enum Values to NSString (iOS)

Question

I have an enum holding several values:

enum {value1, value2, value3} myValue;

In a certain point in my app, I wish to check which value of

Answer 1

I will introduce is the way I use, and it looks better than previous answer.(I thinks)

I would like to illustrate with UIImageOrientation for easy understanding.

typedef enum {
    UIImageOrientationUp = 0,            // default orientation, set to 0 so that it always starts from 0
    UIImageOrientationDown,          // 180 deg rotation
    UIImageOrientationLeft,          // 90 deg CCW
    UIImageOrientationRight,         // 90 deg CW
    UIImageOrientationUpMirrored,    // as above but image mirrored along other axis. horizontal flip
    UIImageOrientationDownMirrored,  // horizontal flip
    UIImageOrientationLeftMirrored,  // vertical flip
    UIImageOrientationRightMirrored, // vertical flip
} UIImageOrientation;

create a method like:

NSString *stringWithUIImageOrientation(UIImageOrientation input) {
    NSArray *arr = @[
    @"UIImageOrientationUp",            // default orientation
    @"UIImageOrientationDown",          // 180 deg rotation
    @"UIImageOrientationLeft",          // 90 deg CCW
    @"UIImageOrientationRight",         // 90 deg CW
    @"UIImageOrientationUpMirrored",    // as above but image mirrored along other axis. horizontal flip
    @"UIImageOrientationDownMirrored",  // horizontal flip
    @"UIImageOrientationLeftMirrored",  // vertical flip
    @"UIImageOrientationRightMirrored", // vertical flip
    ];
    return (NSString *)[arr objectAtIndex:input];
}

All you have to do is :

1. name your function.

2. copy contents of enum and paste that between NSArray *arr = @[ and ]; return (NSString *)[arr objectAtIndex:input];

3. put some @ , " , and comma

4. PROFIT!!!!
