1、照片选择完成
- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
[pickerdismissViewControllerAnimated:YEScompletion:nil];
photo= [infoobjectForKey:UIImagePickerControllerEditedImage];
CGSizeimagesize =photo.size;
imagesize.height=imagesize.height*1024/imagesize.width;
imagesize.width=1024;
//对图片大小进行压缩--
photo= [ImageUtilimageWithImage:photoscaledToSize:imagesize];
[self.tableViewreloadData];
[selfimageUpToWebAction:photo];
}
2、上传照片
#pragma mark ----上传图片
-(void)imageUpToWebAction:(UIImage*)image
{
[selfshowMessage:@"头像上传中..."];
NSString*urlString = [NSStringstringWithFormat:@"%@/photoupload",addressUrl];
[managerPOST:urlStringparameters:nilconstructingBodyWithBlock:^(id formData) {
NSData*imageData =UIImageJPEGRepresentation(image,0.00001);
NSDateFormatter*formatter = [[NSDateFormatteralloc]init];
formatter.dateFormat=@"yyyyMMddHHmmss";
NSString*str = [formatterstringFromDate:[NSDatedate]];
NSString*fileName = [NSStringstringWithFormat:@"%@.jpg", str];
//上传图片，以文件流的格式
[formDataappendPartWithFileData:imageDataname:@"importFile"fileName:fileNamemimeType:@"image/jpeg"];
}success:^(AFHTTPRequestOperation*operation,idresponseObject) {
[selfhideHUD];
NSString*status=[responseObjectobjectForKey:@"status"];
NSString*message=[responseObjectobjectForKey:@"message"];
if([statusboolValue]){
_urlString= [NSStringstringWithString:message];
[selfsaveUserImage:message];
}else{
[selfshowError:message];
}
}failure:^(AFHTTPRequestOperation*operation,NSError*error) {
[selfshowError:[error.userInfoobjectForKey:@"NSLocalizedDescription"]];
}];
}
3、压缩照片
//对图片尺寸进行压缩--
+(UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize
{
// Create a graphics image context
UIGraphicsBeginImageContext(newSize);
// Tell the old image to draw in this new
context, with the desired
// new size
[imagedrawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
// Get the new image from the context
UIImage* newImage =UIGraphicsGetImageFromCurrentImageContext();
// End the context
UIGraphicsEndImageContext();
// Return the new image.
returnnewImage;
}
4、
AFHTTPRequestOperationManager*manager;
manager= [AFHTTPRequestOperationManagermanager];
