drawInRect：withFont：lineBreakMode：alignment：'不推荐使用：警告 [英] drawInRect:withFont:lineBreakMode:alignment:' is deprecated: warning

问题描述

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

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

在此代码中，我在iOS 7中收到以下警告：

In this code I am getting the below warning in iOS 7:

/wm/Traffic_Department/PMCalendar/src/PMCalendarView.m:150:56：'drawInRect：withFont：lineBreakMode：alignment：'不推荐使用：首先在iOS 7.0中弃用 - 使用-drawInRect：withAttributes：

/wm/Traffic_Department/PMCalendar/src/PMCalendarView.m:150:56: 'drawInRect:withFont:lineBreakMode:alignment:' is deprecated: first deprecated in iOS 7.0 - Use -drawInRect:withAttributes:

如何删除此警告？

谢谢

推荐答案

请尝试以下操作。

 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是您想要绘制的字符串。
我希望它有所帮助。

While textToDraw is string that you want to draw. I hope it helps.
