ios 类似于网易的启动页广告

效果图：

1.使用：将广告添加到window上面

 UIWindow *_window = [UIApplication sharedApplication].delegate.window;    [TFLaunchAd showAdAtPath:@"http://img1.126.net/channel6/2015/ad/2_1224a.jpg"         onView:_window                       timeInterval:10                   detailParameters:nil];

2.广告类的源码如下

#import <Foundation/Foundation.h>@import UIKit.UIView;extern NSString *TFLaunchAdDetailDisplayNotification;@interface TFLaunchAd : NSObject+ (void)showAdAtPath:(NSString *)path              onView:(UIView *)container        timeInterval:(NSTimeInterval)interval    detailParameters:(NSDictionary *)param;@end
