A method for forwarding traffic in an application on a mobile intelligent terminal, configured to be compatible with iOS operating system, comprising: 1)when an application in the iOS operating system is starting, determining whether a proxy service is required based on a configuration of the application, and when the proxy service is required, the application executing a network proxy managing operation by: replacing a native HTTP proxy function in a dynamic library of the iOS operating system with an updated HTTP proxy function, the updated HTTP function including information of a proxy server; and replacing a native Socket connect-create function in the dynamic library of the iOS operating system with an updated Socket connect-create function, a connection target of the updated Socket connect-create function being the proxy server; 2)when the application sends a HTTP request or a HTTPs request, utilizing the updated HTTP proxy function to point to the proxy server, and when the application sends a TCP/IP request, utilizing the updated Socket connect-create function to point to the proxy server, wherein in 1), a process of replacing the native HTTP proxy function in the dynamic library of the iOS operating system with the updated HTTP proxy function comprises: creating the updated HTTP proxy function, the updated HTTP proxy function including a first pointer address; calculating an offset value of the native HTTP proxy function in the dynamic library to obtain a second pointer address of the native HTTP proxy function in the dynamic library; and pointing the second pointer address to the updated HTTP proxy function and pointing the first pointer address to the native HTTP proxy function. 1)when an application in the iOS operating system is starting, determining whether a proxy service is required based on a configuration of the application, and when the proxy service is required, the application executing a network proxy managing operation by: replacing a native HTTP proxy function in a dynamic library of the iOS operating system with an updated HTTP proxy function, the updated HTTP function including information of a proxy server; and replacing a native Socket connect-create function in the dynamic library of the iOS operating system with an updated Socket connect-create function, a connection target of the updated Socket connect-create function being the proxy server; replacing a native HTTP proxy function in a dynamic library of the iOS operating system with an updated HTTP proxy function, the updated HTTP function including information of a proxy server; and replacing a native Socket connect-create function in the dynamic library of the iOS operating system with an updated Socket connect-create function, a connection target of the updated Socket connect-create function being the proxy server; 2)when the application sends a HTTP request or a HTTPs request, utilizing the updated HTTP proxy function to point to the proxy server, and when the application sends a TCP/IP request, utilizing the updated Socket connect-create function to point to the proxy server, wherein in 1), a process of replacing the native HTTP proxy function in the dynamic library of the iOS operating system with the updated HTTP proxy function comprises: creating the updated HTTP proxy function, the updated HTTP proxy function including a first pointer address; calculating an offset value of the native HTTP proxy function in the dynamic library to obtain a second pointer address of the native HTTP proxy function in the dynamic library; and pointing the second pointer address to the updated HTTP proxy function and pointing the first pointer address to the native HTTP proxy function. creating the updated HTTP proxy function, the updated HTTP proxy function including a first pointer address; calculating an offset value of the native HTTP proxy function in the dynamic library to obtain a second pointer address of the native HTTP proxy function in the dynamic library; and pointing the second pointer address to the updated HTTP proxy function and pointing the first pointer address to the native HTTP proxy function.
