My question is what format the image is saved, if is dat or jpg. This is the code that i used:
NSString * urlImage = .....;
NSString * _folderPath = .....;
NSString * imageName = [[urlImage componentsSeparatedByString:@"/"] lastObject];
NSString * jpegPath = [NSString stringWithFormat:@"%@%@",_folderPath,imageName];
if (![[NSFileManager defaultManager] fileExistsAtPath:jpegPath])
{
NSURL *url = [NSURL URLWithString:urlImage];
//Download image
UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:url]];
//Save image
NSData *data = [NSData dataWithData:UIImageJPEGRepresentation(image, 1.0f)];//1.0f = 100% quality
[data writeToFile:jpegPath atomically:YES];
}
Following is piece of code for save .jpg image
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *docs = [paths objectAtIndex:0];
NSString* path = [docs stringByAppendingFormat:@"/image1.jpg"];
NSData* imageData = [NSData dataWithData:UIImageJPEGRepresentation(imageView.image, 80)];
NSError *writeError = nil;
[imageData writeToFile:path options:NSDataWritingAtomic error:&writeError];
You should use
stringByAppendingPathComponent
method to create or get exact valid path
Use this way:
NSString * jpegPath = [_folderPath stringByAppendingPathComponent:imageName];// [NSString stringWithFormat:@"%@%@",_folderPath,imageName];
