iOS 4.0之后NSDate的addTimeInterval方法被deprecated了

- (id)addTimeInterval:(NSTimeInterval)seconds

可以用dateByAddingTimeInterval来代替

- (id)dateByAddingTimeInterval:(NSTimeInterval)seconds;

iOS6.0中presentModalViewController过时了

self presentModalViewController:pNewController animated:YES];

替换为

[self presentViewController:pNewController animated:YES completion:nil];

iOS7.0中sizeWithFont过时了

CGFloat textSizeWidth = (self.textLabel != nil) ? [self.textLabel sizeWithFont:self.label.font constrainedToSize:maxLabelSize lineBreakMode:NSLineBreakByTruncatingTail].width : 0;

替换为

NSDictionary * tdic = [NSDictionary dictionaryWithObjectsAndKeys:self.label.font, NSFontAttributeName,nil];

CGFloat textSizeWidth =[self.textLabel boundingRectWithSize:maxLabelSize options:NSStringDrawingUsesLineFragmentOrigin |NSStringDrawingUsesFontLeading attributes:tdic context:nil].size.width;
