[Str boundingRectWithSize:CGSizeMake(MAXFLOAT,MAXFLOAT) options:options attributes:attributes context:context]
归来3个x,y=0的CGRect

Size

CGSizeMake(MAXFLOAT,MAXFLOAT)
会付给一个最合适的单行的尺码
CGSizeMake(300,MAXFLOAT)
范围文本宽度是300

options

NSStringDrawingUsesLineFragmentOrigin
唯有那一个能力测度出换行的Frame,即只要要总计多行的纯粹中度。

attributes

讲述字体的连带属性的字典,属性在UIKit的率先身长文件中
NSDictionary *textDict = @{NSFontAttributeName: textFont}

context

用得较少

写成NSString的项目方法
- (CGRect)textRectWithSize:(CGSize)size attributes:(NSDictionary *)attributes{ return [self boundingRectWithSize:size options:NSStringDrawingUsesLineFragmentOrigin attributes:attributes context:nil] }
