转换png ＋ 发现一个很好的做app icns的工具

icns tool

用了下，蛮好用，导入png，转成icns

转换成png的方法

- (void)saveImage:(NSImage *)image atPath:(NSString *)path {

    NSBitmapImageRep *newRep = [NSBitmapImageRep imageRepWithData:image.TIFFRepresentation];

    NSDictionary * properties = nil;

    

    NSBitmapImageFileType type = NSPNGFileType;

// 其他格式，改这个type

    NSData *pngData = [newRep representationUsingType:type properties:properties];

    [pngData writeToFile:path atomically:YES];

    

    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        if ([[NSFileManager defaultManager] fileExistsAtPath:path]) {

            [[NSWorkspace sharedWorkspace] selectFile:path inFileViewerRootedAtPath:@""];

        }

    });

}

然后用工具转
