NSImage *myNewIconImage=[[NSImage imageNamed:@"FanImage"] copy];
[myNewIconImage lockFocus];
[@"15" drawAtPoint:NSZeroPoint withAttributes:nil];
[myNewIconImage unlockFocus];
[myNewIconImage setTemplate:YES];
[[NSApplication sharedApplication]] setApplicationIconImage:myNewIconImage];
我正在尋找一種方法來簡單地在這個影像上寫入一個字串......并且非常短。這對我不起作用。
uj5u.com熱心網友回復：
以下代碼將在 NSImage 上放置一個可變屬性字串：
NSImageView *imageView = [[NSImageView alloc] initWithFrame:NSMakeRect( 0, 0, _wndW, _wndH )];
[[window contentView] addSubview:imageView];
NSImage *image = [NSImage imageNamed:@"myImage.jpg"];
[image lockFocus];
NSMutableDictionary *attr = [NSMutableDictionary dictionary];
[attr setObject:[NSFont fontWithName:@"Lucida Grande" size:36] forKey:NSFontAttributeName];
[attr setObject: [NSNumber numberWithFloat: 10.0] forKey: NSStrokeWidthAttributeName];
[attr setObject:[NSColor whiteColor] forKey:NSForegroundColorAttributeName];
NSString *myStr = @"Welcome to Cocoa";
NSMutableAttributedString *s = [[NSMutableAttributedString alloc] initWithString: myStr attributes:attr];
[s drawAtPoint:NSMakePoint(130,130)];
[image unlockFocus];
[imageView setImage:image];
