iOS 7 sizeWithAttributes:替换字体大小:constrainedToSize
iOS 7 sizeWithAttributes:替换字体大小:constrainedToSize
提问于 2013-10-03 03:18:49
如何从新的iOS 7方法CGSize返回多行文本sizeWithAttributes？
我希望这会产生与sizeWithFont:constrainedToSize相同的结果。
NSString *text = @"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus eu urna quis lacus imperdiet scelerisque a nec neque. Mauris eget feugiat augue, vitae porttitor mi. Curabitur vitae sollicitudin augue. Donec id sapien eros. Proin consequat tellus in vehicula sagittis. Morbi sed felis a nibh hendrerit hendrerit. Lorem ipsum dolor sit."
CGSize textSize = [text sizeWithAttributes:@{ NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Light" size:16.0] }];此方法仅生成单行文本的高度。

你可以试试这个：
NSDictionary *attributes = @{NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue" size:14]};
// NSString class method: boundingRectWithSize:options:attributes:context is
// available only on ios7.0 sdk.
CGRect rect = [textToMeasure boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributes
context:nil];Stack Overflow用户

我是这样做的：
// Get a font to draw it in
UIFont *font = [UIFont boldSystemFontOfSize: 28];
CGRect textRect;
NSDictionary *attributes = @{NSFontAttributeName: font};
// How big is this string when drawn in this font?
textRect.size = [text sizeWithAttributes:attributes];
// Draw the string
[text drawInRect:textRect withAttributes:attributes];Stack Overflow用户

这是我处理这两种情况的方法，属于NSString类别。
- (CGSize) sizeWithFontOrAttributes:(UIFont *) font {
if (IS_IOS7) {
NSDictionary *fontWithAttributes = @{NSFontAttributeName:font};
return [self sizeWithAttributes:fontWithAttributes];
} else {
return [self sizeWithFont:font];
}
