在iOS 7中，方法：- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(NSLineBreakMode)lineBreakMode 和方法：- (CGSize)sizeWithFont:(UIFont *)font不推薦使用。我該如何更換CGSize size = [string sizeWithFont:font constrainedToSize:constrainSize lineBreakMode:NSLineBreakByWordWrapping];和：CGSize size = [string sizeWithFont:font];

您可以嘗試以下方法：
CGRect textRect = [text boundingRectWithSize:size
options:NSStringDrawingUsesLineFragmentOrigin
attributes:@{NSFontAttributeName:FONT}
context:nil];
CGSize size = textRect.size;
只需將“ FONT”更改為“ [UIFont字體。...]”

這是簡(jiǎn)單的解決方案：
要求 ：
CGSize maximumSize = CGSizeMake(widthHere, MAXFLOAT);
UIFont *font = [UIFont systemFontOfSize:sizeHere];
現(xiàn)在constrainedToSizeusage:lineBreakMode:在iOS 7.0中已棄用用法：
CGSize expectedSize = [stringHere sizeWithFont:font constrainedToSize:maximumSize lineBreakMode:NSLineBreakByWordWrapping];
現(xiàn)在，在更高版本的iOS 7.0中的用法將是：
// Let's make an NSAttributedString first
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:stringHere];
//Add LineBreakMode
NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
[paragraphStyle setLineBreakMode:NSLineBreakByWordWrapping];
[attributedString setAttributes:@{NSParagraphStyleAttributeName:paragraphStyle} range:NSMakeRange(0, attributedString.length)];
// Add Font
[attributedString setAttributes:@{NSFontAttributeName:font} range:NSMakeRange(0, attributedString.length)];
//Now let's make the Bounding Rect
CGSize expectedSize = [attributedString boundingRectWithSize:maximumSize options:NSStringDrawingUsesLineFragmentOrigin context:nil].size;
