iOS 视图滑动与轮播图的问题

@interface ViewController ()<UITableViewDataSource, UITableViewDelegate>

@property (nonatomic , retain)UILabel *lable;

 

@end

 

@implementation ViewController

int a ;

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    

    UITableView *table = [[UITableView alloc]initWithFrame:self.view.bounds];

    table.delegate = self;

    table.dataSource = self;

    

    [self.view addSubview:table];

    

    [table registerClass:[UITableViewCell class] forCellReuseIdentifier:@"cell"];

    

    self.view.backgroundColor = [UIColor redColor];

    //如果滑动 timer 停止

//    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timeIntervalSinceNow:) userInfo:nil repeats:YES];

    //将 timer 添加到 Runloop 中  解决了滑动timer停止

    NSTimer *timer = [NSTimer timerWithTimeInterval:1 target:self selector:@selector(timeIntervalSinceNow:) userInfo:nil repeats:YES];

    

    [[NSRunLoop currentRunLoop] addTimer:timer forMode:NSRunLoopCommonModes];

    

    

    self.lable = [[UILabel alloc]initWithFrame:CGRectMake(10, 100, 300, 100)];

    _lable.backgroundColor = [UIColor yellowColor];

    //    _lable.text = @"hahhahaa ";

  //Xcode 7.1 之后 , window 在viewDidLoad中获取, 然后加载视图,是被覆盖到self.view下的, 解决方法 : 在 viewDidAppear 里获取 window

//    UIWindow *window = [UIApplication sharedApplication].windows.firstObject;

//    

//    //    UIWindow *app = [UIApplication sharedApplication];

//    

//    [window addSubview:_lable];

}

 

- (void)viewDidAppear:(BOOL)animated

{

    self.lable = [[UILabel alloc]initWithFrame:CGRectMake(10, 100, 300, 100)];

    _lable.backgroundColor = [UIColor yellowColor];

//    _lable.text = @"hahhahaa ";

    

    UIWindow *app = [UIApplication sharedApplication].windows.firstObject;

    

    //    UIWindow *app = [UIApplication sharedApplication];

    

    [app addSubview:_lable];

}

 

- (void)timeIntervalSinceNow : (NSTimer *)time

{

    self.lable.text =[NSString stringWithFormat:@"%d",a++];

    NSLog(@"%@" , time);

}

 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

    return 10;

}

 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];

    return cell;

}
