Getting crash while adding attributes to NSMutableAttributedString for a particular range in iOS

Question

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]
                                                initWithString:@"I have read, understand and agree to the following terms and conditions and web usage policy." attributes:nil];
NSRange conditionlinkRange = NSMakeRange(50,70);
// for the word "terms and conditions" in the string above
NSRange policylinkRange = NSMakeRange(75,92);
NSDictionary *linkAttributes = @{ NSForegroundColorAttributeName : [UIColor colorWithRed:0.05 green:0.4 blue:0.65 alpha:1.0],
                                  NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle) };
[attributedString addAttributes:linkAttributes range:policylinkRange];
[attributedString addAttributes:linkAttributes range:conditionlinkRange];

Application gets crashed at this line [attributedString addAttributes:linkAttributes range:policylinkRange];

Please add some more elements to your question, just pasting here your code won't help users identify your problem. — Luca De Nardi, Nov 03 '17 at 10:11
My guess? `NSMakeRange(50,70)` should be `NSMakeRange(50,20)`. It's `(location, length)` not `(location, end)`. Same issue for the other range — Larme, Nov 03 '17 at 10:13

Try This

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"I have read, understand and agree to the following terms and conditions and web usage policy." attributes:nil];

NSRange conditionlinkRange = NSMakeRange(51,20);
NSRange policylinkRange = NSMakeRange(86,6);
NSDictionary *linkAttributes = @{ NSForegroundColorAttributeName : [UIColor colorWithRed:0.05 green:0.4 blue:0.65 alpha:1.0], NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle) };

[attributedString addAttributes:linkAttributes range:policylinkRange];
[attributedString addAttributes:linkAttributes range:conditionlinkRange];

Use this:

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"I have read, understand and agree to the following terms and conditions and web usage policy." attributes:nil];
    NSRange conditionlinkRange = [attributedString.string rangeOfString:@"terms and conditions"];

    // for the word "terms and conditions" in the string above
    NSRange policylinkRange = [attributedString.string rangeOfString:@"policy"];
    NSDictionary *linkAttributes = @{ NSForegroundColorAttributeName : [UIColor colorWithRed:0.05 green:0.4 blue:0.65 alpha:1.0],  NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle) };

    [attributedString addAttributes:linkAttributes range:policylinkRange];
    [attributedString addAttributes:linkAttributes range:conditionlinkRange];
