Here i got error like dictionary length ? 在这里我得到像字典长度的错误? Please help me how can i pass the array of image url to nsdata ?
请帮助我如何将图像URL数组传递给nsdata?
Thank you in-advance. 先感谢您。
In the code you have posted you are creating an NSData object and then calling objectForKey:
on it. 在发布的代码中,您将创建一个NSData对象,然后在其上调用
objectForKey:
This is not a method of NSData. 这不是NSData的方法。
Just assign the NSData you created to your imageData variable. 只需将创建的NSData分配给imageData变量即可。
