我也試過這個

UIGraphicsBeginImageContext(CGSizeMake(width,height)); 
CGContextRef context = UIGraphicsGetCurrentContext();

UIImage *screenShot = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext();

你可以像這樣

CGRect rect = [captureView bounds]; 
UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f); 
CGContextRef context = UIGraphicsGetCurrentContext(); 
[captureView.layer renderInContext:context]; 
UIImage *capturedImage = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext()
