下面是如何在iPhone非官方SDK程序中调用外部命令的方法。

- (NSString *)executeCommand: (NSString *)cmd

{

NSString *output = [NSString string];

FILE *pipe = popen([cmd cStringUsingEncoding: NSASCIIStringEncoding], "r");

if (!pipe) return;

char buf[1024];

while(fgets(buf, 1024, pipe)) {

output = [output stringByAppendingFormat: @"%s", buf];

}

pclose(pipe);

return output;

}

NSString *yourcmd = [NSString stringWithFormat: @"your command"];

[self executeCommand: yourcmd];
