修改老项目时 遇到的一些警告～

copy警告：'sizeWithFont:' is deprecated: first deprecated in iOS 7.0 - Use -sizeWithAttributes:

修改前：CGSize xxxxSize =[xxxxString sizeWithFont:xxxxFont];

修改后：CGSize xxxxSize =[xxxxString sizeWithAttributes:@{NSFontAttributeName:xxxxFont}];

copy警告： 'sizeWithFont:constrainedToSize:lineBreakMode:' is deprecated: first deprecated in iOS 7.0 - Use -boundingRectWithSize:options:attributes:context:

修改前：CGSize xxxxSize =[xxxxString sizeWithFont:XXXXFont constrainedToSize:CGSizeMake(xxxxWidth, xxxxMAXFLOAT) lineBreakMode:xxxxNSLineBreakMode];

修改后：NSMutableParagraphStyle *paragraphStyle =[[NSParagraphStyle defaultParagraphStyle] mutableCopy];

paragraphStyle.lineBreakMode = xxxxNSLineBreakMode;//无NSMutableParagraphStyle时，忽略

CGSize xxxxSize = [xxxxString boundingRectWithSize:CGSizeMake(<#CGFloat width#>, <#CGFloat height#>)

                                                       options:<#(NSStringDrawingOptions)#>

                                                    attributes:<#(nullable NSDictionary<NSString *,id> *)#>

                                                       context:<#(nullable NSStringDrawingContext *)#>].size;

CGSize xxxxSize = [xxxxString boundingRectWithSize:CGSizeMake(xxxxWidth, xxxxMAXFLOAT) 

                                                       options:xxxxNSStringDrawingOptions

                                                    attributes:@{NSFontAttributeName:xxxxFont,NSParagraphStyleAttributeName:paragraphStyle}
