感谢您的帮助。执行此命令的结果显示在我的Xcode控制台中。在NSTextView中显示命令结果的最佳方法是什么?
NSString *commandToRun = @"~/Library/webREF/ffmpeg -nostats -i ~/Desktop/input.wav - filter_complex ebur128 -f null -";
NSTask *task;
task = [[NSTask alloc] init];
[task setLaunchPath: @"/bin/sh"];
NSArray *arguments = [NSArray arrayWithObjects:
@"-c" ,
[NSString stringWithFormat:@"%@", commandToRun],
nil];
NSLog(@"run command: %@",commandToRun);
[task setArguments: arguments];
NSPipe *pipe;
pipe = [NSPipe pipe];
[task setStandardOutput: pipe];
NSFileHandle *file;
file = [pipe fileHandleForReading];
[task launch];
答案 0 :(得分:0)
添加如下内容:
…
NSFileHandle *file;
file = [pipe fileHandleForReading];
NSMutableData *data = [[NSMutableData alloc] init];
NSData *inData = nil;
[task setStandardOutput:pipe];
[task launch];
[task waitUntilExit];
while ((inData = [file availableData]) && [inData length]) {
[data appendData:inData];
}
[file closeFile];
[task release];
[pipe release];
NSString *result = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
[data release];
// somewhere we have an NSTextView textView
[textView setString: result];
