I can´t solve this problem.....

NSString *im = [[NSString alloc] initWithString: [imagen valueForKey:@"return"]];
NSData * imagenDecode = [envio base64DataFromString:im];
[envio save:imagenDecode];

Answer 1

You've set your SDK to one of the Mac OS X SDKs, not an iPhone SDK. Mac OS X doesn't have the UIKit.

Answer 2

Seems like you messed something up with architectures. So compilers thinks it is compiling for Mac OS instead of iOS. Check your build settings and/or regenerate schemes(Product->Manage Schemes->Autogenerate).
