是否有可能调整UIButton的位置x，y titleLabel？ [英] is it possible to adjust position x,y titleLabel of UIButton?

问题描述

这是我的代码

UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

[btn setFrame:CGRectMake(0.0f, 0.0f, 100.0f, 100.0f)];
[btn setTitle:[NSString stringWithFormat:@"Button %d", i+1] forState:UIControlStateNormal];     
[btn addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
btn.titleLabel.frame = ???

推荐答案

//make the buttons content appear in the top-left
[button setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];
[button setContentVerticalAlignment:UIControlContentVerticalAlignmentTop];

//move text 10 pixels down and right
[button setTitleEdgeInsets:UIEdgeInsetsMake(10.0f, 10.0f, 0.0f, 0.0f)];

在Swift中

//make the buttons content appear in the top-left
button.contentHorizontalAlignment = .Left
button.contentVerticalAlignment = .Top

//move text 10 pixels down and right
button.titleEdgeInsets = UIEdgeInsetsMake(10.0, 10.0, 0.0, 0.0)
