一靠欢、AppDelegate.m里面引入類(lèi)ViewController.h然后設(shè)置首頁(yè)面
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
? ? ? ? self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
? ? ? ? ViewController *mainVC=[[ViewController alloc]init];
? ? ? ? ?UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:mainVC];
? ? ? ? ?self.window.rootViewController = nav;
? ? ? ? ?[self.window makeKeyAndVisible];
? ? ? ? return YES;
}
二门扇、新建FlashPageView類(lèi)繼承UIView揽思，用來(lái)設(shè)置啟動(dòng)頁(yè)
1炮温、FlashPageView.h
#define kscreenWidth [UIScreen mainScreen].bounds.size.width
#define kscreenHeight [UIScreen mainScreen].bounds.size.height
#import ?<UIKit/UIKit.h>
typedef void (^PushToAdBlock)(void);
@interface FlashPageView : UIView
@property (nonatomic, strong) UIImageView *adView;/** 圖片*/
@property (nonatomic, copy) NSString *filePath;/** 圖片路徑*/
@property (nonatomic,copy) PushToAdBlock ?pushToAdBlock;
- (void)show;/** 顯示啟動(dòng)頁(yè)面方法*/
-(void) TouchPushToAdBlock:(PushToAdBlock)pushToAdBlock;
@end
2横侦、FlashPageView.m
#import "FlashPageView.h"
@interface FlashPageView ()
@property (nonatomic, strong) UIButton *countBtn; ?/**倒計(jì)時(shí)按鈕*/
@property (nonatomic, strong) NSTimer *countTimer;?/**定時(shí)器*/
@property (nonatomic, assign) int count; ?/**倒計(jì)時(shí)*/
@end
static int const showtime = 10; ?// 啟動(dòng)頁(yè)顯示的時(shí)間
@implementation?FlashPageView
- (instancetype)initWithFrame:(CGRect)frame{
? ? ? ? if (self = [super initWithFrame:frame]) {
? ? ? ? // 1.閃頻頁(yè)圖片
? ? ? ? _adView = [[UIImageView alloc] initWithFrame:frame];
? ? ? ?_adView.image = [UIImage imageNamed:@"啟動(dòng)頁(yè)"];
? ? ? ?_adView.userInteractionEnabled = YES;//用戶交互
? ? ? ?_adView.contentMode = UIViewContentModeScaleAspectFill;//?等比例縮放至父容器完全裝下圖片為止.圖片沒(méi)有變形
? ? ? ? _adView.clipsToBounds = YES;
? ? ? ? ?UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(pushToAd)]; ?//利用手勢(shì)給控件添加點(diǎn)擊事件
? ? ? ? [_adView addGestureRecognizer:tap];
? ? ? ? // 2.跳過(guò)按鈕
? ? ? ? CGFloat btnW = 60;
? ? ? ? CGFloat btnH = 30;
? ? ? ? _countBtn = [[UIButton alloc] initWithFrame:CGRectMake(kscreenWidth - btnW - 24, btnH, btnW, btnH)];
? ? ? ? [_countBtn addTarget:self action:@selector(dismiss) forControlEvents:UIControlEventTouchUpInside];
? ? ? ? [_countBtn setTitle:[NSString stringWithFormat:@"跳過(guò)%d", showtime] forState:UIControlStateNormal];
? ? ? ? _countBtn.titleLabel.font = [UIFont systemFontOfSize:15];
? ? ? ? [_countBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
? ? ? ? _countBtn.backgroundColor = [UIColor colorWithRed:38 /255.0 green:38 /255.0 blue:38 /255.0 alpha:0.6];
? ? ? ? ?_countBtn.layer.cornerRadius = 4;
? ? ? ? ?[_countBtn addTarget:self action:@selector(countBtnClick) forControlEvents:UIControlEventTouchUpInside];
? ? ? ? ?[self addSubview:_adView];
? ? ? ? ?[self addSubview:_countBtn];
? ? ? ? }
? ? ? ? return self;
}
- (NSTimer *)countTimer{
? ? ? ? ? if (!_countTimer) {
? ? ? ? ? ? ? ? ? ?_countTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countDown) userInfo:nil repeats:YES];
? ? ? ? ?}
