XCode中有LaunchScreen.storyboard或者LaunchScreen.xib疾忍，蘋果默認(rèn)使用的就是拿這個(gè)當(dāng)啟動(dòng)頁(yè)，這是一個(gè)靜態(tài)的頁(yè)面企孩，也就是只能用自動(dòng)布局來(lái)適配屏幕的大小，就一張圖片居中顯示袁稽，這個(gè)兼容性不強(qiáng)勿璃。另外一種方法，這種方法很多人都在用推汽，只要設(shè)置正確 尺寸格式正確就可以正常顯示的补疑。常用的尺寸格式如下：

步驟如下：

1、點(diǎn)擊Image.xcassets 進(jìn)入圖片管理,然后右擊,彈出"New Launch Image"
2歹撒、如圖,右側(cè)的勾選可以讓你選擇是否要對(duì)ipad,橫屏,豎屏,以及低版本的ios系統(tǒng)做支持.這邊我選了ios8.0,ios7.0,ios6沒(méi)有做支持.

3莲组、選擇launchImage

4、清空Launch Screen File

5暖夭、加入版本號(hào)的代碼

#import "AppDelegate.h"
#import "ViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor whiteColor];
    self.window.rootViewController = [[ViewController alloc] init];
    [self.window makeKeyAndVisible];
    
    [self customLaunchImageView];

    return YES;
}
- (void)customLaunchImageView
{
    UIImageView *launchImageView = [[UIImageView alloc] initWithFrame:self.window.bounds];
    launchImageView.image = [self getLaunchImage];
    [self.window addSubview:launchImageView];
    [self.window bringSubviewToFront:launchImageView];
    
    UILabel *vesionLabel = [[UILabel alloc] initWithFrame:CGRectMake(100, 260, 100, 30)];
    vesionLabel.backgroundColor = [UIColor cyanColor];
    //獲取當(dāng)前設(shè)備中應(yīng)用的版本號(hào)
    NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
    NSString *currentVersion = [infoDic objectForKey:@"CFBundleShortVersionString"];
    vesionLabel.text = [NSString stringWithFormat:@"V %@",currentVersion];
    vesionLabel.textAlignment = NSTextAlignmentCenter;
    [launchImageView addSubview:vesionLabel];
    
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.8 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        [UIView animateWithDuration:1.2 animations:^{
            launchImageView.alpha = 0.0;
            launchImageView.transform = CGAffineTransformMakeScale(1.2, 1.2);
        } completion:^(BOOL finished) {
            [launchImageView removeFromSuperview];
        }];
    });
}

- (UIImage *)getLaunchImage
{
    UIImage *lauchImage = nil;
    NSString *viewOrientation = nil;
    CGSize viewSize = [UIScreen mainScreen].bounds.size;
    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    
    if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) {
        
        viewOrientation = @"Landscape";
        
    } else {
        
        viewOrientation = @"Portrait";
    }
    
    NSArray *imagesDictionary = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"UILaunchImages"];
    for (NSDictionary *dict in imagesDictionary) {
        
        CGSize imageSize = CGSizeFromString(dict[@"UILaunchImageSize"]);
        if (CGSizeEqualToSize(imageSize, viewSize) && [viewOrientation isEqualToString:dict[@"UILaunchImageOrientation"]]) {
            
            lauchImage = [UIImage imageNamed:dict[@"UILaunchImageName"]];
        }
    }
    return lauchImage;
}

運(yùn)行結(jié)果：
