I am using this code in my app which will help me to send a image.
However, I have an image view with an image. I have no file in appbundle but have the image in my side. How can I change the below code ? Can anyone tell me how can I convert
// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"jpg"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/jpeg" fileName:@"rainy"];
Try one of the following, depending on your image format:
Returns the data for the specified image in JPEG format.
NSData * UIImageJPEGRepresentation ( UIImage *image, CGFloat compressionQuality );
Returns the data for the specified image in PNG format
NSData * UIImagePNGRepresentation ( UIImage *image );
if you want to access the raw bytes that make up the UIImage, you could use this approach:
CGDataProviderRef provider = CGImageGetDataProvider(image.CGImage); NSData* data = (id)CFBridgingRelease(CGDataProviderCopyData(provider)); const uint8_t* bytes = [data bytes];
This will give you the low-level representation of the image RGB pixels.
CFBridgingRelease bit if you are not using ARC).
