问题1：loadNibNamed
static NSString *cellId = @"AboutTableViewCell";
AboutTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
if(!cell)
{
cell = [[[NSBundle mainBundle]loadNibNamed:@"AboutTableViewCell" owner:self options:nil] lastObject];
}
原因：I suspect that your leak may be coming from the outlets in the nib. Note this phrase in the docs on loadNibNamed::
To establish outlet connections, this method uses the setValue:forKey: method, which may cause the object in the outlet to be retained automatically.
In other words, loadNibNamed sometimes imposes an extra retain because of the odd way key-value-coding works.
However, that is speculation, and there's no need for it, because there's no need for you to call loadNibNamed: in the first place!
You're using a custom UITableViewCell subclass, designed in a nib? Then why not do this the normal way? Make a nib containing one top-level object: the cell. Design the cell in the nib, set its class, hook up its outlets etc. In your code, call registerNib:forCellReuseIdentifier: on the table view, to tell the table view about your nib. When you later call dequeueReusableCellWithIdentifier:, if there are no free cells in the reuse pile, the table view will load your nib and hand you cell. No muss, no fuss.
问题2：imageWithRenderingMode
tabBarItem1.selectedImage = [[UIImage imageNamed:@"img_wifi_hl"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
暂时未找到解决办法
问题3：id bridge
- (id)fetchSSIDInfo
{
NSArray *ifs = CFBridgingRelease(CNCopySupportedInterfaces());
id info = nil;
for (NSString *ifnam in ifs) {
info = CFBridgingRelease(CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam));
if (info && [info count]) {
break;
}
}
return info;
}
CFBridgingRelease 替换掉原来的（id bridge）
