If you are dealing with financial computations, you really should use base-10 arithmetic to avoid the rounding errors that can occur with the standard base-2 floating point types. So it’s either NSDecimal or NSDecimalNumber. And since you’re writing object-oriented code, NSDecimalNumber is the right choice for you. To answer your questions: only testing of your … Read more
You can use stringWithFormat:, passing in a format of %c to represent a character, like this: char c=”a”; NSString *s = [NSString stringWithFormat:@”%c”, c];
I compared MFMailComposeResult documentation on both Xcode 5 and Xcode 6. In Swift, MFMailComposeResult is a struct struct MFMailComposeResult { init(_ value: CUnsignedInt) // available in iPhone 3.0 var value: CUnsignedInt } with MFMailComposeResultCancelled as a constant of type MFMailComposeResult: var MFMailComposeResultCancelled: MFMailComposeResult { get } while it’s an enum in Objective-C: enum MFMailComposeResult { … Read more
That’s because your CustomiPhoneLib.a is a fat library, i.e., a library that contains more than one target architecture, namely armv6 and armv7 on iOS. You can use lipo to extract a specific architecture into another .a file, use ar and ranlib to manipulate it at will, and then use lipo again to recombine the manipulated … Read more
Your UITableview contains UIView, so just use this below lines of code for making it rounded corners. Also write this below line of code inside your tableview methods //If iOS version < 10 For Objective-C: cell.contentView.layer.cornerRadius = 5; cell.contentView.layer.masksToBounds = YES; For Swift: cell.contentView.layer.cornerRadius = 5 cell.contentView.layer.masksToBounds = true //If iOS version >= 10 For … Read more
This falls under the easy, but not obvious class of iPhone programming problems. Worthy of a quick post: The headers for an HTTP connection are included in the NSHTTPURLResponse class. If you have an NSHTTPURLResponse variable you can easily get the headers out as a NSDictionary by sending the allHeaderFields message. For synchronous requests — … Read more
I was able to solve this using the solution provided in this Apple Support Communities thread: The real problem here is at Build Settings in the session: Apple LLVM 5.0 – Language – Modules, we should set Enable Modules (C and Objective C) to NO
