一、AppDelegate.m里面引入类ViewController.h然后设置首页面
- (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、新建FlashPageView类继承UIView，用来设置启动页
1、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;/** 图片*/
@property (nonatomic, copy) NSString *filePath;/** 图片路径*/
@property (nonatomic,copy) PushToAdBlock pushToAdBlock;
- (void)show;/** 显示启动页面方法*/
-(void) TouchPushToAdBlock:(PushToAdBlock)pushToAdBlock;
@end
2、FlashPageView.m
#import "FlashPageView.h"
@interface FlashPageView ()
@property (nonatomic, strong) UIButton *countBtn; /**倒计时按钮*/
@property (nonatomic, strong) NSTimer *countTimer; /**定时器*/
@property (nonatomic, assign) int count; /**倒计时*/
@end
static int const showtime = 10; // 启动页显示的时间
@implementation FlashPageView
- (instancetype)initWithFrame:(CGRect)frame{
if (self = [super initWithFrame:frame]) {
// 1.闪频页图片
_adView = [[UIImageView alloc] initWithFrame:frame];
_adView.image = [UIImage imageNamed:@"启动页"];
_adView.userInteractionEnabled = YES;//用户交互
_adView.contentMode = UIViewContentModeScaleAspectFill;// 等比例缩放至父容器完全装下图片为止.图片没有变形
_adView.clipsToBounds = YES;
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(pushToAd)]; //利用手势给控件添加点击事件
[_adView addGestureRecognizer:tap];
// 2.跳过按钮
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:@"跳过%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(@"点击图片");
__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:@"跳过%d",_count] forState:UIControlStateNormal];
if (_count == 0) {
[self.countTimer invalidate];
self.countTimer = nil;
[self dismiss];
}
}
- (void)show{
// 倒计时方法1：GCD
// [self startCoundown];
// 倒计时方法2：定时器
[self startTimer];
UIWindow *window = [UIApplication sharedApplication].keyWindow;
[window addSubview:self];
}
// 定时器倒计时
- (void)startTimer{
_count = showtime;
[[NSRunLoop mainRunLoop] addTimer:self.countTimer forMode:NSRunLoopCommonModes];//定时器只运行在NSDefaultRunLoopMode下，一旦RunLoop进入其他模式，这个定时器就不会工作，该模式表示在没有输入源的情况下
}
//// GCD多线程倒计时
//- (void)startCoundown{
// __block int timeout = showtime + 1; //倒计时时间 + 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); //每秒执行
// dispatch_source_set_event_handler(_timer, ^{
// if(timeout <= 0){ //倒计时结束，关闭
// dispatch_source_cancel(_timer);
// dispatch_async(dispatch_get_main_queue(), ^{
// [self dismiss];
// });
// }else{
// dispatch_async(dispatch_get_main_queue(), ^{
// [_countBtn setTitle:[NSString stringWithFormat:@"跳过%d",timeout] forState:UIControlStateNormal];
// });
// timeout--;
// }
// });
// dispatch_resume(_timer);
//}
// 移除闪频页面
- (void)dismiss{
[UIImageView animateWithDuration:2.0 animations:^{
self.adView.alpha = 0;
[_countBtn removeFromSuperview];
[self.adView removeFromSuperview];
} completion:^(BOOL finished) {
[self removeFromSuperview];
}];
}
三、在ViewController.m里面引入类FlashPageView.h然后调用方法
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
self.title = @"首页";
FlashPageView *flashPage = [[FlashPageView alloc]initWithFrame:self.view.bounds];
[flashPage show];
}
