   #pragma mark -TextField Delegate Method

   -(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
       [self showKeyboard];
       return NO;  // Hide both keyboard and blinking cursor.

推荐答案

您可以尝试以下方法:

self.txtPrice.font = [UIFont systemFontOfSize: 14.0];
self.txtPrice.adjustsFontSizeToFitWidth = YES;
self.txtPrice.minimumFontSize = 7.0;

"adjustsFontSizeToFitWidth"是一个布尔值，指示是否应减小字体大小以使文本字符串适合文本字段的边界矩形.

"adjustsFontSizeToFitWidth" is a Boolean value indicating whether the font size should be reduced in order to fit the text string into the text field’s bounding rectangle.

"minimumFontSize"是用于绘制文本字段文本的最小允许字体的大小.

"minimumFontSize" is the size of the smallest permissible font with which to draw the text field’s text.
