1.使用SSZipArchive
pod 'SSZipArchive' #zip解压压缩
2.拷贝文件到沙盒
+(BOOL) copyFileToDocument:(NSString*)FileName {
NSString *appFileName =[self fullpathOfFilename:FileName];
NSFileManager *fm = [NSFileManager defaultManager];
//判断沙盒下是否存在
BOOL isExist = [fm fileExistsAtPath:appFileName];
if (!isExist) //不存在，把工程的文件复制document目录下
{
//获取工程中文件
NSString *backupDbPath = [[NSBundle mainBundle]
pathForResource:FileName
ofType:@""];
//这一步实现数据库的添加，
// 通过NSFileManager 对象的复制属性，把工程中数据库的路径复制到应用程序的路径上
[fm copyItemAtPath:backupDbPath toPath:appFileName error:nil];
return isExist;
} else {
return isExist; //已经存在
}
}
3.路径相关
+(NSString *)documentsPath {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
return [paths objectAtIndex:0];
}
+ (NSString *)emojiPathWithName:(NSString *)name {
NSString *path = [NSString stringWithFormat:@"%@/Emotions/%@",[self documentsPath],name];
return path;
}
+ (NSString *)emojiPath {
NSString *path = [NSString stringWithFormat:@"%@/Emotions",[self documentsPath]];
return path;
}
+ (NSArray *)enumeratorListWithEmojiPath {
NSString *path = [self emojiPath]; // 要列出来的目录
NSFileManager *myFileManager=[NSFileManager defaultManager];
NSDirectoryEnumerator *myDirectoryEnumerator;
myDirectoryEnumerator=[myFileManager enumeratorAtPath:path];
//列举目录内容，可以遍历子目录
NSLog(@"用enumeratorAtPath:显示目录%@的内容：",path);
NSMutableArray *array = [NSMutableArray array];
while((path=[myDirectoryEnumerator nextObject])!=nil)
{
if (![path containsString:@"/"] && ![path containsString:@"qq"]) {
[array addObject:path];
NSLog(@"%@",path);
}
}
return array;
}