? ? ? ? ?return _countTimer;
}
-(void)countBtnClick{
? ? ? ? ?[self dismiss];
}
- (void)setFilePath:(NSString *)filePath{
? ? ? ? _filePath = filePath;
? ? ? ?_adView.image = [UIImage imageWithContentsOfFile:filePath];
}
- (void)pushToAd{
? ? ? ?NSLog(@"點(diǎn)擊圖片");
? ? ? ? __weak typeof(self) WeakSelf = self;
? ? ? ?if (WeakSelf.pushToAdBlock) {
? ? ? ? ? ? ? ?WeakSelf.pushToAdBlock();
? ? ? ? }
? ? ? ? ?[self dismiss];
}
-(void) TouchPushToAdBlock:(PushToAdBlock)pushToAdBlock{
? ? ? ? ?self.pushToAdBlock = pushToAdBlock;
}
- (void)countDown{
? ? ? ? ?_count --;
? ? ? ? ?[_countBtn setTitle:[NSString stringWithFormat:@"跳過(guò)%d",_count] forState:UIControlStateNormal];
? ? ? ? if (_count == 0) {
? ? ? ? ? ? ? ? [self.countTimer invalidate];
? ? ? ? ? ? ? ? self.countTimer = nil;
? ? ? ? ? ? ? ? [self dismiss];
? ? ? ? ? }
}
- (void)show{
? ? ? ? ? ? // 倒計(jì)時(shí)方法1：GCD
? ? ? ? ? ? //? ? [self startCoundown];
? ? ? ? ? ? // 倒計(jì)時(shí)方法2：定時(shí)器
? ? ? ? ? ? ? [self startTimer];
? ? ? ? ? ? ? UIWindow *window = [UIApplication sharedApplication].keyWindow;
? ? ? ? ? ? ?[window addSubview:self];
}
// 定時(shí)器倒計(jì)時(shí)
- (void)startTimer{
? ? ? ? ? ?_count = showtime;
? ? ? ? ? ?[[NSRunLoop mainRunLoop] addTimer:self.countTimer forMode:NSRunLoopCommonModes];//定時(shí)器只運(yùn)行在NSDefaultRunLoopMode下彻犁，一旦RunLoop進(jìn)入其他模式局待，這個(gè)定時(shí)器就不會(huì)工作斑响，該模式表示在沒(méi)有輸入源的情況下
}
//// GCD多線程倒計(jì)時(shí)
//- (void)startCoundown{
//? ? __block int timeout = showtime + 1; //倒計(jì)時(shí)時(shí)間 + 1
//? ? dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
//? ? dispatch_source_t _timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER, 0, 0,queue);
//? ? dispatch_source_set_timer(_timer,dispatch_walltime(NULL, 0),1.0 * NSEC_PER_SEC, 0); //每秒執(zhí)行
//? ? dispatch_source_set_event_handler(_timer, ^{
// ? ?if(timeout <= 0){ //倒計(jì)時(shí)結(jié)束，關(guān)閉
//? ? ? ? ? ? dispatch_source_cancel(_timer);
//? ? ? ? ? ? dispatch_async(dispatch_get_main_queue(), ^{
//? ? ? ? ? ? ? ? [self dismiss];
//? ? ? ? ? ? });
//? ? ? ? }else{
//? ? ? ? ? ? dispatch_async(dispatch_get_main_queue(), ^{
// ? ? ? ? ? ? ?[_countBtn setTitle:[NSString stringWithFormat:@"跳過(guò)%d",timeout] forState:UIControlStateNormal];
//? ? ? ? ? ? });
//? ? ? ? ? ? timeout--;
//? ? ? ? }
//? ? });
//? ? dispatch_resume(_timer);
//}
// 移除閃頻頁(yè)面
- (void)dismiss{
? ? ? ? ? ? [UIImageView animateWithDuration:2.0 animations:^{
? ? ? ? ? ? ? ? ? ? ?self.adView.alpha = 0;
? ? ? ? ? ? ? ? ? ? ?[_countBtn removeFromSuperview];
? ? ? ? ? ? ? ? ? ? ?[self.adView removeFromSuperview];
? ? ? ? ? ? } completion:^(BOOL finished) {
? ? ? ? ? ? ? ? ? ? [self removeFromSuperview];
? ? ? ? ? ? }];
}
三钳榨、在ViewController.m里面引入類(lèi)FlashPageView.h然后調(diào)用方法
- (void)viewDidLoad {
? ? ? ? ? ? [super viewDidLoad];
? ? ? ? ? ? self.view.backgroundColor = [UIColor whiteColor];
? ? ? ? ? ? self.title = @"首頁(yè)";
? ? ? ? ? ? FlashPageView *flashPage?= [[FlashPageView alloc]initWithFrame:self.view.bounds];
? ? ? ? ? ? [flashPage show];
}
