zip Build Status

Can get the Image in the zip file which generated from TexturePacker.

Usage :

1. Generated image file by TextPacker, and compressed into a zip.

2. Project put into the zipAndTexure group.And import libz.dylib class library.

3. In the AppDelegate.m import "TexureManager.h", "ZipArchive.h", "UIImage+zipArchiveAndTexure.h", "JRSwizzle.h".And joined the zipfile function (you can see in the project file),The function is as follows (the which demo.zip you compress the file,demo_texture is the TexturePacker generated file name).

static dispatch_once_t once;

dispatch_once(&once, ^{
    NSString *resPath = [[NSBundle mainBundle] pathForResource:@"demo"
                                                        ofType:@"zip"];

    ZipArchive *za = [[ZipArchive alloc] init];

    if ([za UnzipOpenFile:resPath]) { //zip file
        NSArray *paths = 
        NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = paths[0]; //get Documents address

        BOOL ret = [za UnzipFileTo:documentsDirectory overWrite:YES];
        if (YES == ret) {
            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0),
                           ^{
                               NSFileManager *fileManager = [NSFileManager defaultManager];
                               [fileManager removeItemAtPath:resPath error:nil];
                           });
        }
        [za UnzipCloseFile];
    }

    [za release];
    [[TexureManager shareInstance] addTextureFile:@"demo_texture"];
    [self.viewController performSelectorOnMainThread:@selector(zip_Completed)
                                          withObject:nil
                                       waitUntilDone:NO];
});

And then in method

- (BOOL)application:(UIApplication *)application 
willFinishLaunchingWithOptions:(NSDictionary *)launchOptions

add follows:

queue = [[NSOperationQueue alloc] init];
NSInvocationOperation *op = [[[NSInvocationOperation alloc] initWithTarget:self
                                                                  selector:@selector(zipFile)
                                                                    object:nil] autorelease];
[queue addOperation:op];

[UIImage jr_swizzleClassMethod:@selector(imageNamed:)
               withClassMethod:@selector(getImageByName:)
                         error:nil];

4. get Image function as follows:

UIImage * myImg = [UIImage imageNamed:@"UI_FacebookButton.png"];


从zip压缩过的TexturePacker生成的文件取出图片。

用法 :

1. 通过TextPacker生成图片文件,并压缩成zip。
2. 项目中导入zipAndTexure组(黄色文件夹)。并且导入libz.dylib类库。
3. 在程序的AppDelegate.m里引用"TexureManager.h", "ZipArchive.h", "UIImage+zipArchiveAndTexure.h", "JRSwizzle.h"。再加入zipFile函数(项目文件当中有),函数如下(其中demo.zip为你压缩过后的文件,demo_texture为TexturePacker生成文件名):

static dispatch_once_t once;

dispatch_once(&once, ^{
    NSString *resPath = [[NSBundle mainBundle] pathForResource:@"demo"
                                                        ofType:@"zip"];

    ZipArchive *za = [[ZipArchive alloc] init];

    if ([za UnzipOpenFile:resPath]) { //解压
        NSArray *paths = 
        NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = paths[0]; //前两句为获取Documents在真机中的地址

        BOOL ret = [za UnzipFileTo:documentsDirectory overWrite:YES];
        if (YES == ret) {
            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0),
                           ^{
                               NSFileManager *fileManager = [NSFileManager defaultManager];
                               [fileManager removeItemAtPath:resPath error:nil];
                           });
        }
        [za UnzipCloseFile];
    }

    [za release];
    [[TexureManager shareInstance] addTextureFile:@"demo_texture"];
    [self.viewController performSelectorOnMainThread:@selector(zip_Completed)
                                          withObject:nil
                                       waitUntilDone:NO];
});

然后在

- (BOOL)application:(UIApplication *)application 
willFinishLaunchingWithOptions:(NSDictionary *)launchOptions

方法中添加如下代码。

queue = [[NSOperationQueue alloc] init];
NSInvocationOperation *op = [[[NSInvocationOperation alloc] initWithTarget:self
                                                                  selector:@selector(zipFile)
                                                                    object:nil] autorelease];
[queue addOperation:op];

[UIImage jr_swizzleClassMethod:@selector(imageNamed:)
               withClassMethod:@selector(getImageByName:)
                         error:nil];

4. 使用图片函数如下:

UIImage * myImg = [UIImage imageNamed:@"UI_FacebookButton.png"];
