewbuildIntroductionWithPanels:panelMArr];
//Add
the introduction to your view
[self.viewaddSubview:introductionView];
}
4.3.4本地緩存引導圖片邏輯
+(BOOL)hasLoadLaunchView
{
BOOLloaded = [[[NSUserDefaultsstandardUserDefaults]valueForKey:kHasLoadLaunchView]boolValue];
returnloaded;
}
//刷新本地緩存的引導頁圖片數(shù)據(jù)
+ (void)loadLaunchImgData
{
//獲取Documents目錄路徑
NSArray*paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString*docDir
= [pathsobjectAtIndex:0];
NSString*launchDir = [docDirstringByAppendingString:@"/LaunchImg"];
NSFileManager*
fm=[NSFileManagerdefaultManager];
//NSString *imagePath = [[NSBundlemainBundle] pathForResource:@"22" ofType:@"jpg"];
if(![fmfileExistsAtPath:launchDir]){
NSError*error =nil;
//下面是對該文件進行制定路徑的保存
[fmcreateDirectoryAtPath:launchDirwithIntermediateDirectories:YESattributes:nilerror:nil];
NSString*sourcePath = [[NSBundlemainBundle]pathForResource:@"1"ofType:@"jpg"];
NSString*toPath = [launchDirstringByAppendingString:@"/1.jpg"];
[fmcopyItemAtPath:sourcePathtoPath:toPatherror:&error];
if(error) {
return;
}
//[[self class] copyFile:sourcePathTo:toPath];
sourcePath = [[NSBundlemainBundle]pathForResource:@"2"ofType:@"jpg"];
toPath = [launchDirstringByAppendingString:@"/2.jpg"];
[fmcopyItemAtPath:sourcePathtoPath:toPatherror:&error];
if(error) {
return;
}
sourcePath = [[NSBundlemainBundle]pathForResource:@"3"ofType:@"jpg"];
toPath = [launchDirstringByAppendingString:@"/3.jpg"];
[fmcopyItemAtPath:sourcePathtoPath:toPatherror:&error];
if(error) {
return;
}
sourcePath = [[NSBundlemainBundle]pathForResource:@"4"ofType:@"jpg"];
toPath = [launchDirstringByAppendingString:@"/4.jpg"];
[fmcopyItemAtPath:sourcePathtoPath:toPatherror:&error];
if(error) {
return;
}
[[NSUserDefaultsstandardUserDefaults]setValue:[NSNumbernumberWithBool:NO]forKey:kHasLoadLaunchView];
}
else
{
[[NSUserDefaultsstandardUserDefaults]setValue:[NSNumbernumberWithBool:YES]forKey:kHasLoadLaunchView];
///TODO:后續(xù)在此進行網絡請求，刪除本地文件，然后更新本地文件,然后重置kHasLoadLaunchView值為NO
}
}
+(NSArray*)getLaunchImgFilePathArr
{
NSArray*paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString*docDir = [pathsobjectAtIndex:0];
NSString*launchDir = [docDirstringByAppendingString:@"/LaunchImg"];
NSFileManager*
fm=[NSFileManagerdefaultManager];
//取得一個目錄下得所有文件名
NSArray*files = [fmsubpathsAtPath:launchDir];
if([filescount] >0) {
NSMutableArray*filePathArr = [[NSMutableArrayalloc]init];
for(NSString*fpinfiles) {
[filePathArraddObject:[launchDirstringByAppendingString:[NSStringstringWithFormat:@"/%@",fp]]];
}
returnfilePathArr;
}
else
returnnil;
}
5半透明遮罩
5.1法一
我最后采取的方法，是present一個窗口化的ViewController。但是這個窗口默認的背景色是磨砂不透明的，因此還需要把它的背景色設為透明。這樣看起來就像是全屏遮罩一樣，但是由于系統(tǒng)不認為新的View是全屏的，所以上一個View也不會被unload。
YLSLockScreenViewController*lockScreenController = [[YLSLockScreenViewController alloc] init];
lockScreenController.modalPresentationStyle
= UIModalPresentationFormSheet;//窗口
[self.mainViewControllerpresentViewController:lockScreenController animated:YES completion:^(void){
lockScreenController.view.superview.backgroundColor = [UIColorclearColor];//背景色透明
}];
代碼比較簡單，需要注意的是，設置背景色透明的那行代碼，需要寫在completion block里，而且設置的不是controller.view.backgroundColor，而是controller.view.superview.backgroundColor。

5.2法二(good)
backgroundView = [[UIView alloc] init];
backgroundView.frame= CGRectMake(0, 0,kWidth,kHeight);
backgroundView.backgroundColor= [UIColor colorWithRed:(40/255.0f) green:(40/255.0f) blue:(40/255.0f)alpha:1.0f];
backgroundView.alpha= 0.4;
[self.view.windowaddSubview:backgroundView];
