“drawInRect:withFont:lineBreakMode:alignment:”已被弃用：警告

Question

[string drawInRect: rect
              withFont: self.font
         lineBreakMode: NSLineBreakByWordWrapping
             alignment: NSTextAlignmentCenter];

[((NSString *)[dayTitles objectAtIndex:index]) drawInRect: dayHeaderFrame 
                                                     withFont: calendarFont 
                                                lineBreakMode: NSLineBreakByWordWrapping
                                                    alignment: NSTextAlignmentCenter];

在这段代码中，我在iOS 7中收到以下警告:

/wm/Traffic_Department/PMCalendar/src/PMCalendarView.m:150:56: 'drawInRect:withFont:lineBreakMode:alignment:'已被弃用: 在iOS 7.0中首次被弃用 - 使用-drawInRect:withAttributes:

我该如何消除这个警告？

谢谢

尝试以下步骤。

 NSString *font = @"Courier-Bold";
    #ifdef __IPHONE_7_0
        NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
        paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
        paragraphStyle.alignment = NSTextAlignmentCenter;
        [textToDraw drawInRect:renderingRect withAttributes: @{NSFontAttributeName: font,
                                                                           NSParagraphStyleAttributeName: paragraphStyle }];
        #else
        [textToDraw drawInRect:renderingRect withFont:font lineBreakMode:NSLineBreakByWordWrapping alignment:NSTextAlignmentCenter];
        #endif

textToDraw是你想要绘制的字符串。

希望这可以帮到你。
