iphone - NSURL URLWithString : giving nil

Question

请参阅以下代码:

UIImage *image;
NSString *str = [[[Data getInstance]arrPic]objectAtIndex:rowIndex];
NSLog(str);
NSURL *url = [NSURL URLWithString:str];
NSData *data = [NSData dataWithContentsOfURL:url];
image = [UIImage imageWithData:data];  

str 给了我 http://MyDomain/Pics\\1.png但 url 给了我nil。

Answer 1

尝试使用这个，

[NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
