1、保存至App文件中
首先在项目中创建图片文件夹（相册）
NSFileManager*fileManager = [NSFileManagerdefaultManager];
NSString*filePath = [JGManagerToolimagePath];
[fileManagercreateDirectoryAtPath:filePathwithIntermediateDirectories:YESattributes:nilerror:nil];
- (UIImage*)imageAddImage {
UIImage*logoimage = [UIImageimageNamed:@"水印"];
UIGraphicsBeginImageContext(CGSizeMake(self.image.size.width,self.image.size.height));
CGRectimageRect =CGRectMake(0,0,self.image.size.width,self.image.size.height);
[logoimagedrawInRect:imageRect];
UIImage*newImage =UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImage*targetImage = [[UIImagealloc]init];
targetImage = [targetImageimageWithLogoImage:self.imagelogo:newImage];
returntargetImage;
}
- (NSString*)imagePath {
NSString*documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)firstObject];
NSString*filePath = [documentsPathstringByAppendingPathComponent:@"imageFile"];
returnfilePath;
}
- (void)saveLocalPhoto {
UIImage*image = [selfimageAddImage];
NSData*data;
if(UIImagePNGRepresentation(image) ==nil) {
data =UIImageJPEGRepresentation(image,1);
}else{
data =UIImagePNGRepresentation(image);
}
NSFileManager*fileManager = [NSFileManagerdefaultManager];
NSString*filePath = [selfimagePath];
NSDate*date = [NSDatedate];
NSDateFormatter*dateFormatter = [[NSDateFormatteralloc]init];
dateFormatter.dateFormat=@"yyyyMMddhhmmss";
NSString*str = [dateFormatterstringFromDate:date];
if([fileManagercreateFileAtPath:[filePathstringByAppendingString:[NSStringstringWithFormat:@"/%@.png",str]]contents:dataattributes:nil]) {
[JGManagerToolsetSVProgressType:SVProgressHUDSuccessSVProgressText:@"保存成功"SVProgressProgress:0SVProgressImage:nil];
[JGManagerTooldissSVProgress:2.0];
[selfdismissViewControllerAnimated:YEScompletion:nil];
}else{
[JGManagerToolsetSVProgressType:SVProgressHUDErrorSVProgressText:@"保存失败"SVProgressProgress:0SVProgressImage:nil];
[JGManagerTooldissSVProgress:1.0];
}
}
2、取出图片显示
只要取出图片路劲就行
NSString*imagePath = 图片路径;
NSData*data = [NSDatadataWithContentsOfFile:imagePath];
[UIImageimageWithData:data]
