如何在同一时间滑动标签文本和图像

Question

我已经在我的应用程序中创建了滑块，我希望图像和标签都是同时滑动的。

此时图像滑块正常工作，但标签滑块不起作用。我想要一个标签文本幻灯片如何工作。请帮忙。谢谢

我的代码

- (void)viewDidLoad { 
[super viewDidLoad]; 

NSURLRequest *req=[[NSURLRequest alloc]initWithURL:[NSURL URLWithString:@"http://edutimeapp.com/toshow/chamber-of-commerc/ws/fetch_event.php"]]; 
response =[[NSMutableData alloc]init]; 
[NSURLConnection connectionWithRequest:req delegate:self]; 
} 

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
{ 
[response appendData:data]; 
NSLog(@"error receving data %@",response); 
} 

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
{ 

} 
-(void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    NSError *error; 

NSLog(@"Error in receiving data %@",error); 
NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error]; 
NSLog(@"response data %@",json); 

NSArray *results = [json objectForKey:@"status"]; 
img_ary =[[results valueForKey:@"slider"]valueForKey:@"imageurl"]; 
NSLog(@"images fetch %@",img_ary); 

des_ary =[[results valueForKey:@"slider"]valueForKey:@"title"]; 
NSLog(@"label text %@",des_ary); 

for (NSString *line in des_ary) { 
    NSLog(@"%@", line); 

    self.label.text=line; 

} 

NSMutableArray *arrayImages = [[NSMutableArray alloc] init]; 

for (NSString *strImageUrl in img_ary) { 
    [arrayImages addObject:[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:strImageUrl]]]]; 
} 

self.img.animationImages = arrayImages; 
_img.animationDuration=10; 
_img.animationRepeatCount = 0; 
[_img startAnimating]; 
} 

标签滑块代码

NSMutableArray *arraylabel = [[NSMutableArray alloc] init]; 

for (NSString *line in des_ary) { 
    NSLog(@"%@", line); 
    [arraylabel addObject:line]; 
    self.label.text=arraylabel; 
    [self.label sizeToFit]; 
    self.label.center = self.view.center; 
    self.label.textAlignment = NSTextAlignmentLeft; 

    [UIView animateWithDuration:0.5 
        animations:^{ 
         CGRect frame = self.label.frame; 
         frame.origin.x = 10; 
         self.label.frame = frame; 
        } completion:nil]; 


}

让globalCounter为全局变量，确保测试数据你

globalCounter=0; 
if(nameArray.count>0){ 

    [self changeLable]; 

} 

然后

-(void)changeLable{ 

    if(!(globalCounter<nameArray.count)){ 
     return; 
    } 


    NSLog(@"globalCounter %d",globalCounter); 

    [UIView animateWithDuration:1 
          delay:0.5 
         options: UIViewAnimationOptionTransitionCrossDissolve 
        animations:^{ 


        } 
        completion:^(BOOL finished) { 

         [lblTitle setText:[nameArray objectAtIndex:globalCounter]]; 
         globalCounter++; 

         [self performSelector:@selector(changeLable) withObject:nil afterDelay:1]; 

        }]; 


}
