[英]Getting crash while adding attributes to NSMutableAttributedString for a particular range in iOS
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];
应用程序在此行崩溃[attributedString addAttributes:linkAttributes range:policylinkRange];
尝试这个
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];
用这个:
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];
