Iphone 如何设置UIButton上的标题

如何在

ui按钮上设置文本

topYellowButton2 = [UIButton buttonWithType:UIButtonTypeCustom];
topYellowButton2.frame = CGRectMake(80, 0, 90, 20);

[topYellowButton2 setTitleColor:[UIColor colorWithRed:0.0 green:0.6 blue:1.0 alpha:1.0] forState:UIControlStateNormal];

只需添加以下行：

[topYellowButton2 setTitle:@"my button" forState:UIControlStateNormal];

试试这个

topYellowButton2=[UIButton buttonWithType:UIButtonTypeCustom]; 
topYellowButton2.frame=CGRectMake(80, 0, 90, 20);
[topYellowButton2 setTitle:@"Your Title" forState:UIControlStateNormal];

设置普通和高亮显示的标题

[topYellowButton2 setTitle:@"Button Title" forControlState:UIControlStateNormal];
[topYellowButton2 setTitle:@"Button Title" forControlState:UIControlStateHighlighted];

[topYellowButton2 setTitle:@"Button Title" forControlState:UIControlStateNormal];
[topYellowButton2 setTitle:@"Button Title" forControlState:UIControlStateHighlighted];
