How to rotate UIImage

Question

I\'m developing an iOS app for iPad. Is there any way to rotate a UIImage 90º and then add it to a UIImageView? I\'ve tried a lot of different codes but none worked...

Answer 1

There is also imageWithCIImage:scale:orientation if you wanted to rotate the UIImage not the UIImageView

with one of these orientations:

typedef enum {
   UIImageOrientationUp,
   UIImageOrientationDown,   // 180 deg rotation
   UIImageOrientationLeft,   // 90 deg CW
   UIImageOrientationRight,   // 90 deg CCW
   UIImageOrientationUpMirrored,    // vertical flip
   UIImageOrientationDownMirrored,  // horizontal flip
   UIImageOrientationLeftMirrored,  // 90 deg CW then perform horizontal flip
   UIImageOrientationRightMirrored, // 90 deg CCW then perform vertical flip
} UIImageOrientation;
