IPhone圖片庫源代碼

Question

HI全部 任何人都可以請參考我的iphone圖庫源代碼？ 任何鏈接，示例代碼將非常有幫助。

我想顯示一些70至100的圖像作爲縮略圖，並選擇任何圖像，它應該給出該圖像的完整視圖，我試圖完成，無論是在iphone的圖片庫， 我想，必須有任何示例代碼可用。 建議總是理解

問候

Answer 1

在didload方法調用兩種方法來創建滾動視圖和縮略圖button.Keep兩個縮略圖圖像並以相同的順序牆紙圖像陣列。

-(void)createScrollView 
{ 
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 440)]; 
scrollView.pagingEnabled = YES; 
scrollView.showsHorizontalScrollIndicator = NO; 
scrollView.showsVerticalScrollIndicator = NO; 
scrollView.scrollsToTop = NO; 
scrollView.delegate = self; 
scrollView.contentSize = CGSizeMake(320 * (([imagesArray count]- 1)/25 + 1), 440); 

scrollView.backgroundColor=[UIColor blackColor]; 
[self.view addSubview:scrollView]; 

} 

-(void)createButton{ 
for (int i = 0; i < [imagesArray count]; i++) 
{ 

    thumbNailButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    thumbNailButton.frame = CGRectMake(6 + 62 * (i % 5) + 320 * (i/25), 5+65 * ((i/5) % 5), 56,56); 

    img = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 56, 56)]; 
    [img setImage:[UIImage imageNamed:[imagesArray objectAtIndex:i]]]; 
    thumbNailButton.tag=i; 
    [thumbNailButton addTarget:self action:@selector(imageClicked:) forControlEvents:UIControlEventTouchUpInside]; 
    [thumbNailButton addSubview:img]; 
    [scrollView addSubview:thumbNailButton]; 

} 

} 

-(void)imageClicked:(id)sender{ 
UIButton* button = (UIButton*)sender; 
    AppDelegate *appDelegate=(AppDelegate *)[[UIApplication sharedApplication]delegate]; 
[appDelegate setimageClickedValue:button.tag]; 

LargeWallPaperviewController *largeWallPaperViewController=[[LargeWallPaperviewController alloc]initWithNibName:@"LargeWallPaperviewController" bundle:nil]; 
[self.navigationController pushViewController:largeWallPaperViewController animated:YES]; 
[largeWallPaperViewController release]; 
} 

在didload方法largewallpaperviewcontroller類

[imagesArray addObjectsFromArray:[NSArray arrayWithObjects:@"wallf1.jpg",@"wallf2.jpg",@"wallf3.jpg",@"wallf4.jpg",@"wallf5.jpg",@"wallf6.jpg",@"wallf7.jpg",nil]]; 

scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 440)]; 
scrollView.pagingEnabled = YES; 
scrollView.showsHorizontalScrollIndicator = NO; 
scrollView.showsVerticalScrollIndicator = NO; 
scrollView.scrollsToTop = NO; 
scrollView.delegate = self; 
scrollView.contentSize = CGSizeMake(320 * ([imagesArray count]), 440); 
scrollView.backgroundColor = [UIColor blackColor]; 
[self.view addSubview:scrollView]; 

for (int i = 0; i < [imagesArray count]; i++) 
{ 

    wallPaperButton=[UIButton buttonWithType:UIButtonTypeCustom]; 
    wallPaperButton.tag=i; 
    wallPaperButton.frame=CGRectMake((320*i),0, 320, 325); 

    UIImageView *img =[ [UIImageView alloc]initWithFrame:CGRectMake(0,0, 320, 325)]; 

    img.image=[UIImage imageNamed:[imagesArray objectAtIndex:i]]; 
    img.contentMode=UIViewContentModeScaleAspectFit;    
    [wallPaperButton addSubview:img]; 
    [img release]; 


    [wallPaperButton addTarget:self action:@selector(imageSelected:) forControlEvents:UIControlEventTouchUpInside];  [scrollView addSubview:wallPaperButton]; 
} 
appDelegate=(AppDelegate *)[[UIApplication sharedApplication]delegate]; 
int imageValue=[appDelegate getimageClickedValue]; 
[scrollView scrollRectToVisible:CGRectMake(320*imageValue, 0, 320 , 440) animated:NO]; 

我已經在largewallpaer使用的按鈕view.If你希望你刪除它，並直接將其添加到圖像view.This代碼爲我工作，將其更改爲您的要求。它易於理解。

一切順利。

Answer 2

關閉此代碼。這工作完美。自從我使用故事板以來，我修改了「appdelegate部分」。

這裏是我做的，而不是應用程序委託我只是用

-(void)imageClicked:(id)sender{ 
    UIButton* button = (UIButton*)sender; 
    imageNumber = button.tag; 
    [self performSegueWithIdentifier:@"loadImage" sender:sender]; 


-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{ 
if ([segue.identifier isEqualToString:@"loadImage"]) 
{ 

    [segue.destinationViewController setimageValue:imageNumber]; 
} 
} 

而且在我的目的地View Controller.m文件命名爲'ImageViewController'我實現的事情如下

-(void)setimageValue:(int)number; 
{ 
    self.imageValue = number; 
} 

而且在viewDidLoad，

[self.scrollView scrollRectToVisible:CGRectMake(320*self.imageValue, 0, 320 , 440)   animated:NO];
