NSURL
打印null
。什么原因?
NSString *webStr = [[NSString alloc] initWithFormat:@"%@",[webArray objectAtIndex:1]];
NSLog(@"urlString = %@",webStr); // its printing correct url string
NSURL *webURL = [[NSURL alloc] initWithString:webStr];
NSLog(@"url = %@",webURL); // its printing null
[webURL release];
[webStr release];
最佳答案
您应该执行以下操作。
NSString *webStr = [[NSString alloc] initWithFormat:@"%@",[webArray objectAtIndex:1]];
NSLog(@"urlString = %@",webStr); // its printing correct url string
NSURL *webURL = [[NSURL alloc] initWithString:[webStr stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]];
NSLog(@"url = %@",webURL); // it should print it
[webURL release];
[webStr release];
我使用了NSASCIIStringEncoding,但是您也可以使用UTF8或任何其他编码。
