沙盒路径与文件写入沙盒路径与文件写入

//获取沙盒根目录 NSString *directory = NSHomeDirectory(); NSLog(@"directory:%@", directory);

//获取Documents路径 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *path = [paths objectAtIndex:0]; NSLog(@"path:%@", path);

//获取Library路径 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES); NSString *path = [paths objectAtIndex:0]; NSLog(@"path：%@", path);

//获取Caches路径 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *path = [paths objectAtIndex:0]; NSLog(@"path：%@", path);

NSString *tmp = NSTemporaryDirectory(); NSLog(@"tmp：%@", tmp);

UIImage *image = [UIImage imageNamed:@"flower.png"]; NSString *path_sandox = NSHomeDirectory(); //设置一个图片的存储路径 NSString *imagePath = [path_sandox stringByAppendingString:@"/Documents/flower.png"]; //把图片直接保存到指定的路径（同时应该把图片的路径imagePath存起来，下次就可以直接用来取） [UIImagePNGRepresentation(image)writeToFile:imagePath atomically:YES];
