Take the 2-minute tour ×  I see some UIStringDrawing methods
have been updated to use NSLineBreakMode instead of
UILineBreakMode in iOS 6.0:   - (CGSize)sizeWithFont:(UIFont
*)font constrainedToSize:(CGSize)size
lineBreakMode:(NSLineBreakMode)lineBreakMode  How can I check
for this to ensure my iOS 5 users and below continue to use
UILineBreakMode?  share|improve this question See this same
question, NSLineBreakMode enum and backwards compatibility. –

down vote accepted  No checking is necessary. These are just
enums and they map to the same values  You can see there is no
real difference here:  UILineBreakMode vs NSLineBreakMode
enum {    NSLineBreakByWordWrapping = 0, typedef NSUInteger
NSLineBreakMode  typedef enum {    UILineBreakModeWordWrap = 0,
} UILineBreakMode; share|improve this answer they are equal but
this offers no solution to the prob here –  Daij-Djan Sep 3 '13
